According to Interstudy, a nonprofit organization that studies health maintenance organizations (HMO’s), they estimate that, in comparison to last year, when only 36 percent of the nation’s 607 HMO’s was profitable, this year 73 percent will be.
(A) they estimate that, in comparison to last year, when only 36 percent of the nation’s 607 HMO’s was profitable, this year 73 percent will be
(B) compared to only 36 percent of the nation’s 607 HMO’s being profitable last year, they estimate 73 percent would be this year
(C) only 36 percent of the nation’s 607 HMO’s were profitable last year; it estimates that this year 73 percent will be
(D) it estimates 73 percent of the nation’s 607 HMO’s would be profitable this year; last year that was only 36 percent
(E) only 36 percent of the nation’s 607 HMO’s last year were profitable, whereas they estimate it this year to be 73 percent

大家能不能简单的说说这里的C 选项  WILL BE 的BE 能不能胜

另外，为什么  only 36 percent of the nation’s 607 HMO’s were profitable last year   这里用WERE 那？？？

前面不是一个数字吗？？？

谢谢大家

36 percent of the nation’s 607 HMO’s
中心词是HMO's，复数，所以用were。

estimate sth to be
固定用法

it estimates that this year 73 percent will be
你难道不觉得这句话非常非常非常。。。。。。的不符合语法么？

我不知道他和不合语法，我只知道，答案就是C

sorry, my bad.

if C is the correct answer, i have to say it must have omitted "profitable", but it really sounds weird to me.

E is probably wrong for the pronoun "they".
