Hi,

would you explain me what mistake I did when I answered A or B ? The answer is E

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?

(A) The supply of illegal drugs dropped substantially in 1987.

(B) The price paid for most illegal drugs by the average consumer did 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.

Let's take a look at this one:

Accoding to the supply/demand drugs' prices should have been increased instead of dropped, so we need to find out a reason why it was not the case:

(A) The supply of illegal drugs dropped substantially in 1987. The paragraph is telling you this...not good enought

(B) The price paid for most illegal drugs by the average consumer did not drop substantially in 1987. Out of scope, the parragrap does not talk at all about the average consumer

(C) Domestic production of illegal drugs increased at a higher rate than did the entry of such drugs into the country. Perhaps, but this answer goes to far assuming something we don't knwo for sure, and in GMATland we cannot do that Confused

(D) The wholesale price of a few illegal drugs increased substantially in 1987. Nope it did not

(E) A drop in demand for most illegal drugs in 1987 was not the sole cause of the drop in their wholesale price- YES, there must have been another reason other than the drop in demand of illegal drugs to make the prices drop
