问题 A public-service advertisement advises that people who have consumed alcohol should not drive until they can do so safely. In a hospital study, however, subjects questioned immediately after they consumed alcohol underestimated the time necessary to regain their driving ability. This result indicates that many people who drink before driving will have difficulty following the advertisement’s advice. Which of the following, if true, most strongly supports the argument above?
选项 A、Many people, if they plan to drink alcohol, make arrangements beforehand for a nondrinker to drive them home.
B、The subjects in the hospital study generally rated their abilities more conservatively than would people drinking alcohol outside a hospital setting.
C、Some people refrain from drinking if they will have to drive to get home afterward.
D、The subjects in the hospital study were also questioned about the time necessary to regain abilities that do not play an important role in driving safely.
E、Awareness of the public-service advertisement is higher among the general population than it was among the subjects in the hospital study.
答案B
解析 本题典型的“B，A”型支持，由一个study而得出一个结论，那么支持最重要的是支持结论“在开车前喝酒的人很多在遵从广告的建议方面有困难。医院里的被调查者低估了他们恢复开车能力所必需的时间，如果这些人相对那些在医院环境之外喝酒的人来说更加保守，正如(B)所说，那么所有开车之前喝酒的人都会低估他们恢复开车能力所必需的时间，所以他们在遵从广告建议方面有困难。因此(B)正确。
