Answer 1

Two decades______really a long time to wait, how will you manage to do that?

A is
B has been
C were
D have been

答案：A
解析：
二十年是一段很长的时间，你将如何办到呢?

Answer 2

A
后句很明显提醒你是将来时
to wait 也表示动作还没做
过去式和完成时的答案肯定就不对
而is既可以是现在是 有时候也表示即将要做的动作

二十年是在是一段很久的等待，你准备要怎么做？

Answer 3

首先是: 你打错了两个字 ades 和 manager，应该是 decades 和 manage 十年叫做一个decade，two decades 即二十年。

所以是: Two decades__is_really a long time to wait, how will you manage to do that.
二十年是一段很长的时间，你如何可以办到? a long time 不可数要用 is (is a long time)。

Answer 4

排除法，ades是复数，A，B单数形式肯定不对，C是过去式也不对，整个句子的语态是一般现在时，过去式肯定不合适。这样就只有D符合题意。

Answer 5

A is
