In Berinia, the age at which people could begin to drink alcohol legally used to be 18. In 1990, in an attempt to reduce alcohol consumption and thereby to reduce alcohol-related traffic deaths among Berinians under 21, the legal drinking age was raised to 21. Alcohol-related traffic deaths among people under 21 have decreased significantly since 1990. 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 than
it 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.
请教思路！
Is the answer B?
can any one helps us to explain this question?
tks a lot.
Is the answer B? If it is, then
A." For the population as a whole..." is not relevant with main topic.
B helps explain why "...Alcohol-related traffic deaths among people under 21 have decreased significantly since 1990. Nevertheless, surveys show that people in that age-group drink just as much alcohol as they did before 1990. ", since the chance that people are getting involved in car accidents on their way home or whatever after drinking is much lower.
C seems to suggest that more young people might have a chance to get involved in car accidents.
D.& E both are not relevant.
