Marconi’s conception of the radio was as a substitute for the telephone, a tool for private conversation; instead, it is precisely the opposite, a tool for communicating with a large, public audience.

D.      Marconi conceived of the radio to be a tool for private conversation, a substitute for the telephone, which has become

E.       Marconi conceived of the radio to be a substitute for the telephone, a tool for private conversation, other than what it is,

纠纷在B，C选项上，我的答案版本是C，而我选的B，说a tool for private conversation 逻辑上是修饰radio的，但是在B中修饰了telephone. 而C中conceived of the radio as a tool for private conversation that could substitute for ....that 不是应该就近修饰conversation吗？最近遇到好多类似的问题，就是that 是否就近修饰的问题，什么中心词什么的，很混。但是看了答案后我觉得B的问题好像比较多，but which is 这个结构很怪，在这个位置没有准确的指代。还有这道题到底选什么啊？讨论版中答案也不确定，BC之争

同问。
