The time is soon coming ---the news will be made known ---wi

其实这个题主要是看后一空就可以了.
---will be sent abroad for further study.
（ ）被派到国外深造
说明一定是人,而且是作宾语,显然是填who,后面是who的只有B,
为什么不是whoever,逻辑不符,任何人都出国深造,谁守家呢?
The time is soon coming (when-)-the news will be made known -（who）-will be sent abroad for further study.
译：当这个消息被公布的时候到来时,他（她）将被派到国外学造.
