You should spend
about 20 minutes on Questions 28-40, which are
based on Reading Passage 3 on the
following pages.
Life beyond
Earth
A
We all have our suppositions, our
scenarios. The late astronomer Carl Sagan
estimated that there are a million
technological civilizations in our
galaxy alone. His more conservative callable Frank
Drake offers the number
10,
Oro,
a
pioneering
comet
researcher,
calculates
that
the
Milky
Way
is
sprinkled
with
a
hundred
civilizations. And finally there are
skeptics like Ben Zuckerman, an astronomer at
UCLA, who thinks we may
as well be
alone in this galaxy if not in the universe.
B
All the estimates are highly
speculative. The fact is that there is no
conclusive evidence of any life beyond Earth.
Absence of evidence is not evidence of
absence, as various pundits have wisely noted. But
still we don?t have
any solid knowledge
about a single alien microbe, a solitary spore,
much less the hubcap from a passing alien
starship.
C
Our ideas about
extraterrestrial life are what Sagan called
“plausibility arguments,” usually shot through
with
unknowns, hunches, ideologies, and
random ought-to-bes. Even if we convince ourselves
that there must be life
out
the
re, we confront a second problem,
which is that we don?t know anything about that
life. We don?t know
how truly alien it
is. We don?t know if it is built on a foundation
of carbon atoms. We don?t know if it requires a
liquid-water medium, if it swims or
flies or burrows.
D
Despite .the enveloping nebula of
uncertainties, extraterrestrial life has become an
increasingly exciting area of
scientific inquiry. The field is called
exobiology or astrobiology or bioastronomy---
every few years it seems as
though the
name has been changed to protect the ignorant.
E
Whatever it?s called, this is a science
infused with optimism. We now know that the
universe may be as warm
with planets.
Since 1995 astronomers have detected at least 22
planets orbiting other stars. NASA hopes to build
a
telescope
called
the
Terrestrial
Planet
Finder
to
search
for
Earth-like
planets,
examining
them
for
the
atmospheric signatures of a living
world. In the past decade organisms have been
found thriving on our own
planet in
bizarre, hostile environments. If microbes can
live in the pores of rock deep beneath the earth
or at the
rim of a scalding Yellowstone
spring, then they might find a place like Mars not
so shabby.
F
Mars is in the midst of a
full-scale invasion from Earth, from polar landers
to global stevedores to rovers looking
for fossils .A canister of Mars rocks
will be rocketed back to Earth in the year 2008,
parachuting into the Utah
desert for
scrutiny by scientists in a carefully sealed lab.
In the coming years probes will also go around
and, at
some
point,
into
Jupiter?s
moon
Europe.
That
icy
world
shows
numerous
signs
of
having
a
subsurface
ocean-and could
conceivably harbor a dark cold biosphere.
G
The
quest for an alien microbe is supplemented by a
continuing effort to find something large,
intelligent, and
communicative.
SETI-the
Search
for
Extraterrestrial
Intelligence-has
not
yielded
a
confirmed
signal
from
an
alien
civilization
in
40
years
of
experiments,
but
the
signal-processing
technology
grows
more
sophisticated
ea
ch year. The optimists
figure it?s only a matter of time before we tune
in the right channel.
H
No
one
knows
when---
or
if---
one
of
these
investigations
might
make
a
break
through.
There?s
a
fair
bit
of
boosterism
surrounding the entire field, but I'd bet the
break through is many year, if not decades, away.
The
simple truth: extraterrestrial
life, by definition, is not conveniently located.
I
But there are other truths that sustain
the search for alien organisms. One is that,
roughly speaking, the universe
looks
habitable. Another is that life radiates
information about itself---
that, if nothing else, it usually
leaves a
residue or an imprint. If the
universe contains an abundance of life, that life
is not likely to remain forever in the
realm of the unknown.
J
Contact with an alien civilization
would be an epochal and culturally challenging
event, but exobiologist would
settle
gladly for the discovery of a tiny fossil, a mere
remnant of extraterrestrial biochemistry. One
example.
One data point to add to the
one we have---Earth life.
That?s what
we need to begin the long process of putting
human existence in its true cosmic
context.

1
The average air temperature
at the surface of the earth has risen this
century, as has the temperature of ocean
surface waters. Because water expands
as it heats, a warmer ocean means higher sea
levels. We cannot say definitely
that
the temperature rises are due to the greenhouse
effect; the heating may be part of a
long time-scale that we have not yet
recognized in our short 100 years of recording.
However, assuming the build up
of
greenhouse
gases
is
responsible,
and
that
the
warming
will
continue,
scientists--and
inhabitants
of
Iow-lying
coastal areas--
would like to know the extent of future sea level
rises.
2
Calculating
this
is
not
easy.
Models
used
for
the
purpose
have
treated
the
ocean
as
passive,
stationary
and
one-dimensional. Scientists have
assumed that heat simply diffused into the sea
from the atmosphere. Using basic
physical
laws,
they
then
predict
how
much
a
known
volume
of
water
would
expand
for
a
given
increase
in
temperature. But the oceans are not
one-dimensional, and recent work by
oceanographers, using a new model which
takes into account a number of subtle
facets of the sea--including vast and complex
ocean currents--suggests that the
rise
in sea level may be less than some earlier
estimates had predicted.

