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.

论述：
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．
大的政府预算赤字通常不会引起大的交易(商业）赤字。如果会的话，那么那些最大政府预算赤字的国家也将会面临最大的贸易赤字。事实上，赤字是会被调整的，这样一来，不同的国家才能各自有个相对可靠的比较。因此，两者没有非常大的相互关系。
问题：
If the statements above are all true， which of the following can properly be inferred on the basis of them？
如果以上论述属实，那么下列基于论述的推测，那个是正确的（合适的）？
选项：
A countries with large national budget deficits tend to restrict foreign trade
那些巨额政府预算赤字的国家将限制国外贸易。
（文章没讲赤字和foreign trade的关系，所以A排除）
B Reliable comparisons of the deficit figures of one country with those of another are impossible．
将一个国家的赤字数据和同样状况的另一个国家进行可靠性比较，这是不可能的。
（论述最后一句说了两者的比较是没有很大的关系，并没有讲可不可能的问题）
C reducing a country’s national budget deficit will not necessarily result in a lowering of any trade deficit that country may have．
减少一个国家的政府预算赤字并不会必然的引起这个国家的任何贸易赤字的降低。
（此论述符合题意，因此选C）
D when countries are ordered from largest to smallest in terms of population，the smallest countries generally have the smallest budget and trade deficits．
如果国家按照人口大小从大到小排序，那么最小人口国自然是最小政府预算和贸易赤字国
（文中根本没提到关于人口的问题，也没提人口和预算赤字以及贸易赤字的关系，因此可以排除）
E Countries with the largest trade deficits never have similarly large national budget deficits
最大贸易赤字国从不有相近的政府预算赤字状况。
（文中只说两者没有很深的联系，即政府预算赤字与贸易赤字无关，并不说贸易赤字和政府预算赤字没有类似的状况，因此排除）
ps：翻译可能不是很到位（专业），但应该是选C的，希望有帮到你哦！
