Question

Boris has brains. In fact, I doubt whether anyone in the class has ________ IQ.

1. A.
   a high
2. B.
   a higher
3. C.
   the higher
4. D.
   the highest

Answer 1

B
解析：
形容词比较级前用不定冠词，后接可数名词单数，a或an虽然表示泛指，但在特定语境中表示最高级的概念．IQ是“智商(intelligence quotient)”缩略，其后省略了than he has．应用a higher与anyone一起泛指全班没有一个智商高于他的，验证前句的“头脑灵，智商高”．
