GMAT Sentences:



No. 001


Civil


rights


activists


have


long


argued


that


one


of


the


principal


reasons


the


Blacks,


Hispanics,


and


other


minority groups have difficulty establishing themselves in


business is that they lack access to the sizable orders and


subcontracts that are generated by large companies.



No. 002


Fascination with this ideal has made Americans defy the



Old


World




categories


of


settled


possessiveness


versus



unsettling deprivation, the cupidity of retention


versus


the


cupidity of seizure, a



status quo



defended or attacked.



No. 003


The


nonstarters


were


considered


the


ones


who


wanted


stability,


a


strong


referee


to


give


them


some


position


in


the race, a regulative hand to calm manic speculation; an


authority that can call things to a halt, begin things again


from compensatorily staggered



starting lines.





No. 004



Reform




in


America


has


been


sterile


because


it


can


imagine


no


change


except


through


the


extension


of


this


metaphor


of


a


race,


wider


inclusion


of


competitors,



a


piece of the action,



as it were, for the disenfranchised.



No. 005


We have no pride in our growing interdependence, in the


fact that our system can serve others, that we are able to


help


those


in


need;


empty


boasts


from


the


past


make


us


ashamed


of


our


present


achievements,


make


us


try


to


forget or deny them, move away from them.



No. 006


The traditional view supposes that the upper mantle of the


earth


behaves


as


a


liquid


then


it


is


subjected


to


small


forces for long periods and that differences in temperature


under


oceans


and


continents


are


sufficient


to


produce


convection


in


the


mantle


of


the


earth


with


rising


convection


currents


under


the


mid- ocean


ridges


and


sinking currents under the continents.



No. 007


This


view


may


be


correct:


it


has


the


advantage


that


the


currents


are


driven


by


temperature


differences


that


themselves depend on the position of the continents.



No. 008


The enclosed seas are an important feature of the earth


?


s


surface


and


seriously


require


explanation


because,


in


addition


to


the


enclosed


seas


that


are


developing


at


present


behind


islands


arcs,


there


are


a


number


of


older


ones


of


possibly


similar


origin,


such


as


the


Gulf


of


Mexico, the Black Sea, and perhaps the North Sea.



No. 009


Furthermore, neutrinos carry with them information about


the site and circumstances of their production: therefore,


the


detection


of


cosmic


neutrinos


could


provide


new


information


about


a


wide


variety


of


cosmic


phenomena


and about the history of the universe.



No. 010


Consequently,


nothing


seems


good


or


normal


that


does


not accord with the requirements of the free market.



No. 011


Accordingly,


it


requires


a


major


act


of


will


to


think


of


price-fixing (the determination of prices by the seller) as


both


normal



and having a valuable economic function.



No. 012


In


fact,


price-fixing


is


normal


in


all


industrialized


societies because the industrial system itself provides, as


an


effortless


consequence


of


its


own


development,


the


price-fixing that it requires.



No. 013


That each large firm will act with consideration of its own


needs and thus avoid selling its products for more that its


competitors


?


charge is commonly recognized by advocates


of free-market economic theories.



No. 014


Moreover, those economists who argue that allowing the


free


market


to


operate


without


interference


is


the


most


efficient


method


of


establishing


prices


have


not


considered


the


economies


of


nonsocialist


countries


other


than the United States.



No. 015


Synder,


Daly,


and


Bruns


have


recently


proposed


that


caffeine affects behavior by countering the activity in the


human


brain


of


a


naturally


occurring


chemical


called


adenosine.



No. 016


To


buttress


their


case


that


caffeine


acts


instead


by


preventing adenosine binding, Snyder et al compared the


stimulatory effects of a series of caffeine derivatives with


their ability to dislodge adenosine from its receptors in the


brains of mice.



No. 017


The


problem


is


that


the


compound


has


mixed


effects


in


the


brain,


a


not


unusual


occurrence


with


psychoactive


drugs.



