Key is E

why not choose A?

TGWD1-3

1 这是GMAT语法的一个原则，主语要靠近主句。A中叙述过于复杂，主语离最后的句子太远了。E很简练。

2。独立主格，名次+分词，修饰现行词Shades.  The other choices will change the original meaning of sentence.

为了避免阳光直晒，M人居住在一个四面通透，平顶的以荫凉著名的屋子里，每个屋顶都是由横梁和茅草做成，由围成长方形的柱子们支撑。

谢谢姐姐的翻译

1-2
for his attempt...
for感觉很怪啊，而且同时又用了therefore...整个读起来显然没有E顺畅。

For protection from the summer sun, the Mojave lived in open-sided, flat-topped dwellings known as shades, each a roof of poles and arrowweed supported by posts set in a rectangle.

这句话挺迷惑人的，前面是dwellings,后面我本来选roofs, 现在想想：

1。GMAC还是觉得独立主格比with加定语从句要简洁；

2。后面是a rectangle,一个长方形的顶当然只有一个，虽然后面来个迷惑的posts.

1-3中的each a roof是什么用法呢？each+a+n.?

我认为不选A还有个重要的原因是therefore副词不能代替连词，两个独立句之间没有连词。

想请教一下GWD1-2为什么不选B呢？谢谢

(B) When Charles Lindbergh was attempting his solo transatlantic flight, being very reluctant to have any extra weight on his plane, he
B里面的bing very reluctat 的结构不对，而且容易产生歧义吧？
