【答案】C

　　【解析】考查强调句型和名词从句。句意：直到天黑，他才发现他认为正确的解决问题的方法。分析句子可知，后面的he found的宾语从句子缺少主语，缺少主语要用what，所以本句中要有一个what。B项是错误的。题目中含有It was，出现这样的结构，首先要考虑它是不是强调句。如果把这种句型结构划掉后，应该是一个完整无缺的句子；这也是判断强调句型与其它从句的方法。假设它是强调句，去掉it was和空格处，剩下的句子not until dark he found what he thought was the correct way to solve the problem经过调整语序后是一个完整的句子，所以是强调句型。故A、D不正确。因此C是正确的。