No. 018


Who


would


want


an


unmarked


pot


when


another


was


available


whose


provenance


was


known,


and


that


was


dated


stratigraphically


by


the


professional


archaeologist


who excavated it?



No. 019


Federal


efforts


to


aid


minority


businesses


began


in


the


1960s


when


the


Small


Business


Administration


(SBA)


began


making


federally


guaranteed


loans


and


government-sponsored


management


and


technical


assistance available to minority business enterprises.



No. 020


Recently federal policymakers have adopted an approach


intended


to


accelerate


development


of


the


minority


business


sector


by


moving


away


from


directly


aiding


small


minority


enterprises


and


toward


supporting


larger,


growth-oriented


minority


firms


through


intermediary


companies.



No. 021


MESBIC


?


s


are


the


result


of


the


belief


that


providing


established


firms


with


easier


access


to


relevant


management techniques and more job-specific experience,


as well as substantial amounts of capital, gives those firms


a


greater


opportunity


to


develop


sound


business


foundations that does simply making general management


experience and small amounts of capital available.



No. 022


Most


senior


executives


are


familiar


with


the


formal


decision


analysis


models


and


tools,


and


those


who


use


such


systematic


methods


for


reaching


decisions


are


occasionally


leery


of


solutions


suggested


by


these


methods


which


run


counter


to


their


sense


of


the


correct


course of action.



No. 023


But the debate could not be resolved because no one was


able to ask the crucial questions in a form in which they


could be pursued productively.



No. 024


During the nineteenth century, she argues, the concept of


the



useful



child who contributed to the family economy


gave


way


gradually


to


the


present-day


notion


of


the


useless



child who, though producing no income for, and


indeed


extremely


costly


to,


its


parents,


is


yet


considered


emotionally



pric eless.





No. 025


Well established among segments of the middle and upper


classes


by


the


mid-1800


?


s,


this


new


view


of


childhood


spread


throughout


society


in


the


late-nineteenth


and


early-twentieth


centuries


as


reformers


introduced


child-labor


regulations


and


compulsory


education


laws


predicated


in


part


on


the


assumption


that


a


child


?


s


emotional value made child labor taboo.



No. 026



Expulsion of children from the


?


cash nexus


?




although


clearly


shaped


by


profound


changes


in


the


economic,


occupational,


and


family


structures,




Zelizer


maintains,



was


also


part


of


a


cultural


process


of


?


sacralization


?



of


children


?


s lives.





No. 027


Protecting children from the crass business world became


enormously


important


for


late-nineteenth-century


middle-class


Americans,


she


suggest;


this


sacralization


was


a


way


of


resisting


what


they


perceived


as


the


relentless corruption of human values by the marketplace.



No. 028


The


factors


favoring


unionization


drives


seem


to


have


been either the presence of large numbers of workers, as


in


New


York


City,


to


make


it


worth


the


effort,


or


the


concentration


of


small


numbers


in


one


or


two


locations,


such as a hospital, to make it relatively easy.



No. 029


Individual


entrepreneurs


do


not


necessarily


rely


on


their


kin


because


they


cannot


obtain


financial


backing


from


commercial resources.



No. 030


Since


large


bees


are


not


affected


by


the


spraying


of


Matacil,


these


results


add


weight


to


the


argument


that


spraying


where


the


pollinators


are


sensitive


to


the


pesticide used decreases plant fecundity.



No. 031


The


question


of


whether


the


decrease


in


plant


fecundity


caused


by


the


spaying


of


pesticides


actually


causes


a


decline


in


the


overall


population


of


flowering


plant


species still remains unanswered.



No.032


Although at first the colonies held little positive attraction


for the English



they would rather have stayed home



by


the


eighteenth


century


people


increasingly


migrated


to


America


because


they


regarded


it


as


the


land


of


opportunity.



