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?
For the population as a whole, annual alcohol consumption is no lower now than it was in 1990.
Alcohol consumption away from home, for example in bars and restaurants, is much lower among people under 21 than it was in 1990.
The proportion of people under 21 who own a car is higher now than it was in 1990.
Alcohol consumption is lower among people under 21 than among adults in most other age-groups.
Alcohol-related deaths among people over 21 have increased since 1990.
自从1990年合法饮酒年龄提高到21岁以后，21岁以下人群中酒驾引起的死亡显著降低了。但是研究显示这些人饮酒量和1991年以前一样多。问explain
choice b, 21岁以下年轻人在家之外环境的饮酒（餐厅、酒吧等）比起1991年以前降低了。correct，在外饮酒减少也就因此减少酒驾的可能性，但依然可能保证总体饮酒量不变
