the program to control the entry of illegal drugs into the country was a failure in 1987. if the program had been successful, the wholesale price of most illegal drugs would not have dropped substantially in 1987.
the argument in the passage depends on which of the following assumptions?
1)the supply of illegal drugs dropped substantially in 1987.
2)the price paid for most illegal drugs by the average consumer did not drop substantially in 1987.
3)domestic production of illegal drugs increased at a higher rate than did the entry of such drugs into the country.
4)the wholesale price of a few illegal drugs increased substantially in 1987.
5)a drop in demand for most illegal drugs in 1987 was not the sole cause of the drop in their wholesale price.
这里是说对非法药物的控制进口失败了，如果没有失败，那么大部分非法药物不会降价。
选E的吧？
就是说需求下降不是价格下降的唯一原因。
e
program没有成功的判定标准是wholesale price of most illegal drugs 下降与否。成功将不会下降，下降意味着没成功，也就是控制了进口。注意这成功只是限制进口的成功。
奇怪了，那为什么成功了总销量还没下降呢？按常理，成功了吸毒的人应该少，销量也应该下降啊。那说明是销量下降是不因为需求量下降了。也就是e。别的原因比如进口量多了，供应商竞争激烈，反而降价了，所以总销量下降了。（a相反，b相反，c无关，d无关。）
e指出了需求量和价格的矛盾之处，虽然没具体说明，但是有

请注意这里的wholesale price不是总销量而是指批发的价格
