问题 When a psychologist does a general experiment about the human mind, he selects people______ and asks them questions.

选项 A、at length
B、at random
C、in essence
D、in bulk

答案B

解析题意是：当一个心理学家做一个关于人类心理的一般实验时，他 ______ 选择人群并问他们问题。[B] at random“随机地”，符合题意。[A] at length“终于，详尽地”，[C] in essence“本质上”；[D]in bulk“大量地，成批地”，根据常识，题目要强调的不是选择的人的数量上的多，而是强调选择的方式。因此，这三项都不符合题意。
