T-4-Q28~~一道逻辑题求指点分析....!!!
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 help 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.
我选的D...答案是B
我是这么想的：
1、举措的目的是：减少21岁以下人的就精消耗&减少酒精相关交通事故的21岁人的死亡
2、21岁相关的死亡人数下降 说明 举措有效
3、如果举措有效 那么 21岁喝的酒应该减少 但是实际上却没有减少
那么D说 21的消耗比其他年龄段都少 能不能认为这样：21岁以下的人的消耗没有减少是因为整体消耗增加（由21岁以下的消耗比别的少），实际上比较而言，21岁以下的还是少了...
对于答案B，找不到可以解决矛盾的原因....
