题目:
The number of citations issued to convenience stores for selling tobacco products to minors has dramatically decreased in recent years. Between the years 1985-1990, a total of 5,511 citations were issued to convenience stores for this infraction. For the period 1990-1995, however, only 3,189 citations were issued. These statistics prove that local enforcement agencies have seriously neglected their inspection and surveillance of tobacco sales practices since 1990.
Which one of the following does the author assume in reaching his conclusion?
选项:
A、A. Monitoring and enforcement of tobacco violations became more lax due to a change in the political climate in Washington, D.C.
B、B. The decrease in the number of citations was not due to a reduction in the number of tobacco sales actually made to minors.
C、C. Authorities focused more on enforcing the ban on liquor sales to minors than the ban on the sale of tobacco products to minors.
D、D. Local enforcement agencies suffered from a reduction in personnel during the period 1990-1995.
E、E. For several years prior to 1985, in excess of 1,500 citations per year were issued in connection with tobacco sales to minors.