No. 033


If the competitor can prove injury from the imports



and


that the United States company received a subsidy from a


foreign government to build its plant abroad



the United


States


company


?


s


products


will


be


uncompetitive


in


the


United States, since they would be subject to duties.



No. 034


In


addition


many


ethnologists


at


the


turn


of


the


century


believed that Native American manners and customs were


rapidly disappearing, and that it was important to preserve


for posterity as much information as could be adequately


recorded before the cultures disappeared forever.



No. 035


In such a context, what is recognized as



depen dency



in


Western


psychiatric


terms


is


not,


in


Korean


terms,


an


admission of weakness or failure.



No. 036


And


managers


under


pressure


to


maximize


cost-cutting


will


resist


innovation


because


they


know


that


more


fundamental changes in processes or systems will wreak


havoc with the results on which they are measured.



No. 037


Most


novelists


and


historians


writing


in


the


early


to


mid-twentieth century who considered women in the West,


when


they


considered


women


at


all,


fell


under


Turner


?


s


spell.



No. 038


In


addition,


the


ideal


of


six


CEO


?


s


(female


or


male)


serving on the board of each of the largest corporations is


realizable only if every CEO serves on six board.



No. 039


Increasingly,


historians


are


blaming


diseases


imported


from the Old World for the staggering disparity between


the


indigenous


population


of


America


in


1492




new


estimates


of


which


soar


as


high


as


100


million,


or


approximately one-sixth of the human race at that time




and the few million full-blooded Native Americans alive


at the end of the nineteenth century.



No. 040


Virgin-soil


epidemics


are


those


in


which


the


populations


at risk have had no previous contact with the diseases that


strike


them


and


are


therefore


immunologically


almost


defenseless.



No. 041


Spanish tribute records




The evidence provided by the


documents


of


British


and


French


colonies


is


not


as


definitive


because


the


conquerors


of


those


areas


did


not


establish


permanent


settlements


and


begin


to


keep


continuous


records


until


the


seventeenth


century,


by


which


time


the


worst


epidemics


had


probably


already


taken place.



No. 042


Unfortunately,


the


documentation


of


these


and


other


epidemics


is


slight


and


frequently


unreliable,


and


it


is


necessary


to


supplement


what


little


we


do


know


with


evidence from recent epidemics among Native Americans.



No. 043


Scientists have begun to suspect that this intergalactic gas


is


probably


a


mixture


of


gases


left


over


from


the



big


bang



when the galaxies were formed and gas was forced


out of galaxies by supernova explosions.



No. 044


He noted that the wavelengths of the radiation emitted by


a gas would change as the gas cooled, so that as the gas


flowed into the galaxy and became cooler, it would emit


not x-rays, but visible light, like that which was captured


in the photographs.



No. 045


Transported


outside


the


nucleus


to


the


cytoplasm,


the


mRNA


is


translated


into


the


protein


it


encodes


by


an


organelle


known


as


a


ribosome,


which


strings


together


amino


acids


in


the


order


specified


by


the


sequence


of


elements in the mRNA molecule.



No. 046


However,


recent


investigations


have


shown


that


the


concentrations


of


most


mRNA


?


s


correlate


best,


not


with


their


synthesis


rate,


but


rather


with


the


equally


variable


rates at which cells degrade the different mRNA


?


s in their


cytoplasm.



No. 047


If a cell degrades both a rapidly and a slowly synthesized


mRNA


slowly,


both


mRNA


?


s


will


accumulate


to


high


levels.



No. 048


For


instance,


the


mass-production


philosophy


of


United


States automakers encouraged the production of huge lots


of


cars


in


order


to


utilize


fully


expensive,


component-specific


equipment


and


to


occupy


fully


workers who have been trained to execute one operation


efficiently.



No. 049


Japanese automakers chose to make small-lot production


feasible


by


introducing


several


departures


from


United


States


practices,


including


the


use


of


flexible


equipment


that


could


be


altered


easily


to


do


several


different


production


tasks


and


the


training


of


workers


in


multiple


jobs.



