12. If new working practices raise a firm’s productivity, will the firm respond by paying its workers more? Not in a competitive market. In such a market the firm, to gain a competitive edge, will reduce prices. The workers’ real wages, as measured by those wages’ purchasing power, will still rise because of lower prices.

In a competitive market which of the following, if true, ensures that the workers of a firm that achieved productivity gains will derive from these gains the benefit of higher real wages?

(A) The workers’ firm continues to achieve productivity gains.

(B) Other firms do not achieve comparable productivity gains.

(C) The workers buy products made by the firm that employs them.

(D) The workers prefer the new working practices over the old.

(E) The firm pays its workers at or above the industry’s average.

答案是C，这道题我问题一直没有看明白，看了选项更迷糊了，恳请大家帮忙解释一下，THANKS IN ADVANCE

主要是说，工人的劳动生产率提高了，由于竞争，则该公司的产品通常会降价；所以，结论说，即使工人工资没有增加，工人的实际收入（相对于商品），也将因为价格下降而增加。

题目没有说其他的劳动生产率是否提高，所以，只有购买自己公司的产品，才能确保商品的结论成立。

注意ensure，我想可以理解为必要条件吧。

另外，做逻辑体一定要注意推理过程和结论的具体性和特殊性。

sorry,

"才能确保商品的结论成立"

中的"商品"，应为"上面"。

howardwang,偶今天问了四个题目，两个语法，两个逻辑，你已经热心回答了三个了，真的十分感谢啊!

P.S.这道题偶题目原来没看明白，现在看了你的解释，明白了，看来偶的阅读能力太差了，汗颜。。。。。。
