--Why was the official meeting called?

问题描述:

--Why was the official meeting called?
--_____new officers.
A.Select B.SelectingC.To select D.To have select
为什么不能填写D项呢?不是过去式吗?
答句要是写全了是什么样子呢?
请翻译一下Why was the official meeting called?是什么意思?

Why was the official meeting called?为什么召开官方(正式)会议?
答案应是to select(意思是,为了选举新官员)
而D to have select 一是它啥形式也不对,而是即使select加了ed,也表示已经过去.根据上下文看,select 的动作还没发生.