No. 050


Automakers


could


schedule


the


production


of


different


components


or


models


on


single


machines,


thereby


eliminating


the


need


to


store


the


buffer


stocks


of


extra


components


that


result


when


specialized


equipment


and


workers are kept constantly active.



No. 051


In


recent


studies,


however,


we


have


discovered


that


the


production


and


release


in


brain


neurons


of


the


neurotransmitter


serotonin


(neurotransmitters


are


compounds


that


neurons


use


to


transmit


signals


to


other


cells) depend directly on the food that the body processes.



No. 052


Our first studies sought to determine whether the increase


in serotonin observed in rats given a large injection of the


amino


acid


tryptophan


might


also


occur


after


rats


ate


meals that change tryptophan levels in the blood.



No. 053


The consumption of protein increases blood concentration


of the other amino acids much more, proportionately, than


it does that of tryptophan.



No. 054


The revisionist view of Jim Crow legislation grew in part


from


the


research


that


Woodward


had


done


for


the


NAACP legal campaign during its preparation for


Brown


v. Board of Education.




No. 055


Woodward


confessed


with


ironic


modesty


that


the


first


edition



had begun to suffer under some of the handicaps


that


might


be


expected


in


a


history


of


the


American


Revolution published in 1776.





No. 056


Yet,


like


Paine,


Woodward


had


an


unerring


sense


of


the


revolutionary


moment,


and


of


how


historical


evidence


could


undermine


the


mythological


tradition


that


was


crushing the dreams of new social possibilities.



No. 057


Joseph


Glarthaar


?


s


Forged


in


Battle



is


not


the


first


excellent study of Black soldiers and their White officers


in


the


Civil


War,


but


it


uses


more


soldiers


?



letters


and


diaries



including rare material from Black soldiers



and


concentrates


more


intensely


on


Black-While


relations


in


Black regiments that do any of its predecessors.



No. 058


While


perhaps


true


of


those


officers


who


joined


Black


units


for


promotion


or


other


self-serving


motives,


this


statement


misrepresents


the


attitudes


of


the


many


abolitionists who became officers in Black regiments.



No. 059


Moreover,


arguments


pointing


out


the


extent


of


both


structural


and


functional


differences


between


eukaryotes


and


true


bacteria


convinced


many


biologists


that


the


precursors of the eukaryotes must have diverged from the


common ancestor before the bacteria arose.



No. 060


New


techniques


for


determining


the


molecular


sequence


of


the


RNA


of


organisms


have


produced


evolutionary


information


about


the


degree


to


which


organisms


are


related,


the


time


since


they


diverged


from


a


common


ancestor,


and


the


reconstruction


of


ancestral


versions


of


genes.



No. 061


These


techniques


have


strongly


suggested


that


although


the


true


bacteria


indeed


form


a


large


coherent


group,


certain


other


bacteria,


the


archaebacteria,


which


are


also


prokaryotes and which resemble true bacteria, represent a


distinct


evolutionary


branch


that


far


antedates


the


common ancestor of all true bacteria.



No. 062


The new tax law allowed corporations to deduct the cost


of


the


product


donated


plus


half


the


difference


between


cost


and


fair


market


selling


price,


with


the


proviso


that


deductions cannot exceed twice cost.



No. 063


Unfortunately, emancipation has been less profound than


expected, for not even industrial wage labor has escaped


continued sex segregation in the workplace.



No. 064


To


explain


this


unfinished


revolution


in


the


status


of


women, historians have recently begun to emphasize the


way a prevailing definition of femininity often determines


the


kinds


of


work


allocated


to


women,


even


when


such


allocation is inappropriate to new conditions.



