Though all the subjects were drawn from a population of European extraction, care was taken to__that all subjects

　　[A] see

　　[B] show

　　[C] prove

　　[D] tell

本题为单选题，请选出正确答案，谢谢！

[A] see

【解析】此处考察动词，动词势必要看前后搭配。see that 构成固定词组，意为“务必使……”，符合文意，即：即使所有的受访者都拥有欧洲血统，(研究者们)仍然悉心确保所有的受访者、朋友和陌生人都来自于同一群种。选项B“展示”,选项C“证明”，选项D“辨别”均无此含义，且不符合文意。
