又來求助了 OG12-116

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.
(C)  Because introducing PRP contracts greatly changes individual workers' relationships to the firm, negotiating the introduction of PRP contracts is complex and time-consuming.
(D)    Many firms in the metalworking industry have modernized production equipment in the last five years, and most of these introduced PRP contracts at the same time. （correct answer）
(E)    In firms in the metalworking industry where PRP contracts are in place, the average take-home pay is 15 percent higher than it is in those firms where workers have more traditional contracts.

看了之前的求助帖 還是有一個小不明白
關於E take-home pay到底是指什麽？做題的時候我理解為“空手套白狼”的漲工資。工資的增加要比productivity的增加還要多。這可以weaken the argument that PRP contracts increase worker productivity嗎？這個彎一直轉不太過來 希望有人可以幫幫忙 謝謝！！

我觉得是个无关选项啊，原文说的是PRP和产量的关系，E选项说的是税后工资，这个税后工资是是因为产量增长所以增长的，但是是不是跟PRP有关，不知道。
