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."

(A) Based on accounts of various ancient writers

(B) Basing it on various ancient writers' accounts

(C) With accounts of various ancient writers used for a basis

(D) By the accounts of various ancient writers they used

E）Using accounts of various ancient writer

From ETS:Choice B is awkward and impre­cise in that the referent for the pronoun it is not immediately clear.

我的问题是，是不是ETS 认为代词指代的只能是前文出现的，而不能指代后文出现的，比如picture...

it 应该可以指代后面的，但是在这里若it指代picture的化，逻辑意思上说不通，不能既“base picture",又“paint picture".

请NN门指点!
