there is not any difference between the two,l really do not know ( )

问题描述:

there is not any difference between the two,l really do not know ( )
A which to choose from B which to choose
求英语帝解释 区别两者

A选项的which to chose from中的which做的是定语 B中的which做的是宾语 而此题缺少宾语还是没懂....choose from 是选择范围,而choose是从范围中选择,此题应该是从这两个中选择一个指定的对象