Day
after
day
we
hear
about
how
anthropogenic
development
is
causing
global
warming.
According
to
an
increasingly vocal minority, however,
we should be asking ourselves how much of this is
media hype and how much
is based on
real evidence. It seems, as so often is the case,
that it depends on which expert you listen to, or
which
statistics you study.
Yes, it is true that there is a mass of
evidence to indicate that the world is getting
warmer, with one of the world's
leading
weather predictors stating that air temperatures
have shown an increase of just under half a degree
Celsius
since the beginning of the
twentieth century. And while this may not sound
like anything worth losing sleep over, the
6
international press would have us
believe that the consequences could be
devastating. Other experts, however, are of
the opinion that what we are seeing is
just part of a natural upward and downward swing
that has always been part of
the cycle
of global weather. An analysis of the views of
major meteorologists in the United States showed
that less
than 20% of them believed
that any change in temperature over the last
hundred years was our own fault--the rest
attributed
it
to
natural
cyclical
changes.
There
is,
of
course,
no
denying
that
we
are
still
at
a
very
early
stage
in
understanding weather. The effects of
such variables as rainfall, cloud formation, the
seas and oceans, gases such as
methane
and ozone, or even solar energy are still not
really understood, and therefore the predictions
that we make
using them cannot always
be relied on. Dr. James Hansen, in 1988, was
predicting that the likely effects of global
warming would be a raising of world
temperature which would have disastrous
consequences for mankind:
cause and
effect relationship between the current climate
and human alteration of the
atmosphere
on record as stating that
using artificial models of climate as a way of
predicting change is all but impossible. In fact,
he now believes that, rather than
getting hotter, our planet is getting greener as a
result of the carbon dioxide increase,
with the prospect of increasing
vegetation in areas which in recent history have
been frozen wastelands.
In
fact,
there
is
some
evidence
to
suggest
that
as
our
computer-based
weather
models
have
become
more
sophisticated, the predicted rises in
temperature have been cut back. In addition, if we
look at the much reported rise
in
global temperature over the last century, a close
analysis reveals that the lion's share of that
increase, almost three
quarters in
total, occurred before man began to
greenhouse gas emissions in the second
half of the twentieth century.
So
should we pay any attention to those stories that
scream out at us from billboards and television
news headlines,
claiming that man, with
his inexhaustible dependence
on oil-based machinery and
ever more sophisticated forms
of
transport is creating a nightmare level of
greenhouse gas emissions, poisoning his
environment and ripping open
the ozone
layer? Doubters point to scientific evidence,
which can prove that, of all the greenhouse gases,
only two
percent come from man-made
sources, the rest resulting from natural
emissions.
Who,
then,
to
believe:
the
environmentalist
exhorting
us
to
leave
the
car
at
home,
to
buy
re-usable
products
packaged
in
recycled
paper
and
to plant
trees
in
our
backyard?
Or
the
sceptics,
including,
of
course, a
lot
of
big
businesses who have most to lose,
when they tell us that we are making a mountain
out of a molehill? And my own
opinion?
The jury's still out as far as I am concerned!

An international forum on climate
change, in 1986, produced figures for likely sea-
level rises of 20cm and 1.4m,
corresponding to atmospheric
temperature increases of 1.5 and 4.5 C
respectively. Some scientists estimate that the
ocean warming resulting from those
temperature increases by the year 2050 would raise
the sea level by between
10cm
and
40cm.
This
model
only
takes
into
account
the
temperature
effect
on
the
oceans;
it
does
not
consider
changes in sea
level brought about by the melting of ice sheets
and glaciers, and changes in ground water storage.
When we add on estimates of these, we
arrive at figures for total sea-level rises of
15cm and 70cm respectively.

