看了以前的帖子，发现这个问题一直没有一个很好的解释，25题based on不能修饰scholars我理解，按照这个道理28题里based on就不能修饰the Mochica，有人说修饰society，但是这里有个帖子http://forum.chasedream.com/GMAT_SC/thread-433525-1-1.html里面说了

If a participial phrase comes at the end of a sentence, a comma usually precedes the phrase if it modifies an earlier word in the sentence but not if the phrase directly follows the word it modifies.

The local residents often saw Ken wandering through the streets.
(The phrase modifies Ken, not residents.)
Tom nervously watched the woman, alarmed by her silence.
(The phrase modifies Tom, not woman.)

实在想不通为什么了。。。有哪位NN能解答吗？

同问。
如果based on是修饰society的话，就不需要comma分开；如果是修饰主句主语的话，就不应该是被动结构。牛牛快来~~

其實based on放在句子首你可以把句子的主語放到他前面去例如scholars based on accounts of various ancient writers, 這樣子句子的意思就不對了 scholars不能based on 他是動作的發出者應該用主動，

第二題考點是平行

很有争议的问题，我也来说说我的观点如有不足还望指出。

There is no ambiguity in the sentence that the phrase "wandering through the street" modifies "Ken". Remember the idiom "See somebody doing something?"

The second question involves the use of modifier. In general, the noun modifier (过去分词) must precede or follow immediately after the noun it modifies. For example,
“Shocked by the bad news, Emily ate two hotdogs.” Here, “shocked” clearly modifies “Emily”
“Emily ate two hotdogs, shocked by the bad news” Here, “shocked” modifies “hotdogs”

This rule is generally followed by GMAC. Let’s also look at one example from OG.
Verbal Review 1st Ed. 91 “In theory, international civil servants at the UN are prohibited from continuing to draw salaries from their own governments; in practice, however, some governments merely substitute living allowances for their employee’s paychecks, assigned by them to the United Nations.”
OG explains “assigned by them incorrectly and illogically modifiers paychecks”

Now let’s look at the second sentence:
"Tom nervously watched the woman, alarmed by her silence.
(The phrase modifies Tom, not woman.) "

By the same token, “alarmed by her silence” modifies “the woman”, right?However, here the issue gets complicated. Because by default we know that Tom is a guy, therefore, “her” CANNOT refer back to Tom. Otherwise we will have a nonsensical sentence that reads "Tom nervously watched the woman, alarmed by her [Tom’s] silence."

Let’s change the sentence a little bit, and now it reads:
"Sarah nervously watched the woman, alarmed by her silence."

Now the noun modifier “alarmed by her silence” will unambiguously modifiers “the woman.” The sentence read “Sarah nervously watched the woman, alarmed by her [Sarah’s] silencFor this reason, I’d argue that the second sentence is an exception and that tt is not really a good example. Here is a better way to write the sentence: "Alarmed by her silence, Tom nervously watched the woman." “Alarmed by her” clearly modifies “Tom.”

So here is the catch: In general, the noun modifier (过去分词) must precede or follow immediately after the noun it modifies, as the GMAC generally follows this rule.
