另外一道很蒙的逻辑题目, 请求帮忙.

Although gaining expertise in using online databases is valuable in helping journalism students to develop research skills, some popular internet  sites are full of misinformation. In many cases, when journalism students get their information from the Internet,  they do not confirm the accuracy of this information. Thus, journalism students who get the majority of their information from the Internet are more likely to write articles containing factual errors than are journalism students who get their information from other sources.

The argument depends on which of the following assumptions?  

A Watching the news on television does not hinder the development of journalism students' research skills.
B When writing dissertations, most journalism students check the accuracy of Internet-based information.
C Journalism students who don't use the Internet to do research for articles check the accuracy of their information.
D Formal instruction in research techniques contributes little or nothing to journalism students' acquisition of research skills.
E The research skills developed using the Internet do not contribute significantly to journalism students' overall development as journalists.

答案是C, 但是如果对C 取非,

如果information from other sources doesn't contain any factual errors, C 也不能否定结论啊. 求助求助.

取非一般是对一个句子的谓语取非 对C取非 Journalism students who don't use the Internet to do research for articles （do not） check the accuracy of their information. 这些同学就是用other source的人，如果对other source的info.也不检查它的正确性，不就和到internet上查的人一样了， they do not confirm the accuracy of this information，对原文形成削弱

很明显是C啊

多谢LS 回答, 最近脑子实在是死机了.....

这里说 journalism students who get the majority of their information from the Internet are more likely to write articles containing factual errors than are journalism students who get their information from other sources.

我的理解是假设是没有说出来但是必须的条件.
C 说从其他地方获取信息的学生检查信息的真实性.  原文只是说了从网络获取的信息很多不真实.

如果从其他地方获取的信息都是真实的, 那么C就是不必要的条件了, 因为检不检查最后的文章包含的都是真实信息啊.

实在是脑子晕了........唉,
