[求助]OG-165还没解决的疑惑

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neutraldoes not indicate which mode of steel production best accomplishes this这样的OG解释

不知你的問題在哪

但在我看來A 只講scrap iron,不完整,不選

B,離題太多,不選;C, no difference 不選

D,沒啥相關,不選

这类题目我把它分为选择类,即凡是涉及两类比较(A,B),不是支持削弱就是ASSUME,如OG74,129,87,100,31,64,93,96,146,,157,158,163,168,等等可以归类的

如果支持A,就选A的优点

如果削弱A,就选A的缺点

如果ASSUME,那么A, B没有区别

当然可能说的太笼统了,不过就按照本题来说可是这样理解

A;scrap iron(进口的,要外汇买)  .B: iron ore(本国自己的,不涉及外汇),题目要求支持外汇买scrap iron这个政策,尽管外汇贮备较少

答案A中scrap iron价格上升,会用更多的外汇,削弱

答案B中,外汇贮备下降,但是未涉及A,B的比较

答案C中,AB没有区别,不选

答案D中,如果正如专家预测的,对scrap iron的需求增大,那么可以the steel thus produced WILL  earns more foreign ,支持该政策,但是如果专家预测失灵呢?

答案E涉及AB的比较,至少说明A优于B,所以正确
