pp3review上的第25和26题，为何不能剪贴、复制呢，痛苦：）
25) Between 1975 and 1985,nursing-home occupancy rates averaged 87 percent of capacity,while admission rates remained constant,at an average of 95 percent and admissions per 1000 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 1000 beds per year.
A.The average length of time nursing-home residents stayed in nursing homes increased between 1985 and 1988.
D.Nursing homes built prior to 1985 generally had fewer beds than did nursing homes built between 1985 and 1989.
我知道a是对的，但d为什么不对呢？因为床位少，所以虽然申请人减少了，但占有率还是增加了。是不是因为d不够严密？

25). D. is not as direct as A. More beds doesn't necessarily lead to higher PERCENTAGE of occupancy.
