Q11. p2-cr 39. (32799-!-item-!-188;#058&007548)a

The imposition of quotas limiting imported steel will not help the big American steel mills. In fact, the quotas will help "mini-mills" flourish in the United States. Those small domestic mills will take more business from the big American steel mills than would have been taken by the foreign steel mills in the absence of quotas.

Which of the following, if true, would cast the most serious doubt on the claim made in the last sentence above?

(A) Quality rather than price is a major factor in determining the type of steel to be used for a particular application.
(B) Foreign steel mills have long produced grades of steel comparable in quality to the steel produced by the big American mills.
(C) American quotas on imported goods have often induced other countries to impose similar quotas on American goods.
(D) Domestic "mini-mills" consistently produce better grades of steel than do the big American mills.
(E) Domestic "mini-mills" produce low-volume, specialized types of steel that are not produced by the big American steel mills.
正确答案是E。
我的选择是A。
我的理解是：题目中宣传小工厂可以抢走大工厂的活儿，前提是抢得走，A项称“质量重要”，也就使小工厂抢大工厂活儿的可能性消弱了。
求解！

A没说大工厂的质量比小工厂好啊

E项是说小厂生产的产品是大厂所不能生产的'是独特的'所以不算是抢生意,weaken

这题是这样的..首先明白论据和结论..
论据:小厂拿走了大厂的生意(这些生意原来是国外厂商把握的)
结论:小厂利润上升了

A选项的意思是说质量比价格更重要..这首先就是个无关比较的错误类型..其次就算A成立..原文中没有信息告诉我们小厂的质量就不好了.见我上面写得论据和结论.
D选项和A错法一样..原文没有提到质量.从而无法削弱结论..
E选项的意思是小厂生产的钢材类型和大厂不同..这个就直接削弱了论据和结论之间的关系..因为可以推出拿不走大厂的生意..从而反对了结论小厂利润上升了..
总结一下..削弱题就是说论据成立了但是结论不一定成立..
原文论据小厂可以拿走之前外国厂商在大厂的生意成立之后..由于E的削弱..结论小厂利润上升了也不一定成立...
E为正解..

恩，我在推理的时候参入了自己的理解，主观地把小厂理解为“质量差”，所以选了A。谢谢大家的帮助
