(单选题)

Which of the following is true according to Greg Bryant?

A.Real laughter is not at all controllable by our brain.

B.People may notice fake laughter without knowing why.

C.People use the same set of muscles to laugh and to speak.

D.Faking laugh shares the same techniques as making speech.

参考答案：B

参考解析：

推理判断题。根据第四段第二句“The result is that there are subtle features of the laugh that sound like speech, and … people are unconsciously quite sensitive to them.”可知，其结果是，笑声中有一些微妙的特征，听起来像在说话，而且……人们在不知不觉中对它们相当敏感。由此可推知，根据Greg Bryant的说法，B选项“人们可能会在不知道原因的情况下注意到假笑声”正确。故选B。
