咨询OG10th 158,160,178三道语法题

请各问大虾们帮忙解释下这三道让小妹实在困惑的语法题，第一次问问题，有点腼腆，请大家多多支持:

158.With only 5 percent of the world's populations, United States citizens consume 28 percent of its nonrewable resources, drive more than one-third of its automobiles, and use 21 times more water per capita than Europeans do.

A.With

B.As

C.Being

D.Despite having

E.Although accounting for

(E)

160.While some propose to combat widespread illegal copying of computer programs by attempting to change people's attitudes toward pirating, others by suggesting reducing software prices to decrease the incentive for pirating, and still others by calling for the prosecution of those who copy software illegally.

A.by suggesting reducing software prices to decrease the incentive for pirating, and still others by calling

B.by suggesting the reduction of software prices to decrease the incentive for pirating, and still others call

C.suggest the reduction of software prices for decreasing the incentive for pirating, and still others call

D.suggest the reduction of software prices to decrease the incentive for pirating, and still others by calling

E.suggest the reducting software prices to decrease the incentive for pirating, and still others are calling

(E)

这道题考的是平行结构，书上给的答案是说：some propose ...others suggest...and still others are calling

一般现在时和现在进行时可以算是一种平行结构吗？

178.In the last few years, the number of convicted criminals given community service sentences, which allow the criminals to remain unconfined while they perform specific jobs benefiting the public, have risen dramatically.

D.sentences which allow them to remain unconfined in their performing of specific jobs beneficial to the public has

E.sentences allowing them to remain unconfined while performing specific jobs that  benefit the public has

(E)

在D中答案说“in their performing of specific job ”WORD AND IMPRECISE？让我很CONFUSED

有沒有哪位大師給我一個更強烈的答案ne?

160 IMO

首先后面得跟句子，要不不完整，AB排除

平行结构排除D，

C E 不定式好像优于现在分词来修饰reduce

还有 suggest doing sth 表建议  suggest +N. 是不是就改变原来的意思了?

E 最优。

现在GMAT语法狂错中,受不了了
