a.
b.fell substantially, while the number of Blacks attending college is more than double what it was at that time
c.has fallen substantially, while the number of Blacks attending college has more than doubled
d.has fallen substantially over the past decade,while the number of Blacks attending college is more than twice what it was at that time
e.has fallen substantially over the past decade, while the number of Blacks who are attending college are more than double what they were
答案选E，可是E中while后面the number是主语不是应该跟is？但后面用了are，while这句不是主谓不一致了吗？还有C为什么错呢？我觉得A，D,E里面in the last ten years和over the past decades重复了。请各位大牛指教一下，不胜感激！作者: francoiswang 时间: 2010-1-8 18:38