Sydney 2000 olympics
1 The cost of staging the year 2000
Olympics in Sydney is estimated to be a stagger-
ing$$960 mi/lion, but the city is
preparing
t0
reap
the
financial
benefits
that
ensue
from
,holding
such
an
international
event
by
emulating
the
commercial success of Los Angeles, the
only city yet to have made a demonstrable profit
from the Games in 1984.
2 At precisely
4:20 am on Friday the 24th of September 1993, it
was announced that Sydney had beaten five other
competing cities around the world, and
Australians everywhere, not only Sydneysiders,
were justifiably proud of the
result.
But, if Sydney had lost the bid, would the
taxpayers of NSW and of Australia have approved of
governments
spending millions of
dollars in a failed and costly exercise?
3 There may have been some consolation
in the fact that the bid came in $$1 million below
the revised budget and $$5
million
below
the
original
budget
of
$$29
million
formulated
in
mid-1991.
However,
the
final
cost
was
the
considerable
sum
of
$$24
million,
the
bulk
of
which
was
paid
for
by
corporate
and
community
contributions,
merchandising,
licensing,
and
the
proceeds
of
lotteries,
with
the
NSW
Government,
which
had
originally
been
willing
to
spend
up
to
$$10
million,
contributing
some
$$2
million.
The
Federal
Governments
grant
of
$$5
million
meant, in effect,
that the Sydney bid was financed by every
Australian taxpayer.
4 Prior to the
announcement of the winning city, there was
considerable debate about the wisdom of taking
financial
risks of this kind at a time
of economic recession. Others argued that 70 per
cent of the facilities were already in
place, and all were on government-owned
land, removing some potential areas of conflict
which troubled previous
Olympic
bidders. The former NSW Premier, Mr. Nick Greiner,
went on record as saying that the advantage of
having
the Games
think the
real point of the Games is the psychological
change, the catalyst of confidence... apart from
the other more
obvious reasons, such as
the building of sporting facilities, tourism, and
things of that nature.
5 However, the
dubiousness of the benefits that Melbourne, an
unsuccessful bidder for the 1988 Olympic Games,
received
at
a
time
when
the
State
of
Victoria
was
still
in
economic
turmoil
meant
many
corporate
bodies
were
unenthusiastic.
6 There is no doubt that Sydney's
seductive physical charms caused the world's media
to compare the city favorably
to
its
rivals
Beijing,
Berlin,
Manchester,
and
Istanbul.
Mr.
Godfrey
Santer,
the
Australian
Tourist
Commission's
Manager of Corporate Planning Services,
stated that soon after the bid was made, intense
media focus was already
having a
beneficial effect on in-bound tourism.
7 Developers and those responsible for
community development projects eagerly pointed to
the improvements taking
place to the
existing infrastructure of the city, the creation
of employment, and especially the building of
sporting
facilities, all of which meet
the needs of the community and help to attract
more tourists. At Homebush Bay $$300
million was spent providing the twin
athletic arenas and the
impressive
legacy was the new attitude shown towards both
industrial relations and environmental problems.
The
high-profile
nature
of
the
bid;
and
the
perception
that
it
must
proceed
smoothly
created
a
unique
attitude
of
8
co-operation
between
the
workforce
and
employers
involved
in
the
construction
of
the
Olympic
Village
at
Homebush Bay. The improvements included
the lack of strikes, the breaking down of
demarkation barriers, and the
completion of projects within budget
and ahead of time.
8
The
Secretary
of
the
NSW
Labour
Council,
Mr.
Michael
Easson,
was
quoted
as
saying,
we've
achieved
should become the
model for the rest of the building industry ...
great co-operation, good management, improvement
in relations between employers and
employees, and a feeling of optimism
...
sporting facilities at Homebush Bay
and an industrial relations model which should
impact on the rest of the building
industry.
Improved
negotiations
and
co-operation
over
the
bid
between
the
Greenpeace
environmental
group
and
the
State
Government also saw a new respect
develop on both sides. Suddenly, environmentalists
were no longer regarded as
being
radically
opposed
to
all
development,
and
neither
was
the
State
Government
perceived
as
inconsiderate
towards
environmental concerns.
10
The
success
of
Sydney's
bid
laid
to
rest
much
of
the
opposition
to
the
gamble.
Nonetheless,
most
economists
agree that it
would be wise when considering future risks of
this kind to bear well in mind the financial
consequences
of failure.

