It is impossible to measure the importance of Edison by adding u

It is impossible to measure the importance of Edison by adding up the specific inventions ______ his name is associated.
A、about which
B、with which
C、of that
D、on that
【正确答案】：B
【题目解析】：本题考查定语从句中介词前置。前置的介词由句中谓语动词决定,associate后跟介词with,故只能选B。该定语从句等同于：...inventions which/that his name associates with。但当介词提到关系代词前时，就不能用that了。题意为：仅仅把和他的名字爱迪生有联系的种种发明加起来，这样是无法衡量他的重要作用的。答案为B。
