There is hard evidence George has something to do with the murder.
A. which
B. what
C. why
D. that

A. whichB. whatC. why(答案→)D. that解析：同位语从句属于名词性从句，大多由从属连词that引导，常常跟在fact, news, idea, thought, question, reply, report, remark, hope, belief等名词后面。同位语从句一般用来解释或说明这些名词的具体含义或内容，在逻辑上表现为同位关系。同位语从句与that引导的定语从句：（1）从先行词看，同位语从句与名词之间在逻辑上是“主语+be+表语”的同位关系。该名词是需要作特殊说明的抽象名词。例如：They were delighted at the news that their team had won. The news was that their team had won. (2)从引导词来看， 引导词that在同位语从句中是连词，只起连接作用，无具体词义，that不可省略；that在定语从句中是关系代词，它在从句中充当一定成分——主语或宾语，有具体词义，作宾语时还可以省略。(3)同位语从句的简易判断方法，同位语从句与其先行词在逻辑上是“主语+be+表语”的同位关系。所以，可以在名词和从句之间加系动词be，使之构成一个新句子，如果合乎逻辑，句子通顺，则原句为同位语从句；定语从句是不能够用系表结构把先行词与从句连接起来的。本题中的同位语从句that George has something to do with the murder用来解释名词evidence的内容，that在同位语从句中不充当任何成分，只是一个引导词而已。句义：有证据显示乔治和这起谋杀案有关。故D正确。
