定位句：To paraphrase 18th-century statesman Edmund Burke, “all that is needed for the triumph of a misguided cause is that good people do nothing.”引言的含义是：如果好人什么都不做，那么被误导的事业就会取得胜利。紧接着第二句就指出：现在就出现了这样一个被误导的事业One such cause now seeks to end biomedical research 。言外之意就是“好人需要做些事情”，那么好人指代的什么人呢，从下文可以看出是科学家。所以题干问的作者使用这个引言的目的是什么?答案应该是[A] call on scientists to take some actions。
