单选题
Since examples can be
adduced
to support almost any argument, and a set of cases can be
plundered
to provide examples for whatever argument one happens to be pressing, testing a theory requires more than the marshaling of striking examples or the stringing together of case studies.
【正确答案】
A
【答案解析】解析：题干中主语为“example”，结合各选项，只有cite和set两词可与之搭配。而set an example这一短语的含义为“为……做榜样”，不符合题意。因此答案选Cite，引用例子。用排除法即可确定A为正确答案。