Question22---26
Answer the
questions, below using NO MORE THAN THRESS WORDS
from the passage for each answer.
22.
Which of the senses is described here as being
involved in mating?
23. Which species
swim upside down while eating?
24. What
can bottlenose dolphins follow from under the
water?
25. Which type of habitat is
related to good visual ability?
26.
Which of the senses is best developed in
cetaceans?
What Do Whales
Feel?
A
Some
of
the
senses
that
we
and
other
terrestrial
mammals
take
for
granted
are
either
reduced
or
absent
in
cetaceans or fail to
function well in water. For example it appears
from their brain structure that toothed species
are unable to smell. Baleen species, on
the other hand, appear to have some related brain
structures but it is not
known whether
these are functional. It has been speculated that,
as the blowholes evolved and migrated to the top
of the head, the neural pathways
serving sense of smell may have been nearly all
sacrificed. Similarly, although at
least some cetaceans have taste buds,
the nerves serving these have degenerated or are
rudimentary.
B
The sense of touch has sometimes been
described as weak too, but this view is probably
mistaken. Trainers of
captive dolphins
and small whales often remark on their animals'
responsiveness to being touched or rubbed, and
both captive and free-ranging cetacean
individuals of all
species
(
particularly adults
and calves, or members of the
same
subgroup)appear
to
make
frequent
contact.
This
contact
may
help
to
maintain
order
within
a
group,
and
stroking
or
touching
are
part
of
the
courtship
ritual
in
most
species.
The
area
around
the
blowhole
is
also
9
particularly sensitive and captive
animals often object strangely to being touched
there.
C
The sense of vision is developed to
different degrees indifferent species. Baleen
species studied at close quarters
underwater---specifically a grey whale
calf in captivity for a year, and free-ranging
right whales and humpback
whales
studied and filmed off Argentina and Hawaii----
have obviously tracked objects with vision
underwater,
and
they
can
apparently
see
moderately
well
both
in
water
and
in
air.
However,
the
position
of
the
eyes
so
restricts
the field of vision in baleen whales that they
probably do not have stereoscopic vision.
D
On
the other hand, the position of the eyes in most
dolphin sand porpoises suggests that they have
stereoscopic
vision
forward
and
downward.
Eye
position
in
freshwater
dolphins,
which
often
swim
on
their
side
or
upside
down
while feeding, suggests that what vision they have
is stereoscopic forward and upward. By comparison,
the
bottlenose dolphin has extremely
keen vision in water. Judging from the way it
watches and tracks airborne flying
fish,
it
can
apparently
see
fairly
well
through
the
air-
water
interface
as
well.
And
although
preliminary
experimental evidence suggests that
their in air vision is poor, the accuracy with
which dolphins leap high to take
small
fish out of a trainer?s hand provides anecdotal
evidence to the contrary.
E
Such
variation
can
no
doubt
be
explained
with
reference
to
the
habitats
in
which
individual
species
have
developed
For
example,
vision
is
obviously
more
useful
to
species
inhabiting
clear
open
waters
than
to
those
living
in turbid rivers and flooded plains. The South
American bout and Chinese beige, for instance,
appear to
have very limited vision, and
the Indian souses are blind, their eyes reduced to
slits that probably allow them to
sense
only the direction and intensity of light.
F
Although the senses of taste and smell
appear to have deteriorated, and vision in water
appears to be uncertain,
such
weaknesses are more than compensated for by
cetaceans' well-developed acoustic sense. Most
species are
highly
vocal,
although
they
vary
in
the
range
of
sounds
they
produce,
and
many
forage
for
food
using
echolocation. Large baleen whales
primarily use the lower frequencies and are often
limited
in their repertoire.
Notable exceptions are the nearly song-
like choruses of bowhead whales in summer and the
complex, haunting
utterances
of
the
humpback
whales.
Toothed
species
in
general
employ
more
of
the
frequency
spectrum,
and
produce
a
wider
variety
of
sounds,
than
baleen
species
(though
the
sperm
whale
apparently
produces
a
monotonous
series
of
high-energy
clicks
and
little
else).
Some
of
the
more
complicated
sounds
are
clearly
communicative, although what role they
may play in the social life and 'culture' of
cetaceans has been more the
subject of
wild speculation than of solid science.

Paper Recycling
Paper
is
different
from
other
waste
produce
because
it
comes
from
a
sustainable
resource:
trees.
Unlike
the
minerals and oil used to make plastics
and metals, trees are replaceable. Paper is also
biodegradable, so it does not
pose as
much threat to the environment when it is
discarded. While 45 out of every 100 tonnes of
wood fibre used to
make
paper
in
Australia
comes
from
waste
paper,
the
rest
comes
directly
from
virgin
fibre
from
forests
and
plantations.
By
world
standards
this
is
a
good
performance
since
the
world-
wide
average
is
33
per
cent
of
waste
paper.
Governments
have
encouraged
waste
paper
collection
and
sorting
schemes
and
at
the
same
time,the
paper
industry
has
responded
by
developing
new
recycling
technologies
that
have
paved
the
way
for
even
greater
utilisation of used fibre. As a result,
industry's use of recycled fibres is expected to
increase at twice the rate of virgin
fibre over the
coming years.
Already waste paper constitutes 70% of
paper used for packaging and advances in
the technology required to
remove ink from the paper have allowed a higher
recycled
content in newsprint and
writing
paper.
To
achieve
the
benefits
of
recycling,
the
community
must
also
contribute.
We
need
to
accept
a
change
in
the
quality
of
paper
products:
for
example
stationery,
may
be
less
white
and
of
a
rougher
texture.
There also needs to be supported from
the community for waste paper collection programs.
Not only do we need to
make
the
paper
available
to
collectors
but
it
also
needs
to
be
separated
into
different
types
and
sorted
from
contaminants such as
staples paperclips, string
and other miscellaneous items.

