OG12 43 D和E选项的区别

nonozx

Laos has a land area about the same as Great Britain but only four million in population, where many are members of hill tribes ensconced  in the virtually inaccessible mountain valleys of the north.

D.comparable to the size of Great Britain, but only four million in population, and many
E.comparable to that of Great Britain but a population of only four million people, many of whom


D选项没有语法错误，句意也通顺。OG解释说D中and的引入造成了在很多强调老挝人都住在难以接近的地方因而错了，E是正确的。
我能理解这里的意思，但是我的问题是：在考GMAT SC时，我们怎么判断E就是作者想表达的意思而D不是？

Actually, D) compares "land area" with "size of Great Britain"; therefore it is incorrect. The elements being compared must be logically and structurally paralleled.

同意楼上的解释，d选项比较的都不对称。这道题出做时我也错了，没仔细看题。不过比较是我的弱项。呵呵

理解了。谢谢。不过OG上没提到这个，可能是认为前几个选项中已经解释过该考点了。

我的理解是：E中的结构更利于句子意思的理解，Laos has a land area *****, and a population of ****,这样的结构更利于理解，看来GMAC中句子逻辑和结构是第一位，太过于抠语法细节可能不大利于做题

同意LZ 的观点， 从句的 laos has 和主句一样省略， 所以从句的主要强调是有400 万人

口（主干重心），  然后在补充提到人口还有许多在山区（次要修饰作用）。。
