求助：prep 172(链接里没有。。。)

172. The hognose snake puts on an impressive bluff, hissing and rearing back, broadens the flesh behind its head the way a cobra does, feigning repeated strikes, but, having no dangerous fangs and no venom, eventually, if its pursuer is not cowed（威吓）by the performance, will fall over and play dead.

A. broadens the flesh behind its head the way a cobra does, feigning repeated strikes, but, having no dangerous fangs and no venom,

B. broadens the flesh behind its head the way a cobra does and feigns repeated strikes, but with no dangerous fangs and no venom,

C. broadening the flesh behind its head the way a cobra does and feigning repeated strikes, but it has no dangerous fangs and no venom, and

D. broadening the flesh behind its head the way a cobra does and feigns repeated strikes, but with no dangerous fangs and no venom, and

E. broadening the flesh behind its head the way a cobra does, feigning repeated strikes, but with no dangerous fangs and no venom, and

A: 两个动词之间应该有连词

B: 同上, 两个动词之间应该有连词,but后面又是一个单独的句子了

C: correct

D: broadening 和 feigns不平行；but with no 不如用句子表达好

E: broadening 和feigning之间必须有连词

注意：

1、but with no这种介词结构在GMAT里，都倾向用完整的句子方式进行表达

2、目的状语并列必须用连词不能用逗号，以前考过，所以E错

这句话是什么意思啊？哪几个成分之间平行？晕了。。。有没有NN帮忙翻译以下。。
