In the year following an eight-cent increase in the federal tax on a pack of cigarettes, sales of cigarettes fell ten percent. In contrast, in the year prior to the tax increase, sales had fallen one percent. The volume of cigarette sales is therefore strongly related to the after-tax price of a pack of cigarettes.
Which of the following, if true, would most strengthen the argument above?
A. During the second year after the tax increase, cigarette sales increased by a significant amount.
B. The information available to consumers on the health risks of smoking remained largely unchanged in the period before and after the tax increase.
C. Most consumers were unaware that the tax on cigarettes was going to increase.
D. During the year following the cigarette tax increase, many consumers had less income, in inflation-adjusted dollars, than they had had in the previous year.
E. During the year after the tax increase, there was a greater variety of cigarettes on the market than there had been during the previous year.

The argument above requires which of following assumptions?
A During the year following the tax increase, the pretax price of a pack of cigarettes did not increase by as much as it had during the year prior to the tax increase.
B The one percent fall in cigarette sales in the year prior to tax increase was due to a smaller tax increase.
C The pretax price of a pack of cigarettes gradually decreased throughout the year before and the year after the tax increase.
D For the year following the tax increase, the pretax price of a pack of cigarettes was not eight or more cents lower than it had been the previous year.
E As the after-tax price of a pack of cigarettes rises, the pretax price also rises.
2、假设题
Personnel officer: The exorbitant cost of our health-insurance benefits reflects the high dollar amount of medical expenses incurred by our employees. Employees who are out of shape, as a group, have higher doctor bills and longer hospital stays than do their colleagues who are fit. Therefore, since we must reduce our health-insurance costs, we should offer a rigorous fitness program of jogging and weight lifting to all employees, and require employees who are out of shape to participate.
The conclusion reached by the personnel officer depends on which of the following assumptions?
A. A person who is fit would receive a routine physical checkup by a doctor less regularly than would a person who is out of shape.
B. The medical expenses incurred by employees who are required to participate in the fitness program would be less than those incurred by employees who are not required to participate.
C. The strenuous activities required of out-of-shape employees by the program would not by themselves generate medical expenses greater than any reduction achieved by the program.
D. The fitness program would serve more employees who are out of shape than it would employees who are fit.
E. The employees who participate in the fitness program would be away from work because of illness less than would the employees who do not participate.

Which of the following, if true, provides the most support for the personnel officer's proposal?
A. The medical expenses incurred by fit people who participate in a program of jogging and weight lifting are less than those incurred by fit people who do not participate in such a program.
B. More otherwise fit people are injured by participating in rigorous jogging and weight-lifting programs than are injured by participating in moderate jogging and weight-lifting programs.
C. The likelihood of incurring medical expenses is slightly greater for people who participate in fitness programs offered by their employers than it is for people who participate in programs offered commercially.
D. Moderate fitness programs increase the average person's fitness to the same extent that rigorous fitness programs do.
E. More health problems and injuries are the result of mandatory participation in a fitness program than are the result of voluntary participation.
