问题 单项选择题

采用“利润相关报酬”(PRP)合同的企业支付的工资水平随企业利润而变动。去年,金属工艺行业中适当采用PRP的企业的每个工人的生产率,比那些仍然使用较传统合同的竞争者平均高13个百分点。
根据以上的证据,如果有意见认为PRP合同提高了工人的劳动生产率,下面哪个如果正确,最严重地削弱了这种意见

A.与以上引用的金属工艺行业相似的结论可以在使用PRP合同的其他行业中被发现。
B.在PRP合同之下,除了劳动力成本以外的那些成本——例如建筑、机器和能源成本——在单位产量的总成本中所占比重上升了。
C.因为引入PRP合同极大地改变了单个工人同企业之间的关系,对引入PRP合同进行谈判是复杂和费时的。
D.金属工业行业中很多企业在过去的5年中已经将其生产设备现代化了,同时这些企业中大多数引入了PRP合同。
E.在金属工艺行业中适当采用PRP合同的企业中,平均的实际工资比那些工人拥有更多传统合同的企业高出15个百分点。

答案

参考答案:D

解析:题干将“工人的劳动生产率的提高”归因为“PRP合同”,选项提出生产设备的现代化是原因,属于他因削弱。
