145. 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.

我也选的c,请nn帮忙解释一下，谢谢！

I think the answer is A, rite?

There is a paradox in this problem, the higher admission rate, the lower occupancy, while the lower adimssion rate, the higher occupancy.Only A can explain why this could happen. Because people stay in nursing house for a longer time than ever, that's why lower admission rate can still cause the increasing number of people in the nursing house gradually.

C的意思是说任何时候occupancy rate升高, admission rate就升. OG解释说题干里并没有说明1975-1985年发生的情况是正常的还是不正常的, 所以不能作出C这样的推理.

C在说occupancy与admission之间的因果关系，但原文只是两种现象的同时发生，没有因果关系。

可我认为这两者的确存在此增彼长的关系啊

不选是因为whenever太绝对，这样的答案一般是错的？

问题问的是从现象可以得出哪项推论是正确的。现象：1985－1988，occupancy rate rose while admission rate fell. 结论：c选项说admission rate decline whenever occupancy rate rose. 从一个现象推出一个很绝对的规律，不对，是hasty generalization.
