Many of today’s mathematicians use computers to test cases that are either too time-consuming or involve too many variables to test manually, allowing the exploration of theoretical issues that were impossible to test a generation ago.

这道题Po选了E,现在看来发现但是忽略了much 修饰variables,但是还是觉得C有点不对C的主干是: Many of today’s mathematicians use computers, allowing them to explore...
这里allowing修饰Use逻辑主语是many mathematicians,但是them应该指代mathematicians,那这样不就成了mathematicians allow mathematicians.... 好奇怪啊..
