Country Y uses its scarce foreign-exchange reserves to steel thus produced earns more foreign exchange than has vast deposits of iron ore，which can be mined with buy scrap iron for recycling into steel．Although the it costs，that policy is foolish．Country Y's own territory 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?

(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．

答案是E。我一开始选的是C，我觉得如果用两种原料，铁的质量一样的情况下，Y可以把自己的iron ore开采出来卖个高价钱，而从别人那里收购低价的scrap iron来炼铁，这样还是划算的。
