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 Berinlans 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 deaths among people over 21 have increased since 1990.
