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.
在B地，1900年前的合法喝酒年龄是18岁，之后改为了21岁。
现在18-21岁中因喝酒而造成的交通死亡人数（Alcohol-related traffic deaths）↓，但酒的消费量不变（）drink just as much alcohol as 。
解释：
B 近年来在酒吧等外边喝酒的21岁以下的人数少于1900年以前的。 （√）不出去喝酒→不开车→出车祸死亡的人 ↓
C 21岁以下有汽车的人数比例增加。（×）与文意相反，汽车增加应该导致的是事故增加↑，而不是减少。
