标题: 求教GWD一道逻辑题目的解释啊~~
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 county’s “Report on Tourism” must be in error in indicating that _______.
A.    more tourists stay in hotel accommodations in Harristown than stay in the Royal Arms Hotel
B.    the Royal Arms Hotel is the only hotel in Springfield
C.    there are several hotels in Harristown that are larger than the Royal Arms Hotel
D.    some of the tourists who have stayed in hotels in Harristown have also stayed in the Royal Arms Hotel
E.    some hotels in Harristown have fewer tourist guests each year than the Royal Arms Hotel has
哪位大牛给我解释一下为什么选B呢。。。

两个事实:
1.S镇住宿的游客比H镇多
2. H镇最大的旅店住宿的旅客比S镇的RA旅馆多
结论S镇(RA旅馆+其他旅馆)游客人数>H镇(最大旅馆+其他旅馆)住宿人数总和

B选项S镇只有一家RA旅馆,公式变为 S镇(RA旅馆)游客人数>H镇(最大旅馆+其他旅馆)住宿人数总和,
无法成立

因此为B

S说S>H
H说H的largest hotel>S的RAH

如果两个都成立,那么S必然有两家以上酒店。

那为什么要说the county’s “Report on Tourism” must be in error in indicating that
我很不理解这话跟答案怎么连起来的,直接说which one supports the argument,这个report哪里错了,前面根本没提到
问题很奇怪,但是我就是想不过来

the county’s “Report on Tourism” 是一种新的杂志,只是代表新观点的载体,并无实际含义
题目的思路在于如何通过已知的条件进行推论
