A.    had expected it to and its business will improve
B.    had expected and that its business would improve
C.    expected it would and that it will improve its business
D.    expected them to and its business would improve
E.    expected and that it will have improved its business

答案没有问题，但是关于WOULD 和 WILL 的区别反而有点想法了，想和大家一起研究。
这里OG 提到： uses “would” rather than “will” to refer to a promised but uncertain future event.这种区别是否能为我们用来判断选项呢？

顺便有个个人总结，希望大家看看是否正确。
在从句里是否不能使用 future perfect tense。如E这样的句型必错。
