Q8:

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.

Q11 第一个statement说的是placed by subscribers under age thirty-five,第二个说的是placed by people under age thirty-five,就是说很多下了订单的人没订杂志。比如总共有100个订单，这里面30个人是35岁以下而且订了杂志的，第二个statement说大多数人都是35岁以下，那假设是70个人吧，期中有40个人就是没订杂志的，但是下了订单的。
