　　9. In recent years, there has been a dramatic decline in
　　the population of the shrike, a predatory bird that
　　inhabits flat land, such as farms and pastures. Some
　　ornithologists hypothesize that this decline is due to
　　the introduction of new, more effective pesticides to
　　control the insect species on which shrikes prey.
　　The answer to which of the following questions is
　　NOT relevant to evaluating the ornithologists'
　　hypothesis?
　　(A) Was there a decline in the shrike population
　　before the new pesticides were first used?
　　(B) Have shrike populations declined significantly
　　in those habitats where the new pesticides have
　　not been used?
　　(C) Have the new pesticides more significantly
　　reduced the population of insect species on
　　which shrikes prey than did the pesticides previously
　　used?
　　(D) Are insects that have consumed the new pesti-
　　cides more toxic to the shrikes that eat those
　　insects than were insects that consumed the
　　less effective pesticides?
　　(E) Are the new pesticides considered by most
　　people to be less harmful to the environment
　　than the old pesticides were considered to be?
　　10. Census data for Prenland show that unmarried
　　Prenlandic men in their thirties outnumber unmarried
　　Prenlandic women in that age group by about ten to
　　One. Most of these men do wish to marry. Clearly,
　　however, unless many of them marry women who
　　are not Prenlandic, all but a minority will remain
　　unmarried.
　　The argument makes which of the following assump-
　　tions?
　　(A) Emigration from Preland is more common
　　among women than among men.
　　(B) A greater proportion of Prelandic women
　　in their thirties than of Prenlandic men of the
　　same age would prefer to remain unmarried.
　　(C) It is unlikely that many of these unmarried
　　Prenlandic men will marry women more than
　　a few years older than themselves.
　　(D) Prenland has a high rate of divorce.
　　(E) Most of the unmarried Prenlandic men are
　　unwilling to marry women who are not
　　Prenlandic.
　　11.Certain extremely harmful bacteria found only in
　　sewage are difficult to detect directly. Testing for
　　E. coli, an easily detected and less harmful type of
　　bacteria, in ocean water would be a reliable way of
　　determining whether or not these more harmful bac-
　　teria are present, since ocean water contains E. Coli
　　only if the water is contaminated with sewage that
　　contains the harmful bacteria.
　　Which of the following, if true, most seriously
　　weakens the argument?
　　(A) There are many different strains of the E. coli
　　bacteria, and only some of these strains are
　　harmful.
　　(B) Some types of bacteria found in sewage are
　　neither disease-causing nor difficult to detect
　　directly.
　　(C) Some of the types of bacteria found in sewage
　　along with E. coli are not harmful to people
　　unless the bacteria are ingested in large quantities.
　　(D) E. coli dies out much more quickly than some of
　　the more harmful bacteria found in sewage and
　　then can no longer be easily detected.
　　(E) Some of the types of bacteria found in sewage
　　along with E. coli reproduce at a slower rate
　　than E. coli.

　　Q, R, T and W-will appear on the first seven pages-numbered
　　consecutively from page 1 through page 7-of an exhibit catalog.
　　Each page will contain exactly one of the photographs. The ordering
　　of the photographs in the catalog is governed by the following

　　23.The organizers of tomorrow's outdoor concert
　　announced that it will go on tomorrow on schedule
　　unless bad weather is forecast or too few advance
　　tickets are sold. If the concert is canceled, refunds
　　will be made to ticket holders. Since some ticket
　　holders have already been issued refunds even though
　　more than enough advance tickets were sold, it must
　　be the case that bad weather is forecast.
　　Which of the following is an error of reasoning con-
　　tained in the argument?
　　(A) It proceeds as if a condition, which by itself is
　　enough to guarantee a certain result, is the only
　　condition under which that result would occur.
　　(B) It bases a conclusion that is known to require
　　two conditions on evidence that bears on only
　　one of those conditions.
　　(C) It explains one event as being caused by another
　　event, even though both events must actually
　　have been caused by some third, unidentified
　　event.
　　(D) It treats evidence for the absence of one condi-
　　tion under which a circumstance would occur
　　as conclusive evidence that that circumstance
　　will not occur.
　　(E) Evidence given to support the conclusion actually
　　undermines it.
　　24. Although the prevailing supposition has been that it is
　　too hot for microorganisms to survive deep below the
　　Earth's surface, some scientists argue that there are
　　living communities of microorganisms there that have
　　been cut off from surface life for millions of years.
　　These scientists base their argument on the discovery
　　of living microorganisms in samples of material that
　　were taken from holes drilled as deep as 1.74 miles.
　　The scientists' argument depends on which of the fol-
　　lowing assumptions?
　　(A)The microorganisms brought up were of a
　　species that is related to those previously
　　known to science.
　　(B)No holes have been drilled into the Earth's
　　surface to a distance deeper than 1.74 miles
　　(C)The microorganisms did not come from surface
　　soil that came into contact with the drilling
　　equipment.
　　(D) The stratum from which the samples came has
　　been below the surface of the Earth ever since
　　the Earth came into existence.
　　(E) The temperature at the bottom of the holes drilled
　　was not significantly hotter than that of the
　　hottest spots on the Earth's surface.
　　25. For 20 years all applicants for jobs as technicians at
　　EquipCorp were required to demonstrate that they could
　　operate and repair the machinery that was central to
　　EquipCorp's manufacturing business. Now, however,
　　that particular machinery is obsolete, and very different
　　machinery fills the central role. Therefore, the old
　　requirement is no longer a useful method for evaluating
　　whether applicants for jobs as technicians at EquipCorp
　　have the skills necessary for the job.
　　Which of the following, if true, most strengthens the
　　argument?
　　(A) The machinery that is now obsolete was used by a
　　large number of manufacturing companies before
　　it became obsolete.
　　(B) Among the people already holding jobs as tech-
　　nicians at Equip Corp, those who are most skillful
　　at operating the new machinery had been some of
　　the least skillful at operating the old machinery
　　(C) Most people applying for jobs as technicians today
　　have much broader skills than did people applying
　　for jobs as technicians 20 years ago.
　　(D) The skills required to operate and repair the
　　obsolete machinery are useful in operating and
　　maintaining many other types of machinery at
　　EquipCorp that are not obsolete.
　　(E) Much of the machinery that EquipCorp now uses in
　　manufacturing is very likely to become obsolete
　　within the next 20 years.
