重新输入过了 People who say that Dooney County is flat are clearly
wrong. On flat land, soil erosion by water is not a problem.
Consequently, farmers whose land is flat do not build terraces
to prevent erosion. Ye! I heat that the farms in Dooney County
are dotted with terraces. 12. The author's conclusion in the passage depends on the
assamption that (A) the only cause of soil erosion is water
(B) there are terraces on farmland in Dooney County
which were built to prevent soil erosion
(C) terraces of the kind found on farmland in Dooney
County have been shown to prevent soil erosion
(D) on flat land there is no soil erosion
(E) the only terraces in Dooney County are on
farmland 23. Further evidence of a connection between brain
physiology and psychological states has recently been
uncovered in the form of a correlation between
electroencephalograph patterns and characteristic moods.
A study showed that participants who suffered from
clinical depression exhibited less left frontal lobe activity
than right. while, conversely, characteristically good.
natured participants exhibited grcater left lobe activity.
Thus one's general disposition is a result of the activity
of one's frontal lobe Each of the following. if true, weakens the argument
EXCEPT:
(A) Many drugs prescribed to combat clinical
depression act by causing increased left lobe
activity.
(B) Excessive sleep, a typical consequence of clinical
depression. is known to suppress left lobe
activity.
(C) Frontal lobe activity is not subject to variation the
way general disposition is .
(D) Earlier studies indicated that frontal lobe activity
and emotive states are both caused by activity in
the brain's limbic system.
(E) Social interaction of the kind not engaged in by
most clinically depressed people is known to
stimulate left lobe activity. 17. Cotumnist: It is impossibie for there to be real

smeling. poor der, or seneti factors. The reason is most exinerable on winch one of the wing grounds? (A) The argument fatis to recognize that there may be
convineing statisneai evidence even if indisidual
causes cannot be known.
(B) The argument inappropriatelv presupposes that
what follows a certain pnenomen on was caused
by that phenomenon.
(C) The argument inapprepriately draws a conciusion
about causes of cancer in general from evidence
drawn from a particuiar case of cancer.
(D) The argument ignores other ossible causes of the
increase in cancer rates near the nuclear teactor
complexes.
(E) The argument concindes that a claim about a
causal connection is false on the basis of a lack
of exidence for the claim.
17. Studies of the reliability of eyewithess identifieations
show little correlation between the accuracy of a
witness's account and the confidence the witness has in
the account. Certain factors can increase of undermine a
witness's confidence without altering the accuracy of the
identification. Therefore, police officers are advised to
disaliow suspect llneups in which witnesses can hear one
another identifying suspects.
Which one of the following is a principlw underlying the
advice given to police officers? (A) The confidence people have in what they
remember having seen is affected by their
awareness of what other people claim to have
seen.
(B) Unless an eyewitness is confronted with more
than one suspect at a time, the accuracy of his or
her statements cannot be trusted.
(C) If several eyewitnesses all identify the same
suspect in a lineup, it is more likely that the
suspect committed the crime than if only one
eyewitness identifies the suspect.
(D)  olice officers are more interested in the
confidence witnesses have when testifying than
in the accuracy of that testimony.
(E) The accuracy of an eyewitness account is
doubtful if the eyewitness contradicts what other
eyewitnesses claim to have seen.
21. many weaklings are also cowards, and few
cowards fail to be fools. Thus there must be at least one
persen who is both a weakling and a fool.
The fawed paltern of reasoning in the argument above is
most similar to that in which one of the following? (A) All weasels are carnivores and no carnivores fail
to be nonirerbrvores, so some weasels are
nonherbivores.
(B) Few moralists have the courage to act according
to the principies they profess, and few saints
have the ability to articulate the principles by
which they live, so it follows that few people can
both act like saints and speak like moralists.
(C) Some painters are dancers, since some painters
are musicians, amd some musicians are dancers.
(D) If an act is virtuous. then it is autonomous, for
acts are not virtuous unless they are free, and
acts are not free unless they are autonomous.
(E) A majority of the voting population favors a total
ban, but no one who favors a total ban is
opposed to stiffer tariffs, so at a least one voter is
not opposed to stiffer tariffs.
26. eople ought to take into account a discipline's
btemished origins when assessing the scientific value of
that disipline. Take, for example, chemistry. It must be
considered that many of its landmark results were
obtained by alchemists--a grouo whose superstitions
amd appeals to magic dominated the early developments
of chemical theory.
The reasoning above is most susceptible to criticism
because the author (A) fails to establish that disciplines with
unbliemished origins are serentifically valuable
(B) fails to consider how chemistry's current theories
and practices differ from those of the alchemists
mentioned
(C) uses an example to contradict the principie under
consideration
(D) does not prove that most diseiplines that are not
scientifically valuable have origins that are in
some way suspect
(E) uses the word "discipline" in two different senses |
