Q28:
In Berinia, the age at which people could begin to drink alcohol legally used to be 18. In1990, in an attempt to reduce alcohol consumption and thereby to reduce alcohol-relatedtraffic deaths among Berinians under 21, the legal drinking age was raised to 21.Alcohol-related traffic deaths among people under 21 have decreased significantly since1990. Nevertheless, surveys show that people in that age-group drink just as much alcohol as they did before 1990.
Which of the following, if true of Berinia, most helps to resolve the apparent discrepancy?
A. For the population as a whole, annual alcohol consumption is no lower now thanit was in 1990.
B. Alcohol consumption away from home, for example in bars and restaurants, is much lower among people under 21 than it was in 1990.
C. The proportion of people under 21 who own a car is higher now than it was in 1990.
D. Alcohol consumption is lower among people under 21 than among adults in most other age-groups.
E. Alcohol-related traffic deaths among people over 21 have increased slightly since 1990.
ANS:B
但我不能了解最後一句話的結論跟原文之間有什麼discrepancy?感覺上B的答案好像是一種假設,但除了B沒有更好的答案了
