64. The imposition of quotas limiting imported steel will not help the big American steel mills. In fact, the quotaswill help "mini-mills" flourish in the United States. Those small domestic mills will take more business from thebig Americal 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 steels that are not produced by the big American steel mills.

  

请教此题的解题思路？谢谢。

I choose E. 既然小钢厂生产的东西和大钢厂不一样，当时也应当和外国的竞争．不是和大钢厂竞争．

还是不很明白，能否翻译题干的最后一句话，在讲讲思路？谢谢。

题干结论是进口钢铁限额的施加有益于小型钢铁厂，而不是大型的。因为小型厂从大型厂得到的生意比在没有进口限额下外国钢铁厂从大型厂获得的要多。E说的是小型厂生产的东西和大型生产的不一样。举个例子，大型厂生产A，如果小型厂和外国厂竞争，但是外国厂生产A，小型厂却生产B。 那么施加进口限额后，其实小型厂并没有得到什么好处。所以削弱原结论。

谢谢。我之所以问是因为不确定题干的最后一句话意思。题外话：题干最后一句话从语法的角度看好像不太平行啊，弄得我分不清比较的是什么。

可是如果小型厂和大型厂生产不一样的产品，比如小厂做粗加工，大厂精加工，小厂才能和海外厂竞争大厂的订单，如果一样不久是和大厂竞争了吗，那不就变成A,B,C,三者同时竞争了吗？

我有点不明白，请指教。谢谢

他们说的竞争不是小厂和海外厂之间竞争从大厂得到的订单，而是大厂小厂和海外厂一起竞争同一个美国国内市场。如果配额限制了海外厂参加，那么就要看配额对余下的两个竞争对手谁有利，是大厂得益还是小厂。如果大厂和小厂生产的产品不一样，那么小厂不会对大厂是否从配额政策得益构成影响，那么也就削弱了题目中说的配额实际对小厂有益，而不是对大厂有益的结论。因为从逻辑上讲，排除了这个原因。

谢谢：） 讲的真清楚！

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 America 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 steels that are not produced by the big American steel mills.

E is the best answer.

If, as choice E asserts, large and small mills produce different types of steels, increasing sales by small mills need not lead to decreasing sales by large one. Thus, choice E casts a serious doubt on the claim and is the best answer.

Choice A does not present enough information about the relative quality of steel from foreign and domestic mills to cast any doubt on the claim. Similarly, choice B does not provide enough information about small American mills, nor does choice C provide enough information about the likely consequences of quotas imposed by foreign countries to cast doubt on the claim. Choice D tends to support the claim, since better steel should sell better than poorer steel.

不明白D为什么是支持？Domestic “mini-mills” consistently produce better grades of steel than do the big American mills.－－》所以有无进口限制，小厂都比大厂销量好

You are wrong, because the conclusion is "Those small domestic mills will take more business from thebig Americal steel mills than would have been taken by the foreign steel mills in the absence of quotas", not "进口钢铁限额的施加有益于小型钢铁厂",

"那么施加进口限额后，其实小型厂并没有得到什么好处" is wrong, because "In fact, the quotaswill help "mini-mills" flourish in the United States". it is the evidence, not the conclusion.
