evidence 2: more tourists stay in the largest hotel in Harristown than stay in the Royal Arms Hotel in Springfield.


If both evidences are true, which one of the following is false?
(B) is incorrect because there must be more than one hotel in Springfield.

楼上神马意思？没看懂，求救大神们

半阙

这题貌似选E啊
evidence1:S地旅馆的游客比H地旅馆的游客多
evidence2:H地最大的旅馆比S地R旅馆拥有的游客多
最后一句的意思实际上是：基于以上两个成立的事实，Report一定是错的如果它state......
不就选E了么？~

这题我也错了，他问的很有歧义有木有？~什么叫“must be in error in stating that”？如果改成“must be error in stating that”不就皆大欢喜了么？   我开始一直以为问文中的某个flaw，搞得我研究了半天很不淡定的发现这两个evidence并没啥矛盾.....

倚柴

我觉得...是不是这样：

问题问的是，在以上两个现象：
evidence 1: more tourists stay in hotels in Springfield than stay in Harristown.
evidence 2: more tourists stay in the largest hotel in Harristown than stay in the Royal Arms Hotel in Springfield
都是正确的情况下，以下的情况哪个是错误的
即RAH是S的唯一酒店，肯定是错误的 不然S的游客就不会比H多
所以答案还是B.....不知道是不是这样啊....

From the stimulus, we know two facts:
(1) More tourists stay in hotels in Springfield than in neighboring city Harristown
(2) The largest hotel in Harristown claims that more tourists stay in there than in the Royal Arms Hotel in Springfield

Both facts are true.  Then the stimulus says that "Report on Tourism" must be wrong by saying the blank (our answer choice).  Apparently the Report must have said something controdictory to the two facts we just learnt.

Answer choice (B), "the Royal Arms Hotel is the only hotel in Springfield" is correct answer to fill in the blank because if (B) is true, then Fact (2) is true but Fact (1) must be false.

是B是B~我弄错了，我做的那个版本E答案就是这里的B~

我也选B。

According to the argument:
statement (1): tourists @ Springfield  >  tourists @ Harristown
statement (2): tourists @ the largest hotel in Harristown > tourists @ Royal Arms Hotel

Common sense: tourists @ Harristown > tourists @ the largest hotel in Harristown

If the county's "Report on Tourism" indicates that Royal Arms Hotel is the only one hotel in Springfield,

we can get: tourists @ Springfield = tourists @ Royal Arms Hotel


[PROVE 1]:

statement (1): tourists @ Springfield > tourists @ Harristown

Substitute [tourists @ Springfield] for [tourists @ Royal Arms Hotel]

Then, the statement (1'): tourists @ Royal Arms Hotel > tourists @ Harristown

Common Sense: tourists @ Harristown > tourists @ the largest hotel in Harristown

Combine the statement (1')  with our common sense:  
tourists @ Royal Arms Hotel > tourists @ Harristown > tourists @ the largest hotel in Harristown

Therefore, tourists @ Royal Arms Hotel > tourists @ the largest hotel in Harristown

Conflict with statement (2): tourists @ the largest hotel in Harristown > tourists @ Royal Arms Hotel


[PROVE 2]:

statement (2): tourists @ the largest hotel in Harristown > tourists @ Royal Arms Hotel

Substitute [tourists @ Royal Arms Hotel] for [tourists @ Springfield]

Then, the statement (2') would become:  tourists @ the largest hotel in Harristown > tourists @ Springfield

According to our common sense: tourists @ Harristown > tourists @ the largest hotel in Harristown

Combine the statement (2')  with our common sense:
tourists @ Harristown > tourists @ the largest hotel in Harristown > tourists @ Springfield

We can get: tourists @ Harristown > tourists @ Springfield

Again, conflict with statement (1): tourists @ Springfield  >  tourists @ Harristown


SUMMARY:  If Royal Arms Hotel is the only one hotel in Springfield, either statement (1) or statement (2) must be false. #

What a tricky question!!

答案就是选B啊。S城市住的旅客比H城市的多，但是H城市里面一个旅馆却说住他们酒店的客人比S城市一家旅馆的多，那么就证明S城市那家旅馆肯定不是唯一的。要是唯一的都比它少，那总数怎么可能比人家多呢？
