问题 单项选择题

只有计算机科学家才懂得个人电脑的结构,并且只有那些懂得个人电脑结构的人才赞赏在过去10年中取得的技术进步。也就是说只有那些赞赏这些进步的人才是计算机科学家。
下面哪一项,最准确地描述了上述论述中的推理错误

A.上述论述没有包含计算机科学家与那些赞赏在过去10年中取得技术进步的人之间的明确的或含蓄的关系。

B.上述论述忽视了这样的事实:有一些计算机科学家可能并不赞赏在过去10年中,取得的技术进步。

C.上述论述忽视了这样的事实:计算机科学家除了赞赏在过去10年中取得的技术进步之外,还会赞赏其他事情。

D.上述论述的前提以这样的方式来陈述:即它们排除了得出任何合乎逻辑的结论的可能性。

答案

参考答案:B

解析:题干论述可整理简化为:因为只有科学家才赞扬技术进步,所以不赞扬科技进步的人都不是科学家。但是,请注意,“科学家”是“赞扬科技进步”的必要条件,而不是充分条件,就是说不赞扬科技进步的未必就不是科学家——这正是题干论述的逻辑漏洞。 B项指出了这一错误。
