OG10th, No. 11,

Based on accounts of various ancient writers, scholars have painted a sketchy picture of the activities of an
all-female cult that, perhaps as early as the sixth century B.C., worshipped a goddess known in Latin as
Bona Dea, "the good goddess."

该选项错误的原因是：In choice A, the introductory clause beginning Based on modifies scholars, the noun that immediately follows it: in other words, A says that scholars were based on the accounts of various ancient writers.

而我觉得这边的based on 是修饰paint这个动作的。

有一题大全题目（大全131）就是：

No state law forbids an employer from rejecting a job applicant or to dismiss an employee based on the results of a lie detector test.

这里的based on 就是修饰动作的吧？

实际上我们在平时用的时候就经常用“based on blablabla, somebody arrived at a conclusion ..."

疑惑...

NN,请帮忙解答，我和楼主有同样的疑惑！！
