问题 ______ the reactions of people with this drug, scientists have learned more about the brain.
选项 A、By studying
B、To study
C、They study
D、They’re studying
答案 A
解析 by意为“通过、靠(……方式、手段)”，所引导的从句作表方式状语，同样的句子还有：What do you mean by opening my drawer?(你把我的抽屉打开是什么意思?)B的不定式相当于in order to，与下文不符合。C和D都是主语加谓语的结构，填入空中构成两个句子，显然不对。