No. 065


For instance, early textile-mill entrepreneurs, in justifying


women


?


s


employment


in


wage


labor,


made


much


of


the


assumption that women were by nature skillful at detailed


tasks and patient in carrying out repetitive chores; the mill


owners thus imported into the new industrial order hoary


stereotypes


associated


with


the


homemaking


activities


they presumed to have been the purview of women.



No. 066


More remarkable than the origin has been the persistence


of such sex segregation in twentieth-century industry.



No. 067


According


to


a


recent


theory,


Archean-age


gold-quartz


vein systems were formed over two billion years ago from


magmatic


fluids


that


originated


from


molten


granitelike


bodies deep beneath the surface of the Earth.



No. 068


However,


none


of


these


high-technology


methods


are


of


any value if the sites to which they are applied have never


mineralized,


and


to


maximize


the


chances


of


discovery


the


explorer


must


therefore


pay


particular


attention


to


selecting


the


ground


formations


most


likely


to


be


mineralized.



No. 069


In


order


for


the


far- ranging


benefits


of


individual


ownership


to


be


achieved


by


owners,


companies,


and


countries,


employees


and


other


individuals


must


make


their own decisions to buy, and they must commit some of


their own resources to the choice.



GRE Sentences:



No. 001


That


sex


ratio


will


be


favored


which


maximizes


the


number of descendants an individual will have and hence


the number of gene copies transmitted.



No. 002


Hardy


?


s


weakness


derived


from


his


apparent


inability


to


control


the


comings


and


goings


of


these


divergent


impulses


and


from


his


unwillingness


to


cultivate


and


sustain the energetic and risky ones.



No. 003


Virginia


Woolf


?


s


provocative


statement


about


her


intentions


in


writing


Mrs.


Dalloway



has


regularly


been


ignored by the critics, since it highlights an aspect of her


literary interests very different from the traditional picture


of the



p oetic



novelist concerned with examining states


of


reverie


and


vision


and


with


following


the


intricate


pathways of individual consciousness.



No. 004


As


she


put


it


in


The


Common


Reader


,



It


is


safe


to


say


that


not


a


single


law


has


been


framed


or


one


stone


set


upon another because of anything Chaucer said or wrote;


and


yet,


as


we


read


him,


we


are


absorbing


morality


at


every pore.





No. 005


With the conclusion of a burst of activity, the lactic acid


level is high in the body fluids, leaving the large animal


vulnerable


to


attack


until


the


acid


is


reconverted,


via


oxidative metabolism, by the liver into glucose, which is


then


sent


(in


part)


back


to


the


muscles


for


glycogen


resynthesis.



No. 006


Although


Gutman


admits


that


forced


separation


by


sale


was


frequent,


he


shows


that


the


slaves


?



preference,


revealed


most


clearly


on


plantations


where


sale


was


infrequent, was very much for stable monogamy.



No. 007


Gutman argues convincingly that the stability of the Black


family


encouraged


the


transmission


of




and


so


was


crucial


in


sustaining




the


Black


heritage


of


folklore,


music,


and


religious


expression


from


one


generation


to


another, a heritage that slaves were continually fashioning


out of their African and American experiences.



No. 008


This preference for exogamy, Gutman suggests, may have


derived


from


West


African


rules


governing


marriage,


which,


though


they


differed


from


one


tribal


group


to


another,


all


involved


some


kind


of


prohibition


against


unions with close kin.



No. 009


His


thesis


works


relatively


well


when


applied


to


discrimination against Blacks in the United States, but his


definition


of


racial


prejudice


as



racially-based


negative


prejudgements


against


a


group


generally


accepted


as


a


race


in


any


given


region


of


ethnic


competition,




can


be


interpreted as also including hostility toward such ethnic


groups


as


the


Chinese


in


California


and


the


Jews


in


medieval Europe.



No. 010


Such


variations


in


size,


shape,


chemistry,


conduction


speed,


excitation


threshold,


and


the


like


as


had


been


demonstrated


in


nerve


cells


remained


negligible


in


significance for any possible correlation with the manifold


dimensions of mental experience.