People may think that
writing as a profession is glamorous; that it is
just about sitting down and churning out words
10
on a page, or more likely these days on
a computer screen. If only it were true! So what
exactly does writing a book
entail?
Being
a
writer
is
about
managing
a
galaxy
of
contradictory
feelings:
elation,
despair,
hope
frustration,
satisfaction and depression--and not
all Separately! Of course, it also involves
carrying out detailed research: first to
establish whether there is a market for
the planned publication, and second into the
content of the book. Sometimes
however,
instinct
takes
the
place
of
market
research
and
the
contents
are
dictatednot
by
plans
and
exhaustive
research, but
experience and knowledge.
Once the publication has been embarked
upon, there is a long period of turmoil as the
text takes shape. A first draft is
rarely the final text of the book.
Nearly all books are the result of countless hours
of altering and re-ordering chunks
of
text and deleting the embarrassing bits. While
some people may think that with new technology.
The checking and
editing process is
speeded up, the experienced writer would hardly
agree. Unfortunately, advanced technology now
allows the writer the luxury of
countless editings, a temptation many of us find
hard to resist. So a passage, endlessly
re-worked may end up nothing remotely
like the original, and completely out of place
when compared with the rest
of the
text.
After the trauma of
self-editing and looking for howlers, it is time
to show the text to other people--friends perhaps,
for appraisal. At this stage, it is not
wise to send it off to a literary agent or direct
to publishers, as it may need further
fine-tuning of which the author is
unaware. Once an agent has been approached and has
rejected a draft publication,
it
is
difficult
to
go
and
ask
for
the
re-vamped
text
to
be
considered
again.
It
also
helps,
at
this
stage,
to
offer
a
synopsis of the book, if it is a novel,
or an outline if it is a textbook. This acts as a
guide for the author, and a general
reference for friends and later for
agents.
Although it is
tempting to send the draft to every possible agent
at one time, it is probably unwise. Some agents
may
reject the publication out of hand,
but others may proffer some invaluable advice, for
example about content or the
direction
to be taken. Hints like this may be of use in
finally being given a contract by an agent or
publisher.
The few lucky
taken on by publishers or agents, then have their
books subjected to a number of readers, whose job
is
to vet a book: deciding whether it
is worth publishing and whether the text as it
stands is acceptable or not. After a
book
is
finally
accepted
by
a
publisher,
one
of
the
greatest
difficulties
for
the
writer
lies
in
taking
on
board
the
publisher's alterations to the text.
Whilst the overall story and thrust of the book
may be acceptable, it will probably
have to conform to an in-house style,
as regards language, spelling, or punctuation,
etc. More seriously, the integrity
of
the text may be challenged and this may require
radical re-drafting which is unpalatable to the
author. A book's
creation period is
complex and unnerving, but the publisher's
reworkings and text amputations can also be a
tortuous
many writers, the most
painful period comes when the text has been
accepted, and the writer is waiting
for
it to be put together for the printer. By this
stage, it is not uncommon for the writer to be
thoroughly sick of the
text.
Abandon writing? Nonsense.
Once smitten, it is not easy to escape the
compulsion to create and write, despite the
roller-coaster ride of contradictory
emotions.

SOME MISCONCEPTIONS ABOUT ABORIGINAL
AUSTRALIA
When
airline
pilot Percy
Trezise
began
to
explore
the
rock
art
galleries
of
Cape
York
peninsula
in
the
early
1960s -
a hobby that was to obsess him for the next 30
years-the consensus of academic opinion was that
Australia
had been peopled for less
than 10,000 years. Stone tools found in Kakadu
have now been dated to at least 50,000
years, and camp sites as diver as lake
Mungo in the Willandra lakes region of NSW and
W
A's upper Swan River
11
have yielded
tools charcoal radiocarbon- dated to between 38
000 and 45 000 years. More than a dozen other
sites
date to more than 30,000 years -
indisputable evidence, says archaeologist
Josephine Flood, of the great antiquity of
Aboriginal culture.
Thirty years ago, the first Australians
were still thought of as a backward race. Trezise
recalls in his book Dream
Road,
that
there
was
much
sage
discussion
on
whether
they
were
even
capable
of
abstract
thought.
Since
then,
reawakened
interest
in
and
growing
knowledge
of
Australia's
Aboriginal
heritage
has
demonstrated
that
this
is
a
complex, subtle and rich culture.
The closer we look at Australian
prehistory, the more it continues to confound our
assumptions. Until recently,
the
authoritative
view
was
that
the
population
of
Australia
at
the
time
of
the
arrival
of
Europeans
in
1788
was
probably somewhere
between 250 000 and 500 000. But the discovery,
beginning two years ago, of a vast Aboriginal
graveyard at Lake Victoria near the
confluence of the Murray and Darling rivers has
thrown even tail into doubt. At
least
10
000
skeletons
are
buried
in
the
sands
of
Lake
Victoria,
possible
as
many
as
40
000.
Researchers
are
wondering if they have stumbled on the
demographic hub of an infinitely more populous
prehistoric Australia than
was ever
previously supposed, at the crossroads of two of
its greatest river highways. Archaeologist Dr
Colin Pardoe
of
the
SA
museum
says
the
idea
of
300
000
or
so
people
in
Australia
before
white
settlement
must
be
radically
reevaluated.
we should be
thinking 10 times that,
Cribb noted,
this would be a greater population than pre- Roman
Britain's.
Thought
Aborigines might see themselves as indigenous (in
the sense, as Josephine Flood explains, that they
have
no
race
history
not
associated
with
this
continent)
there
is
no
doubt
that
they
were
in
fact
Australia's
first
migrants.
Their
springboard
was
provided
by
the
last
ice
age,
or
Pleistocene
period,
which
lasted
between
two
million and 10 000 years
ago. So much water was locked up on land that the
ocean level dropped perhaps 150 m.
There was never a complete land bridge
to south - east Asia, but Arnhem Land was linked
to Papua New Guinea for
most
of
the
past
100
000
years,
says
Flood,
and
this
would
have
been
one
of
the
easiest
routes
for
ice
-
age
immigrants
moving south. What is certain, says Flood in her
excellent book The Riches Of Ancient Australia, is
that
once here, the first Australians
spread rapidly. The inland would have been dry,
but considerably more hospitable
than
it
is
today.
The
inland
salt
pans
were
then
fresh-
water
lakes
teeming
with
fish,
and
the
country
was
much
greener.

