Verb form 2 – VERBAL SECTION PRACTICE TEST –75. When a normally functioning immune system attacks a nonself molecule, the system has the ability to “remember” the specifics of the foreign body, and upon subsequent encounters with the same species of molecules, it reacts accordingly. a. it reacts b. the foreign body reacts c. the molecules react d. the immune system reacts e. the species react A nswer ExplanationsReading Comprehension 1. d. This choice offers the best title for the passage, which explains why the “worriers in Washington” may have nothing to fear after all. Choice a is incorrect because the passage is not about the relation- ship between the AARP and Social Security or the AARP’s position on Social Security issues. Choice b is incorrect because the passage actually argues the opposite: that most baby boomers will continue to pay into Social Security long after the traditional age of retirement. Choice c is true, but it is just one specific fact cited within the passage to support the main idea. Choice e is also true, but the passage explains why the economists’ fears are unfounded. 2. c. The AARP study cited in the third paragraph reveals that 87% of the baby boomers surveyed “planned to continue working for pay” once they reach retirement age. The passage does not state that the government raised the retirement age (choice a). Choices b and e are incorrect because the AARP survey also notes that “between 25% and 44% of respondents reported they are not financially pre- pared to retire,” which means they will need supplemental income. A desire to remain active in their community (choice d) is one of the reasons many baby boomers will continue to work, but it is the fact that they will continue to work (not why they will continue to work) that allays the fear of a bank- rupt system. 3. b. The survey statistics demonstrate that most baby boomers will keep working, so the Social Security system will not encounter a sudden massive strain as baby boomers reach the retirement age. Choice a is incorrect because although the number of baby boomers is cited (80,000,000), no other figure is cited in comparison. One statistic from the survey suggests that many baby boomers have not planned well for retirement (choice c), but several other statistics are also cited, so this cannot be the main pur- pose. The passage states that the survey was designed in part to measure baby boomers’ optimism (choice d), but the passage does not cite results of questions in that category. Choice e is incorrect for the same reason. 193 – VERBAL SECTION PRACTICE TEST –4. a. The survey found that a quarter to nearly a half of all respondents planned to keep working because “they are not financially prepared to retire.” This suggests that many baby boomers do not have adequate savings. Nothing in the survey results suggests a fear of retirement (choice b). Also, nothing in the passage suggests that baby boomers are unaware of the cost of retirement (choice c). The passage does not assess how realistic baby boomers’ goals are (choice d) and makes no reference to politicians (choice e) other than the vague “worriers in Washington,” a group that could include econ- omists, lobbyists, and many other kinds of people.5. c. Although the passage does demonstrate the fragility of an endangered species (choice a) and the importance of effective wildlife management (choice b), the main goal is to argue that mixing species is the wrong way to attempt to preserve an endangered species. This is expressed clearly in the final paragraph: “We cannot and should not create genetically mixed species as a means of achieving a com- promise between the needs of development and a species’ survival.” The passage does show that the mixing of species was successful (choice d), but the passage criticizes this point. The author is critical of land development in areas with specific endangered species, but this is not the focus of the passage, so choice e is incorrect.6. b. The main idea of the passage is that efforts to preserve species through interbreeding will only backfire, pushing a particular endangered species farther down the road to extinction. The passage’s statistics show how the interbreeding has accomplished this in the case of the Florida panther. The Texas panther is not described, so choice a is incorrect. The author does not attack general wildlife protection policies — indeed, no policies are mentioned, only the specific handling of this panther pop- ulation — so choice c is incorrect. Human encroachment was a main threat to the panthers (choice d), but the author did not discuss how encroachment harmed the ...
