3. b. The survey statistics demonstrate that most baby boomers will keep working, so the Social Securitysystem will not encounter a sudden massive strain as baby boomers reach the retirement age. Choice ais incorrect because although the number of baby boomers is cited (80,000,000), no other figure iscited in comparison. One statistic from the survey suggests that many baby boomers have not plannedwell 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 eis incorrect forthe same reason.
