(A) The price of scrap iron on international markets rose significantly in 1987.

(C) There is virtually no difference in quality between steel produced from scrap iron and that produced from iron ore.

(E) Furnaces that process scrap iron can be built and operated in Country Y with substantially less foreign exchange than can furnaces that process iron ore.

165.

Choice E, the best answer, furnishes two pieces of information that together support the policy. First, furnaces that process scrap iron may be unable to process iron ore. Second, obtaining and operating furnaces that can process iron ore would require substantially more foreign exchange, thus possibly offsetting any advantage from processing domestic iron ore.

The possibility of increases in scrap iron’s price (choice A) speaks against the policy. The vulnerability of Country Y’s foreign-exchange reserves (choice B) emphasizes the need to conserve foreign exchange, but does not indicate which mode of steel production best accomplishes this. Choice C is neutral between the modes production. Choice D would support the policy only with assumptions about the reasons for the experts’ prediction.

if quality of steel produced from scrap iron > quality of steel produced from iron ore, support Country Y’s policy of buying scrap iron broad;

if quality of steel produced from iron ore > quality of steel produced from scrap iron ,weaken Country Y’s policy of buying scrap iron broad;

no difference in quality, neutral

若是两个质量相同的话，那么对scrap iron生产的steel加强也可，削弱也可

若是加强，就说：两者质量同，那位什么不用scrap iron生产，而用iron ore生产呢

若是削弱就说，两者质量同，那位什么不用iron ore生产，而用scrap iron生产呢

所以，是中立

我理解你的意思，但是因为这个选项本身的两面性，所以还是不能作为削弱

thanks a lot !!!!
