问题补充：

The people， had been damaged by the flood，were given help by the Red Cross.

A. all whose homes

B. all their homes

C. all of their homes

D. all of whose homes

答案：

A. all whose homes

B. all their homes

C. all of their homes

(答案→)D. all of whose homes

解析：分析句子成分可知，空格以及空格后的部分应该是一个非限制性定语从句，whose在从句中作定语，修饰名词homes，注意all不可直接用在whose前。
