标题: 陈向东假设例题21

21. The program to control the entry of illegal drugs into the country was failure in 1987. If the program had been successful, the wholesale price of most illegal drugs would not have dropped substantially in 1987.

The arguement in the passage depends on which of the following assumptions?

A. The supply of illegal drugs dropped substantially in 1987

B. The price paid for most illegal drugs by the average consumer didi not drop substantially in 1987

C. Domestic production of illegal drugs increased at a higher rate than did the entry of such drugs into the country

D. The wholesale price of a few illegal drugs increased substantially in 1987

E. A drop in demand for most illegal drugs in 1987 was not the sole cause of the drop in their wholesale price

我想来想去都很难清晰得把错误答案给排除,大家帮我怎么去排除错误的选项吧

文章意在说“如果供给减少,那么价格不会下降”。价格是由供给和需求决定的。

a 供给减少(没有说需求)

b 一般的消费者买药的价格没有下降(和文章矛盾)

c 国内生产的违禁药物产量增长率比违禁药物进口高 (供给过剩,没有说需求)

d 一些违禁药物的价格上涨(文章说大部分的违禁药物,这个说的是少数违禁药物的价格,文章未提。此外,文章的方向是指的价格下降,本选项与文章的方向矛盾)

e 需求下降不是价格下降的唯一原因(说明价格下降还有其他的原因,即供给的原因)

my answer is E
