题目较长,先谢谢了
165. 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 following, if true , provide the strongest support for country's policy of buying scrap iron aboard??
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 opereated in country Y with substantially less foreign exchange than can furnaces that process iron ore.
OG解释(关于BC)
1. the vulnerability of country Y's foreign exchange reserves (B) emphaseze the need to conserve foreign exchange(这句话没问题,我理解), but does not indicate which mode of steel production best accomplishes this.(个人觉得假如把B和题目中的其他条件结合看,应该是说iron ore 会好一些,因为它花费的foreign exchange 会比scrap iron 少, 所以不是does not indicate which mode of steel production best accomplish this)
2. choice c is neutral between the modes of production(我觉得同样把C结合题目中的条件看的话应该是说iron ore 会好一点,因为质量一样,而iron ore价格又便宜一点)
3. 只有在已知正确答案C的情况下,看BC才会得出neutral或does not indicate which mode of steel production best accomplishes this这样的OG解释
