Question

英语问题
The residents, _________ had been damaged by the flood, were given help by the Red Cross.
A) all of whose homes B) all whose homes C) all their homes D) all of their homes
答案是B,详细解答,越详细越好,半懂者勿回
答案是A，打错了

Answer 1

A) all of whose homes
主要是要明白,句子的来历.
All of the residents' homes had been damaged by the flood.
They were given help by the Red Cross.
所有的居民的家,都已经被洪水破坏了.
他们都被红十字会给予了帮助.
把这两个句子合一起,就要用定语从句.
就变成了,那些居民,（他们所有人的家——这就是定语从句部分）都已经被洪水破坏了,被红十字会给予了帮助.
这样,就应该理解关系了,all of whose homes
