问题 单项选择题

研究人员对75个胎儿进行了跟踪调查,他们中的60个偏好吸吮右手,15个偏好吸吮左手。在这些胎儿出生后成长到10到12岁时,研究人员发现,60个在胎儿阶段吸吮右手的孩子习惯用右手;而在15个吸吮左手的胎儿中,有10个仍旧习惯用左手,另外5个则变成“右撇子”。

从这段文字中,不能推出的是()。

A.大部分人是"右撇子"

B.人的偏侧性随着年龄的增长不断改变

C.大多数人的偏侧性在胎儿时期就形成了

D.左撇子可能变成"右撇子",而"右撇子"很难变成"左撇子"

答案

参考答案:B

解析:

题中的75个婴儿在长大后偏侧性发生变化的只有5个,说明大部分人的偏侧性并不会随年龄的增长而变化,B不能从正文中推导出来。故正确答案为B。