For people
who like to keep poultry, ducks offer certain
advantages over hens. Ducks are immune to some
common
diseases found in hens and are
less vulnerable to others. Some breeds of duck
produce bigger eggs than hens. In
addition, ducks lay eggs over a longer
season than do hens.
Poultry keepers with gardens have less
to worry about if they keep ducks rather than hens
because the former are less
apt to dig
up plants and destroy roots. While both hens and
ducks benefit the garden by eating pests, hens are
known

Ducks, on the other hand, will search for insects
and snails more carefully. Only very
delicate plants are at risk from the
broad, webbed feet of ducks.
Like
all
water
birds,
ducks
need
access
to
water,
and
duck
keepers
typica!ly
provide
this
by
building
a
pond.
Something
this large is not absolutely necessary, however:
ducks need only to be able to dip their heads in
the water
to keep their nostrils clean.
If a pond is provided though it is important to
keep ducklings away from it until they are
12
old enough to withstand the cool
temperature of the water--about eight weeks.
When keeping ducks, one has
to consider just how many the land will support
generally the rule is 100 ducks per
half
hectare.
If
more
than
this
proportion
is
introduced,
there
is
a
risk
of
compacting
the
soil,
which
can
lead
to
muddy
conditions for long period as the rain is not
easily absorbed into the ground.
While ducks offer many advantages over
hens, they must be given greater quantity of food,
especially if regular eggs
are desired.
An adult duck will eat between 170 to 200 grams of
food a day. If the ducks have access to grass and
a
pond,
they
will
be
able
to
find
for
themselves
approximately
70%
of
their
daily
dietary,
requirements
in
warmer
months but less than
half that in colder times. Therefore. it is
important that they be fed enough food, such as
grain,
every day.

The effects of light on plant and
animal species
13
Light is important to
organisms for two different reasons. Firstly it is
used as a cue for the timing of daily and
seasonal rhythms in both plants and
animals, and it is used to assist growth in
plants.
Breeding
in
most
organisms
occurs
during
a
part
of
the
year
only,
and
so
a
reliable
cue
is
needed
to
trigger
breeding behavior.
Day length is an excellent cue, because it
provides a perfectly predictable pattern of change
within
the year. In the temperate zone
in spring, temperatures fluctuate greatly from day
to day, but day length increases
steadily
by
a
predictable
amount.
The
seasonal
impact
of
day
length
on
physiological
responses
is
called
photoperiodism, and the amount of
experimental evidence for this phenomenon is
considerable. For example, some
species
of birds? breeding can be induced even in
midwinter simply by increasing day length
artificially
(Wolfsan
1964).Other examples of photoperiodism
occur in plants. A short-day plant when the day is
less than a certain critical
length. A
long-day plant flowers after a certain critical
day length is exceeded. In both cases the critical
day length
differs from species to
species. Plants which flower after a period of
vegetative growth, regardless of photoperiod, are
known as day-neutral plants.
Breeding seasons in animals such as
birds have evolved to occupy the part of the year
in which offspring have
the greatest
chances of survival. Before the breeding season
begins, food reserves must be built up to support
the
energy cost of reproduction, and to
provide for young birds both when they are in the
nest and after fledging. Thus
many
temperate-zone birds use the increasing day
lengths in spring as a cue to begin the nesting
cycle, because this is
a point when
adequate food resources will be assured.
The adaptive significance of
photoperiodic in plants is also clear. Short-day
plants that flower in spring in the
temperate zone are adapted to
maximizing seedling growth during the growing
season. Long-day plants are adapted
for
situations that require fertilization by insects,
or a long period of seed ripening. Short-day
plants that flower in the
autumn in the
temperate zone are able to build up food reserves
over the growing season and over winter as seeds.
Day-neutral plants have an advantage
when the connection between the favorable period
for and day length is much
less
certain.
For
example,
desert
annuals,
flower
and
seed
whenever
suitable
rainfall
occurs,
regardless of
the
day
length.
The
breeding season of some plants can be delayed to
extraordinary lengths. Bamboos are perennial
grasses that
remain in a vegetative
state for many years and then suddenly flower,
fruit and die (Evans 1976). Every bamboo of
the species Chiquita abietifolia on the
island of Jamaica flowered, set seed and died
during 1884. The next generation
of
bamboo
flowered
and
died
between
1916
and
1918,
which
suggests
a
vegetative
cycle
of
about
31
years.
The
climatic trigger for this flowering
cycle is not
yet known, but the
adaptive significance is clear. The simultaneous
production of masses of bamboo seeds
(in some cases lying 12 to is centimeters deep on
the ground) is more than all
the seed-
eating animals can cope with at the time, so that
some seeds escape being eaten and grow up to form
the next
generation(Evans 1 976).
The
second reason light is important to organisms is
that it is essential for photosynthesis. This is
the process by
which plants use energy
from the sun to convert carbon from soil or water
into organic material for growth. The rate
of photosynthesis in a plant can be
measured by calculating the rate of its uptake of
carbon. There is a wide range of
photosynthetic
responses
of
plants
to
variations
in
light
intensity.
Some
plants
reach
maximal
photosynthesis
at
one-quarter full
sunlight, and others, like sugarcane, never reach
a maximum, but continue to increase photosynthesis
rate as light intensity rises.
Plants
in
general
can
be
divided
into
two
groups:
shade-tolerant
species
and
shade-intolerant
species.
This
classification is commonly
used in forestry and horticulture.
Shade-tolerant plants
have lower
photosynthetic
rates
and
hence have lower growth rates than those of shade-
intolerant species. Plant species become adapted
to living in a
certain kind of habitat,
and in the process evolve a series of
characteristics that prevent them from occupying
other
habitats.
Grime
(1966)
suggests
that
light
may
be
one
of
the
major
components
directing
these
adaptations.
For
example,
eastern
hemlock
seedlings
are
shade-tolerant.
They
can
survive
in
the
forest
understorey
under
very
lowlight levels because
they have a low photosynthetic rate.

