GWD-6-Q26:

Tourists have long complained that hotel accommodations in Midville are too expensive.  Starting last year, the city council, hoping to attract more tourists, lowered the hotel tax rate to 5 percent of room charges.  By the end of last year, Midville had taken in no less money from hotel taxes than it did the year before, so an examination of the hotel records will show that more tourists stayed in city hotels last year than the year before.

Which of the following is an assumption on which the argument depends?

A  The tourists who stayed in Midville hotels last year were aware that the hotel tax rate had been lowered.

B  The average price of hotel accommodations in Midville was not significantly higher than in hotels in other cities either last year or the year before.

C  The average length of a tourist’s stay in Midville hotels was not longer last year than it had been the year before.

D   There were significantly more efforts to publicize Midville as a tourist destination last year than there had been the year before.

E   On average, tourists in Midville did not spend significantly more on meals last year than they did on hotels accommodations.

答案C。为什么A，B错？

旅客抱怨宾馆太贵。

last year，降低了房间的消费税到5%        

end of last year,  税 >   the year before , 税  ---M 从宾馆取得的税收不比  the year before少

 所以 ，last year  tourist ， 多，>  the year before  tourist

如果C捂住not (没有not), 还有可能，没有not ---旅客呆在宾馆的平均时间去年（last year）比前年(the year before)长。

如果C有not ，那C怎么能够是假设呢？

totaly 不能理解

谢谢

谢谢楼上的回复,很遗憾后几个关键的字竟是乱码

还是不清楚，真愚的我还要继续请教，谢谢

去年旅客平均入住的长度短，比前年--是这个意思吗？ 我是不是理解错了？

如果是，那么说明旅客流量大，降低税没有吸引旅客--那么与结论“more tourists stayed in city hotels last year   than the year before.” 相反， 应该不能构成假设？为什么？

啊，是不是因为旅客流量大，就代表吸引了更多游客了？

你理解的对阿

C项中去年旅客入住的时间没有前年长， 取非的就是去年的旅客待的时间比前年长，也就是说时间长了，但人数没有增加。

平均价格是一个新概念，跟收入无关，如果相关的话还要考虑旅客人数的变化，

所以单平均价格不足以作前提

入住时间是一个比较直观的前提

你这样说有误导性

ASSUMPTION里有没有引入新概念并不能作为判断依据.B错是因为平均价格去和其它城市比,这是无关比较.如果B选项改成平均价格比以往的平均价格都高,那就是正确答案了(改写后取非是削弱,所以是正确答案).

我对这题可以这样理解:

平均税收总价=平均价格 X 平均天数 X 平均每天客户人数 X 税金百分比

在知道税收百分比降低且平均税收总价不变的条件下, 潜在的条件就是平均天数(选项C) 平均价格(选项A改写)和平均人数这3个里有至少有一个要降低.

对c取非，去年的确比前年长，对原文起到了削弱的作用。所以选C.

注意：对于assumption的题，如果没有明显的gap，那么就用上述方法。
