94. When 100 people who have not used cocaine are tested for cocaine use, on average only 5 will

test positive. By contrast, of every 100 people who have used cocaine 99 will test positive. Thus,

when a randomly chosen group of people is tested for cocaine use, the vast people is tested for

cocaine use, the vast majority of those who test positive will be people who have used cocaine.

A reasoning error in the argument is that the argument

(A) attempts to infer a value judgement from purely factual premises

(B)

attributes

to

every

member

of

the

population

the

properties

of

the

average

member

of

the

population

(C) fails to take into account what proportion of the population have used cocaine

(D) ignores the fact that some cocaine users do not test positive

(E) advocates testing people for cocaine use when there is no reason to suspect that they have used

99. Concetta: Franchot was a great writer because she was ahead of her time in understanding that

industrialization was taking an unconscionable toll on the family structure of the working class.

Alicia: Franchot was not a great writer. The mark of a great writer is the ability to move people

with the power of the written word, not the ability to be among the first to grasp a social issue.

Besides,

the social consequences of industrialization were widely understood in Franchot’s day.

100. Which one of the following can be properly inferred from Anson’s argument?

(A) Dr. Ladlow’s evidence that his theory generates consistently accurate predictions

about how

rats will perform in a maze is inaccurate.

(B) Psychologists who can derive consistently accurate predictions about how rats will perform in

a maze from their theories cannot responsibly conclude that those theories cannot be disproved.

(C)

No

matter

how

responsible

psychologists

are,

they

can

never

develop

correct

theoretical

explanations.

(D) Responsible psychologists do not make predictions about how rats will perform in a maze.

(E) Psychologists who accept the possibility that new evidence will show that their theories are

incorrect are responsible psychologists.

The brains of identical twins are genetically identical. When only one of a pair of identical twins is

a schizophrenic, certain areas of the affected twin’s brain are smaller than

corresponding areas in

the brain of the unaffected twin. No such differences are found when neither twin is schizophrenic.

Therefore, this discovery provides definitive evidence that schizophrenia is caused by damage to

the physical structure of the brain.

103. If the statements on which the conclusion above is based are all true, each of the following

could be true EXCEPT:

(A) People who lack a genetic susceptibility for the disease will not develop schizophrenia

people

without the disorder

(D) It will eventually be possible to determine whether or not someone will develop schizophrenia

on the basis of genetic information alone

(E) Brain abnormalities associated with schizophrenia are the result of childhood viral infections

that inhibit the development of brain cells

Because

of

the

recent

transformation

of

the

market,

Quore,

Inc.,

must

increase the next two years, or it will certainly go bankrupt. In fact, however, Quore’s production

structure is such that if a 10 percent productivity increase is possible, then a 20 percent increase is

attainable.

If the statements above are

true, which one of the following must on the basis of

them also be

true?

(A)

It

is

only

Quore’s

production

structure

that

makes

it

possible

for

Quore

to

survive

the

transformation of the market.

(B) Quore will not go bankrupt if it achieves a productivity increase of 20 percent over the next

two years.

(C) If the market had not been transformed, Quore would have required no productivity increase

in order to avoid bankruptcy.

(D) Because of the transformation of the market, Quore will achieve a productivity increase of 10

percent over the next two years.

(E) If a 20 percent productivity increase is unattainable for Quore, then it must go bankrupt.

112. Older United

States

automobiles

have

been

identified

as

contributing

disproportionately

to

global air pollution. The requirement in many jurisdictions that automobiles pass emission-control

inspections has had the effect of taking many such automobiles out of service in the United States,

as

they

fail

inspection

and

their

owners

opt

to

buy

newer

automobiles.

Thus

the

burden

of

pollution

such

older

automobiles
