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.(A)

7. Firms adopting “profit-related-pay” (PRP) contracts pay wages at levels that vary with the firm’s profits. In the metalworking industry last year, firms with PRP contracts in place showed productivity per worker on average 13 percent higher than that of their competitors who used more traditional contracts.
If, on the basis of the evidence above, it is argued that PRP contracts increase worker productivity, which of the following, if true, would most seriously weaken that argument?
(A) Results similar to those cited for the metalworking industry have been found in other industries where PRP contracts are used.
(B) Under PRP contracts costs other than labor costs, such as plant, machinery, and energy, make up an increased proportion of the total cost of each unit of output.
