标题: [求助]OG-145

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A


想了半天,看了半天的解释也不明白为什么是A?


这个occupancy rate和admission rate究竟有什么关系?为什么明明是rate的问题怎么会扯上time的问题?


真是百思不得其解!!

adminission rate 是指一定的床位中,有多少adminssions, occupancy rate 是指一定的时间内有多少床位住着人. 如果administion rate一定, occupancy rate 大就说明床位住人的时间长.现在administion rate减少,而occupancy rate 增加,当然住人的时间就更长.不知道我表达清楚了没有?

也许应该这样说,occupancy rate 是指床位住人和不住人的时间比.
