One pervasive theory explains the introduction of breakfast cereals in the early 1900s as a result of the growing number of automobiles, which led to a decline in horse ownership and a subsequent grain glut; by persuading people to eat what had previously been horse feed, market equilibrium was restored.

(A) by persuading people to eat what had previously been horse feed, market equilibrium was restored

(B) persuading people to eat what had previously been horse feed restored market equilibrium

(C) by persuading people to eat what had previously been horse feed, it restored market equilibrium

(D) the persuasion of people to eat what had previously been horse feed restored market equilibrium（B）

(E) market equilibrium was restored when people were persuaded to eat former horse feed 问一个问题，不是说分号前后应是两个独立的句子吗？

b后面不是句子呀？

请问这里E和B的差别仅仅是简洁性问题吗？

我还没明白E为什么错？

moodraie

former horse feed"

Dose "former" modify "horse" or "feed"?

bastencools

(B) persuading people to eat what had previously been horse feed restored

market equilibrium

(E) market equilibrium was restored when people were persuaded to eat former

horse feed

我觉得这个问题在于"what had previously been horse feed" 和 "former horse feed"

是不同的。前一个由于是代词what引导，只能特指这个题目里所说的那种原来是马饲料的

食品，而后面一个是泛指以前的马饲料。所以我觉得B是对的。如果把E改为"this former

horse feed"就对了。不知道大家怎么想？