Climate change is a legitimate worry.
Although still riddled with uncertainties, the
science of climate change is
becoming
firmer: put too much carbon in the atmosphere
and you might
end up cooking the earth, with possibly
catastrophic results. But here again,
switching immediately to nuclear power is not the
best response. Cutting the
hefty subsidies that go to the world's
coal producers would help tilt the world's
energy balance towards
natural gas,
which gives off
much less
carbon dioxide.
Developing countries
subsidise electricity prices
to the
tune of up to
$$120 billion a year,
according to World Bank estimates. If prices
reflected the true costs of generation,
electricity
demand would fall, thus
cutting greenhouse emissions.
2
Once the tough job of
cutting subsidies is over, governments might want
to reduce greenhouse gases further.
Again
there
are
carbon-free
energies
that
merit
more
subsidies
than
nuclear.
The
costs
of
many
renewable
technologies, such
as solar and wind power, have fallen dramatically
in recent decades.
3
Moreover,
supporting nuclear power to ward off climate
change means swapping one environmental risk for
another. V
oters in many
countries fear radiation like the plague. The
risks of nuclear accidents may be tiny, but when
14
they happen they can be catastrophic.
Renewables are not without their environmental
disadvantages (wind turbines,
for
example, can be unsightly on hilltops), but are
much cleaner than nuclear. The billions rich
countries each year
pump into nuclear
research would be better spent on renewables
instead.
4
Having been invented,
nuclear power will not disappear. The nuclear
industry still
has a job to
do, running
existing nuclear plants to
the end of their lives as cheaply
and safely as possible.
For
now, the case for nuclear
power is full
of holes. Asia should resist the temptation to
throw its money into them.

There are
technical limitations to the amount of paper which
can be recycled and some paper products cannot
be collected for re-use. These include
paper in the form of books and permanent records,
photographic paper and
paper which is
badly contaminated. The four most common sources
of paper for recycling are factories and retail
stores
which

goods

offices

paper
converters

printers
and
lastly
households
which
discard newspapers and
packaging material. The paper manufacturer pays a
price for the paper and may also incur
the collection cost.
Once
collected, the paper has to be sorted by hand by
people trained to recognize various types of
paper. This is
necessary because some
types of paper can only be made from particular
kinds of recycled fibre. The sorted paper
then has to be repulped or mixed with
water and broken down into its individual fibres.
This mixture is called stock
and may
contain a wide variety of contaminating materials
particularly if it is made from mixed waste paper
which
15
has had little sorting. Various
machinery is used to remove other materials from
the stock. After passing through the
repulsing process the fibres from
printed waste paper are grey in colour because the
printing ink has soaked into the
individual fibres. This recycled
material can only be used in products where the
grey colour does not matter such as
cardboard boxes but if the grey colour
is not acceptable, the fibres must be de-inked.
This involves adding chemicals
such as
caustic soda or other alkalis, soaps and
detergents, water hardening agents such as calcium
chloride, frothing
agents and bleaching
agents. Before the recycled fibres can be made
into paper they must be refined or treated in
such a way that they bond together.

An important part
of police strategy, rapid police response is seen
by police officers and the public alike as
offering
tremendous benefits. The more
obvious ones are the ability of police to apply
first-aid lifesaving techniques quickly
and the greater likelihood of arresting
people who may have participated in a crime. It
aids in identifying those who
witnessed
an emergency or crime, as well as in collecting
evidence. The overall reputation of a police
department,
too, is enhanced if rapid
response is consistent, and this in itself
promotes the prevention of crime. Needless to say,
rapid response offers the public some
degree of satisfaction in its police force.

