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.

答案给出的是A。我选的是C。

请NN指教一下，为什么C不对？

对于A的话，有可能occupancy rates rise是因为occupancy的人多了，如A离开后B又occupied，并一定是average length of time stayed increased.

请帮忙解答下，谢谢哦！

平均每张床的新进人数减少了， 但是平均每张床的占有人数却增加了， 从而推出，平均每张床的离开人数减少， 那么平均每张床老顾客呆的时间就多了

C 选项 干脆就总结了一个规律， 显然夸大了原文支持范围。

谢谢jbyupei的回答。

原来admission rate我理解错了，我理解成occupancy rate是暂住的，而admission是成为会员的，呵呵。
