Q39:

Which of the following most logically completes the argument below?

According to promotional material published by the city of Springfield, more tourists stay in hotels in Springfield than stay in the neighboring city of Harristown.  A brochure from the largest hotel in Harristown claims that more tourists stay in that hotel than stay in the Royal Arms Hotel in Springfield.  If both of these sources are accurate, however, the “Report on Tourism” for the region must be in error in stating that ______.

请大侠指教！！！不明白！这道题是啥意思？

我觉得“Report on Tourism”指的就是promotional material published by the city of Springfield, more tourists stay in hotels in Springfield than stay in the neighboring city of Harristown. 题目让我们找一个有错误的选项，E说springfield只有一个hotel，而且根据brochure住的人比harristown的那个少，这样就跟report on tourism相对立，所以不能成立。

不是n人，共同讨论。

请大牛帮帮忙啊！咋做这道题阿？

再次求助此题，之前的帖子没怎么讲明白啊。

Q39:

Which of the following most logically completes the argument below?

According to promotional material published by the city of Springfield, more tourists stay in hotels in Springfield than stay in the neighboring city of Harristown. A brochure from the largest hotel in Harristown claims that more tourists stay in that hotel than stay in the Royal Arms Hotel in Springfield. If both of these sources are accurate, however, the “Report on Tourism” for the region must be in error in stating that ______.

1. the average length of stay is longer at the largest hotel in Harristown than it is at the Royal Arms Hotel
2. there is only one hotel in Harristown that is larger than the Royal Arms Hotel
3. more tourists stay in hotels in Harristown than stay in the Royal Arms Hotel
4. the Royal Arms Hotel is the largest hotel in Springfield
5. the Royal Arms Hotel is the only hotel in Springfield

答案选E，我觉得几个答案都对不上。请大家指教。

其实很简单 题目说Report on Tourism有错误 那么本题的答案需要找一个必要条件使得原文的论述有明显错误！

E选项说明 Royal Arms Hotel是Springfield的唯一  也就是说去Springfield旅游的肯定住在Royal Arms Hotel

将其带入原文看看

在原文中说more tourists stay in hotels in Springfield（也就是Royal Arms Hotel） than stay in the neighboring city of Harristown这个假设正确 那么hotel in Harristown claims that more tourists stay in that hotel than stay in the Royal Arms Hotel in Springfield如果也正确 两种论述完全相反! 

所以Report on Tourism报告可能错误地声明了E的内容 也有可能是其他方面出了问题，但美国人想问题不需要充分性，他们觉得“有这个可能性”就行了

另有两题是我评述 可以加深对“非充分性”的理解
