Question

【题目】The new buyer identified a dozen new sources for the material, ________ proved to be reliable.

A.most of themB.most of whichC.most whomD.most of those

Answer 1

【答案】B

【解析】

考查定语从句。句意：新买主为这种材料找到了十几个新的来源，其中大多数被证明是可靠的。本句为“介词+关系代词”结构的非限定性定语从句修饰先行词the material，且先行词做介词of的宾语，指物故应用关系代词which。故选B。