No. 011


It


was


possible


to


demonstrate


by


other


methods


refined


structural differences among neuron types; however, proof


was lacking that the quality of the impulse or its condition


was


influenced


by


these


differences,


which


seemed


instead


to


influence


the


developmental


patterning


of


the


neural circuits.



No. 012


Although qualitative variance among nerve energies was


never


rigidly


disproved,


the


doctrine


was


generally


abandoned


in


favor


of


the


opposing


view,


namely,


that


nerve


impulses


are


essentially


homogeneous


in


quality


and are transmitted as



common currency



throughout the


nervous system.



No. 013


Other


experiments


revealed


slight


variations


in


the


size,


number,


arrangement,


and


interconnection


of


the


nerve


cells,


but


as


for


as


psychoneural


correlations


were


concerned, the obvious similarities of these sensory fields


to each other seemed much more remarkable than any of


the minute differences.



No. 014


Although


some


experiments


show


that,


as


an


object


becomes


familiar,


its


internal


representation


becomes


more holistic and the recognition process correspondingly


more parallel, the weight of evidence seems to support the


serial hypothesis, at least for objects that are not notably


simple and familiar.



No. 015


In large part as a consequence of the feminist movement,


historians have focused a great deal of attention in recent


years on determining more accurately the status of women


in various periods.



No. 016


If


one


begins


by


examining


why


ancients


refer


to


Amazons,


it


becomes


clear


that


ancient


Greek


descriptions of such societies were meant not so much to


represent


observed


historical


fact




real


Amazonian


societies




but


rather


to


offer



moral


lessons




on


the


supposed outcome of women


?


s rule in their own society.



No. 017


Thus,


for


instance,


it


may


come


as


a


shock


to


mathematicians to learn that the


Schrodinger


equation for


the hydrogen atom is not a literally correct description of


this atom, but only an approximation to a somewhat more


correct equation taking account of spin, magnetic dipole,


and relativistic effects; and that this corrected equation is


itself only an imperfect approximation to an infinite set of


quantum field- theoretical equations.



No. 018


The


physicist


rightly


dreads


precise


argument,


since


an


argument that is convincing only if it is precise loses all


its


force


if


the


assumptions


on


which


it


is


based


are


slightly changed, whereas an argument that is convincing


though


imprecise


may


well


be


stable


under


small


perturbations of its underlying assumptions.



No. 019


However,


as


they


gained


cohesion,


the


Bluestockings


came


to


regard


themselves


as


a


women


?


s


group


and


to


possess


a


sense


of


female


solidarity


lacking


in


the


salonnieres


,


who


remained


isolated


from


one


another


by


the primacy each held in her own salon.



No. 020


As


my


own


studies


have


advanced,


I


have


been


increasingly


impressed


with


the


functional


similarities


between


insect


and


vertebrate


societies


and


less


so


with


the


structural


differences


that


seem,


at


first


glance,


to


constitute such an immense gulf between them.



No. 021


Although


fiction


assuredly


springs


from


political


circumstances, its authors react to those circumstances in


ways other than ideological, and talking about novels and


stories


primarily


as


instruments


of


ideology


circumvents


much of the fictional enterprise.



No. 022


Is


this


a


defect,


or


are


the


authors


working


out


of,


or


trying to forge, a different kind of aesthetic?



No. 023


In


addition,


the


style


of


some


Black


novels,


like


Jean


Toomer


?


s


Cane


,


verges


on


expressionism


or


surrealism;


does


this


technique


provide


a


counterpoint


to


the


prevalent theme that portrays the fate against which Black


heroes


are


pitted,


a


theme


usually


conveyed


by


more


naturalistic modes of expression?



No. 024


Black Fiction surveys a wide variety of novels, bringing


to


our


attention


in


the


process


some


fascinating


and


little-known


works


like


James


Weldon


Johnson