(ix) Obstacles to quickly contacting

It becomes clear that the
importance of response time in collecting evidence
or catching criminals after a crime must
17
be weighed against a variety of
factors. Yet because police department officials
assume the public strongly demands
rapid response, they believe that every
call to the police should be met with it. Studies
have shown, however, that
while the
public wants quick response, more important is the
information given by the police to the
person asking
for help. If a
caller is told the police will arrive in five
minutes but in fact it takes ten minutes or more,
waiting the
extra time can be extremely
frustrating. But ifa caller is told he or she will
have to wait 10 minutes and the police
indeed
arrive
within
that
time,
the
caller
is
normally
satisfied.

Research at
the IRRI has indicated that intensive rice
production-growing two or three
crops a
year on the same land-is showing signs of yield
declines as great as 30 per cent.
Evidence for this comes from as far a
field as India, the Philippines and Indonesia. At
the
same time, agricultural research
worldwide has been contracting as governments,
non-government bodies and private
donors reduce funding because of domestic
economic pressures. This means, Lampe
says, that at risk is the capability to solve such
problems as rice yield decline and
research to breed the new generation of
super-~yielding
crops. Yet rice will be
needed to feed more than half the human
population.

Machete Integrated Rural Transport
Project
Section A
The disappointing results of many
conventional road transport in Africa led some
experts to rethink the strategy
by
which rural transport problems were to be tackled
at the beginning of the 1980s.A request for help
in improving
the availability of
transport within the remote Machete District of
south-western Tanzania presented the opportunity
to try a new approach.
The concept of
integrated rural transport was adopted in the task
of examining the transport needs of the rural
households in the district. The
objective was to reduce the time and effort needed
to obtain access to essential goods
and
services through an improved rural transport
system. The underlying assumption was that the
time saved would
be
used
instead
for
activities
that
would
improve
the
social
and
economic
development
of
the
communities.
The
Machete
Integrated
Rural
Transport
Project
(MIRTP)
started
in
1985
with
financial
support
from
the
Swiss
Development
Corporation and was co-ordinate with the help of
the Tanzanian government.
Section B
When
the
project
began,
Machete
District
was
virtually
totally
isolated
during
the
rainy
season.
The
regional
road
was in such bad shape that access to the main
towns was impossible for about three months of the
year. Road
traffic was extremely rare
within the district and alternative means of
transport were restricted to donkey in the north
of the district. People relied
primarily on the paths, which were slippery and
dangerous during the rains.
Before
solutions could be proposed, the problems had to
be understood. Little
was known about
the transport
demands so Phase I,
between December 1985 and December
1987
,
focused on research.
The socio-economic survey
of more than
400 households in the district indicated that a
household in Machete spent, on average, seven
hours a
day on transporting themselves
and their goods, a figure which seemed extreme but
which has also been obtained in
surveys
in other rural areas in Africa. Interesting facts
regarding transport were found: 95%was on foot;
80% was
within the locality; and 70%was
related to the collection of water and firewood
travelling to grinding mills.
Section C
Having determined the main transport
needs, possible solutions were identified which
might reduce the time and
burden.
During Phase II, from January to February 1991, a
number of approaches were implemented in an effort
to
improve mobility and access to
transport.
An improvement of the road network was
considered necessary to ensure the import and
export of goods to the
district. These
improvements were carried out using methods that
were heavily dependent on labor. In addition to
the
improvement of roads, these methods
provided training in the operation of a mechanic
workshop and bus and truck
services.
However,
the
difference
from
the
conventional
approach
was
that
this
consideration
was
given
to
local
transport needs
outside the road network.
Most goods
were transported along the paths that provided
short-cuts up and the hillsides, but the paths
were a
real safety risk and made the
journey on foot even more arduous. It made sense
to improve the paths by building
steps,
handrails and footbridges.
It
was
uncommon
to
find
means
of
transport
that
were
more
efficient
than
walking
but
less
technologically
advanced
than motor vehicles. The use of bicycles was
constrained by their high cost and the lack of
available spare
parts.
Oxen
were
not
used at
all
but
donkeys
were
used
by
a
few
households
in
the
northern
part
of
the
district.
MIRPT focused on
what would be most appropriate for the inhabitants
of Machete in terms of what was available,
how much they could afford and what
they were willing to accept.
After
careful consideration, the project chose the
promotion of donkeys
一
a
donkey costs less than a
bicycle
一
and the
introduction of locally manufacturability
wheelbarrow.
Section D
At
the
end
of
Phase
II,
it
was
clear
that
the
selected
approaches
to
Machete?s
transport
problems
had
had
different
degrees
of
success.
Phase
III,
from
March
1991to
March
1993,
focused
on
the
refinement
and
institutionalisation of
these activities.
The road improvements
and accompanying maintenance system had helped
make the district center accessible
throughout the year. Essential goods
from outside the district had become more readily
available at the market and
prices did
not fluctuate as much as they had done before.
Paths and secondary roads were improved
only at the request of communities who were
willing to participate in
