Country Y uses its scarce foreign-exchange reserves to buy scrap iron for recycling into steel;Although the steel thus produced earns more foreign exchange than it costs, that policy is foolish;Country Y's own territory has vast deposits of iron ore, which can be mined with minimal expenditure of foreign exchange.
Which of the following, if true, provides the strongest support for Country Y's policy of buying scrap iron abroad?

Which of the following,if true,provides the strongest support for Country Y's policy of buying scrap iron abroad?
(A)The price of scrap iron on international markets rose significantly in 1987.
(B)Country Y's foreign-exchange reserves dropped significantly in 1987. (C)There is virtually no difference in quality between steel produced from scrap iron and that produced from iron ore. (D)Scrap iron is now used in the production of roughly half the steel used in the world today, and experts predict that scrap iron will be used even more extensively in the future. (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.
文中说that policy is foolish是指买scrap iron做钢对吧? 还有C错在哪里啦, VR上的答案解释我看不太懂,不是说两个方式的质量一样吗, 怎么会preempt inferior有看懂的NN请帮忙解答一下吧, 拜托啦!!!!~
This statement helps to preempt a possible objection to the present policy---namely that steel from scrap iron is inferior to steel from iron ore. But it equally helps to preempt a possible objection to changing the present policy---namely that steel from iron ore is inferior to steel from scap iron. It therefore provides no evidence that would weigh distinctly in favor of maintaining the present policy, as opposed to changing it.
(C) reconciles the attitude that the passage tried to establish "that policy is foolish". Given information between scrap iron and iron ore does not clearly differ to one another. Thus, this alternative weakens the attitude quotated above.
