第二题的C中that指代有问题。a substitute for the telephone和a tool for private conversation是同一个事物，所以应该用同位结构，而不是C中的定语从句结构（修饰作用）

Many people can't conceive of a dinner without meat or fish.
conceive that
He could not conceive that anything really serious could be worrying his friend.
conceive what/why/how etc
I can hardly conceive what it must be like here in winter.
conceive of something/somebody as something
Language may be conceived of as a process which arises from social interaction.

是不是可以认为conceive of后面加as是正确的用法呢？

还请指点

BCE

老美解释太精辟了。全用排除法

第二题的C中that从句没有有问题，E的other than what it is,的,不妥。

第三题的C中was要改成is,D中的award后面必须要逗号
