GMAT逻辑题,不懂啊,求教.
Large national budget deficits do not cause large trade deficits．If they did,countries with the largest budget deficits would also have the largest trade deficits．In fact,when deficit figures are adjusted so that different countries are reliably comparable to each other,there is no such correlation．
If the statements above are all true,which of the following can properly be inferred on the basis of them?
（A） Countries with large national budget deficits tend to restrict foreign trade．
（B） Reliable comparisons of the deficit figures of one country with those of another are impossible．
（C） Reducing a country’s national budget deficit will not necessarily result in a lowering of any trade deficit that country may have．
（D） When countries are ordered from largest to smallest in terms of population,the smallest countries generally have the smallest budget and trade deficits．
（E） Countries with the largest trade deficits never have similarly large national budget deficits．

C
两个要点：第一,文中的关键是,budget deficit和trade deficit没有必然联系,所以凡是选项中提到二者有联系的,都是错误选项；第二,在infer题中,若选项中存在原文中没有提到的要素,也错.
A：没有提到restrict
B：没有提到comparison
C：正确,关键词“not necessarily”
D：没有提到population
E：原文说的是“没有关系”,然而“never have...”（“必然不导致”的关系）也是一种关系,所以错.
