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.
80. 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.
81. The argument in the passage would be most seriously weakened if it were true that
(A) in 1987 smugglers of illegal drugs, as a group, had significantly more funds at their disposal than did the country’s customs agents
(B) domestic production of illegal drugs increased substantially in 1987
(C) the author’s statements were made in order to embarrass the officials responsible for the drug-control program
(D) in 1987 illegal drugs entered the country by a different set of routes than they did in 1986
(E) the country’s citizens spent substantially more money on illegal drugs in 1987 than they did in 1986.
