5. Some people have questioned why the Homeowners Association is supporting Cooper¡’s candidacy for mayor. But if the Association wants a mayor who will attract more businesses to the town, Cooper is the only candidate it could support. So, since the Association is supporting Cooper, it mist have a goal of attracting more businesses to the town. The reasoning in the argument is in error because (A) the reasons the Homeowners Association should want to attract more businesses to the town are not given (B) the Homeowners Association could be supporting Cooper¡’s candidacy for reasons unrelated to attracting businesses to the town (C) other groups besides the Homeowners Association could be supporting Cooper¡’ s candidacy (D) the Homeowners Association might discover that attracting more businesses to the town would not be in the best interest of its members (E) Cooper might not have all of the skills that are needed by a mayor who wants to attract businesses to a town

答案是D, 但是想不明白B错在哪里?

我是这样想的。

B的意思是，Association选Cooper有可能是因为与Attracting Business无关的事情，言外之意，选Cooper不是为了Attracting Business

D的意思是，Attracting Business不是他们最为关注的问题。但是，可以体会到，Attracting Businesses 是，但不仅仅是他们所关注的。

这样看来，B是与条件冲突的，而D揭示了结论的错误。B是否定，D是递进

这只是我的想法，不知道说明白了没有。也许不对，仅供参考。如果有nn发现了更好的解释，恳请指正。
