请教大全17-6

Between 1975 and 1985, nursing-home occupancy rates averaged 87 percent of capacity, while admission rates remained constant, at an average of 95 admissions per 1,000 beds per year. Between 1985 and 1988, however, occupancy rates rose to an average of 92 percent of capacity, while admission rates declined to 81 per 1,000 beds per year.
If the statements above  are true, which of the following conclusions can be most properly drawn?
(A) The average length of time nursing-home residents stayed in nursing homes increased between 1985 and 1988.
(B) The proportion of older people living in nursing homes was greater in 1988 than in 1975.
(C) Nursing home admission rates tend to decline whenever occupancy rates rise.
(D) Nursing homes built prior to 1985 generally had fewer beds than did nursing homes built between 1985 and 1988.
(E) The more beds a nursing home has, the higher its occupancy rate is likely to be.
75-85年间,护士之家的居住率为87%,准入率为95%.85-88年间,居住率为92%,但准入率为81%。疑点在,85-88年的准入率降低后,居住率反而升高。
explain:85-88年间的病人住院时间长--正选是A无可非议,但是,在下的疑问是:问什么C不对?
盼指教~~:-)

个人觉得,c提供的结论是:当occupancy rate 上升时,admittion rate下降。但是原文只是这个结论的一个例子,并不能从原文推出这个结论。

注意推导题必须仅依据原文事实。不能“发明”原文没说的/推不出的东西。

c原文没有提到。
