Answer Explanations

Reading 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.
