9. Paleontologists have discovered fossils of centipedes that are 414 million years older than the earliest land-dwelling animals previously identified. The paleontologists are confident that these centipedes were discovered in rock that also contained fossilized remained of animals known to be water-dwelling.
The paleontologists¡¯ view would be LEAST
(A) The legs of the fossilized centipedes were particularly suited to being a means of locomotion on land.
(B) All of the centipedes that had previously been discovered were land dwellers.
(C) The rock in which the fossilized centipedes were found was formed from mud flats that were occasionally covered by river water.
(D) Fossils of the earliest land-dwelling animals that had previously been identified were found in rock that did not contain fossilized remains of water-dwelling animals.
(E) Fossils of spiders with respiratory systems adapted only to breathing air were found in the same rock as the centipede fossils.

13. Editorial: In rejecting the plan proposed by parliament to reform the electoral process, the president clearly acted in the best interests of the nation. Anyone who thinks otherwise should remember that the president made this decision knowing it would be met with fierce opposition at home and widespread disapproval abroad. All citizens who place the nation’s well-being above narrow partisan interests will applaud this courageous action.
The reasoning in the editorial is in error because
(A) it confused a quality that is merely desirable in a political leader with a quality that is essential to effective political decision-making
(B) it fails to distinguish between evidence concerning the courage required to make a certain decision and evidence concerning the wisdom of making that decision
(C) it ignores the likelihood that many citizens have no narrow partisan interest in the proposed
(D) it overlooks the possibility that there was strong opposition to the parliament’s plan among members of the president's among members of the president's own party
(E) it depends on the unwarranted assumption that any plan proposed by a parliament will necessarily serve only narrow partisan interests

19. Fares on the city-run public buses in Greenville are subsidized by city tax revenues, but among the beneficiaries of the low fares are many people who commute from outside the city to jobs in Greenville.Some city councilors argue that city taxes should be used primarily to benefit the people who pay them, and
therefore that bus fares should be raised enough to cover the cost of the service.
Each of the following, if true, would weaken the argument advanced by the city councilors EXCEPT:
(A) Many businesses whose presence in the city is beneficial to the city’s taxpayers would relocate outside the city if public-transit fare were more expensive.
(B) By providing commuters with economic incentives to drive to work, higher transit fares would worsen air pollution in Greenville and increase the cost of maintaining the city’s streets.
(C) Increasing transit fares would disadvantage those residents of the city whose low incomes make them exempt from city taxes, and all city councilors agree that these residents should be able to take advantage of city-run services.
(D) Voters in the city, many of whom benefit from the low transit fares are strongly opposed to increasing local taxes.
(E) People who work in Greenville and earn wages above the nationally mandated minimum all pay the city wage tax of 5 percent.

20. Government official: Clearly, censorship exists if we, as citizens, are not allowed to communicate what we are ready to communicate at our own expense or if other citizens are not permitted access to our communications at their own expense. Public unwillingness to provide funds for certain kinds of scientific,scholarly, or artistic activities cannot, therefore, be described as censorship.
The flawed reasoning in the government official’s argument is most parallel to that in which one of the following?
(A) All actions that cause unnecessary harm to others are unjust: so if a just action causes harm to others that action must be necessary.
(B) Since there is more to good manners than simply using polite forms of address, it is not possible to say no first meeting a person whether or not that person has good manners.
(C) Acrophobia, usually defined as a morbid fear of heights, can also mean a morbid fear of sharp objects.Since both fears have the same origin.
(D) There is no doubt that a deed is heroic if the doer risks his or her own life to benefit another person. Thus an action is not heroic if only thing it endangers is the reputation of the doer.
(E) Perception of beauty in an object is determined by past and present influences on the mind of the beholder. Thus on object can be called beautiful, since not everyone will see beauty in it.
answer my choice:A

24. The body of anyone infected by virus X will, after a week, produce antibodies to fight the virus: the antibodies will increase in number for the next year or so. There is now a test that reliably indicates now many antibodies are present in a person’s body. If positive, this test can be used during the first year of infection to estimate to within a month how long that person has had the virus.
Which one of the following conclusions is best supported by the statements above?
(A) Antibodies increase in number only until they have defeated the virus.
(B) Without the test for antibodies, there is no way of establishing whether a person has virus X.
(C) Antibodies are produced only for viral infections that cannot be fought by any other body defenses.
(D) If a person remains infected by virus X indefinitely, there is no limit to the number of antibodies that can be present in the person’s body.
(E) Anyone infected by virus X will not a time fail to exhibit infection if tested by the antibody test
answer:E
