问题 单项选择题

左撇子的人比右撇子的人更经常患有免疫功能失调症,比如过敏。但是左撇子往往在完成由大脑右半球控制的任务上比右撇子具有优势,并且大多数人的数学推理能力都受到大脑右半球的强烈影响。
如果以上信息是正确的,最能推出下面哪个结论
Ⅰ.患有过敏或其他免疫功能失调症的人中,左撇子比右撇子多。
Ⅱ.在所有数学推理能力强的人当中左撇子的比例,高于所有数学推理能力弱的人当中左撇子的比例。
Ⅲ.在所有左撇子中,数学推理能力强的比例,高于数学推理能力弱的比例。( )

A.仅Ⅰ。

B.仅Ⅱ。

C.仅Ⅲ。

D.仅I和Ⅲ。

答案

参考答案:B

解析:

[分析]: Ⅰ不能从题干中推出。因为虽然左撇子的人比右撇子的人更经常患免疫功能失调症,但也许在整个人群中左撇子的绝对数量很小。因此即使他们全都患上免疫功能
失调症,也未必是个庞大的数字。
Ⅱ能够从题干中推出。因为否则的话,题干中所表达的左撇子比右撇子在数学上有优势的观点就不成立了。
Ⅲ不能从题干中推出。因为题干中所给出的,是关于左撇子和右撇子相比较而得出的一些信息,而Ⅲ则是关于左撇子人群内部的信息,显然不能从题干中推出。
所以,选项B是正确答案。
