例2、Even though most universities retain the royalties from faculty members’ inventions, the faculty members retain the royalties from books and articles they write. Therefore, faculty members should retain the royalties from the educational computer software they develop。

　　The conclusion above would be more reasonably drawn if which of the following were inserted into the argument as an additional premise?

　　(A) Royalties from inventions are higher than royalties from educational software programs。

　　(B) Faculty members are more likely to produce educational software programs than inventions。

　　(C) Inventions bring more prestige to universities that do books and articles。

　　(D) In the experience of most universities, educational software programs are more marketable that are books and articles。

　　(E) In terms of the criteria used to award royalties, educational software programs are more nearly comparable to books and articles than to inventions。

　　翻译：尽管大部分大学拥有了他们教员发明的版税，但是教员却拥有他们所写的书和论文的版税，因此教员应该拥有他们所开发的计算机软件的版税。

　　问：下面哪一项作为一个附加的前提被加上的话，上面的结论将会被推出？

　　(A) 发明的版税比教育软件的版税要高；

　　(B) 教员更有可能做出教育软件，而不是发明；

　　(C) 发明带给了出书和文章的大学更高的威望；

　　(D) 大部分大学的经验当中，教育软件比起书和论文更容易市场化；

　　(E) 根据过去给的版税标准，教育软件和书、论文的相似程度比起发明更大一些。

　　分析：这篇文章阅读起来是有困难的，关键是看不懂“书、论文”和“教育软件”之间的关系，但这正是我们要注意的，因为推导缺陷就在于此，假设的答案也就产生于此处。E 选项说明了教育软件和书、论文两者之间的关系，所以是正确答案。
