讲的很清楚，完美~但是allow sb to do rather than do（be confined）这样是不是前后就不平行了？ ...

这里省略了to，GMAT里面经常省略to。。。  allow sb to do rather than （to）do。。

然后这道题是这样的
1、instead of +ving/n. 但是在gmat里面只喜欢用n.，如果用动词，那么gmat prefer用rather than，rather than后面动词原形或者ving都可以。 哪怕主句的动词是过去式。
例子：
Instead of buying stocks and bonds, which is the more conventional approach for someone new to
financial planning, real estate has become increasingly attractive to young people looking for a first investment.

Instead of buying stocks and bonds, which is the more conventional approach for someone new to financial planning, real estate has become increasingly attractive to young people as a first investment.
Instead of buying stocks and bonds, which is the more conventional approach for those new to
financial planning, young people have shown an increasing attraction to real estate as a first
investment.
Rather than buying stocks and bonds, which is the more conventional approach for someone new to financial planning, real estate has become increasingly attractive to young people looking for a first investment.
Rather than buy stocks and bonds, which are the more conventional instruments for those new to financial planning, young people have turned increasingly to real estate as a first investment.* key
Instead of stocks and bonds, which are the more conventional approach for those new to financial planning, young people have shown an increasing attraction to real estate as a first investment.

Rather than accept the conventional wisdom that the earth was flat, Christopher Columbus was sent by the king and queen of Spain to see if he could reach India by traveling west.

Rather than accept the conventional wisdom that the earth was flat, Christopher Columbus

Rather than accepting the conventional wisdom that the earth was flat, Christopher Columbus

Instead of accepting the conventional wisdom that the earth was flat, Christopher Columbus
sailed west to see whether he could reach India, having been sent by the king and queen of
Spain.  
rather than更优。
Rather than accept the conventional wisdom that the earth was flat, Christopher Columbus
sailed west to see whether he could reach India, having been sent by the king and queen of
Spain.（key）

Instead of accepting the conventional wisdom that the earth was flat, Christopher Columbus

2、楼主说的 to allow和to confine them平行文我也想过。我觉得这样平行当然没有问题。但是问题是，to allow them 后面还有一个to 的不定式，to go home，这样的话，和这个后面的不定式平行会有歧义，变成allow them to confine them。允许他们自己限制自己。而E是没有这个歧义的 allow them to be confined 很清楚是陪审团的人被限制。只是很tricky地省略了to。
to不定式在gmat中经常省略这一点要记住。

Unlike the original National Museum of Science and Technology in Italy, where the models are encased in glass or operated only by staff members, the Virtual Leonardo Project, an online version of the museum, encourages visitors to "touch"(v.) eachexhibit, which thereby activates the animated functions of the piece.

(A) exhibit, which thereby activates是touch这个动作activate而不是exhit自己能activate
(B) exhibit, in turn an activation of  什么activation? 前面一句是encourages visitors to "touch" each exhibit，这个不是想要指代的activation吧。
(C) exhibit, and it will activate 是touch这个动作activate而不是exhit自己能activate
(D) exhibit and thereby activate （key）省略了 (to) activate
(E) exhibit which, as a result, activates是touch这个动作activate而不是exhit自己能activate

3、看到不定式就要想到有没有歧义

The United Parcel Service plans to convert its more than 2,000 gasoline-powered trucks in the Los Angeles area to run on cleaner-burning natural gas.

• (A) to convert its more than 2,000 gasoline-powered trucks in the Los Angeles area to （key）
• (B) to convert its more than 2,000 trucks in the Los Angeles area that are powered by gasoline to【 to前面有个that，会有修饰歧义，变成 to后面的不定式也是修饰这2000个trucks】
• (C) on converting its more than 2,000 gasoline-powered trucks in the Los Angeles area that will
• (D) for its more than 2,000 gasoline-powered trucks in the Los Angeles area to convert to
• (E) that its more than 2,000 trucks in the Los Angeles area that are powered by gasoline will convert to
