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 .
A. The average length of stay is longer at the largest hotel in Harristown than it is at the Royal Arms Hotel.
B. There is only one hotel in Harristown that is larger than the Royal Arms Hotel.
C. More tourists stay in hotels in Harristown than stay in the Royal Arms Hotel.
D. The Royal Arms hotel is the largest hotel in Springfield
E. The royal arms hotel is the only hotel in Springfield.
正确答案为E
看晕了，文章的最后一句话，如果两个消息都是正确的，那么为什么又问其中一个错在哪了，，，这个问题就糊涂了。作者: jane.seeker 时间: 2013-8-12 16:27
题目中给出两点：
1. Springfield的住宿游客总数Harristown多。（两城总数相比）
2. Harristown最大的旅馆的住宿游客数比Springfield的其中一家旅馆Royal Arms Hotel的人数要多。（两城各一家旅馆相比）
问题就是：如果1、2两点都成立，那么“有关这两个地区的旅游报告”中怎样的总结是错误的？也就是若1、2都成立，不能推出以下那点？
答案E：S的总数比H多，若R是S唯一一家旅馆，而H的其中一家旅馆都比R多，那么就与“S的总数比H多”相悖。作者: llmmlemon 时间: 2013-8-12 23:01
Report on Tourism for the region并不是前两个消息之一，而是单独的一份报告。作者: MsL 时间: 2013-8-17 20:20
啊~~~~~ 原来是问题看差了。我真的是给理解成了report on tourism for the region是前面那个hotel的report。

我觉得是如果1,2都成立，以下哪点一定错误？
这和“不能推出哪一点”是不同的，楼主体会一下。作者: 典座 时间: 2020-5-29 00:45
