下一道根本看不懂呀，求解释


103.    (31044-!-item-!-188;#058&005684)    (GWD 6-Q28)

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

Which of the following most logically completes the argument below?

Twenty percent of the stores in Morganville's downtown shopping district will fail within five years because they will be competing directly with the SaveMart discount department store newly opened in East Morganville.The downtown shopping district has lost business at this rate before and has always completely rebounded. Confidence that it will rebound again from the losses it is now about to suffer is ill founded, however, because __________.



A. the stores likely to be put out of business by direct competition from SaveMart are the downtown shopping district's anchor stores, on whose ability to draw shoppers many of the other downtown stores depend

B. the bus line that has long connected the downtown area of Morganville with East Morganville has a tradition of carrying shoppers who reside in East Morganville into downtown Morganville to shop

C. when the downtown shopping district has rebounded before, the business premises of a failed business were typically taken over by a business of the same kind as had been there before

D. SaveMart's business plan for the East Morganville store is based on earning low profits, if any, during the first five years of the store's existence

E. it is conceivable that the downtown shopping district could shrink substantially without collapsing altogether

能不能解释一下，逻辑链，看不懂呀，伤不起

以前商店销售下降 大能够恢复；所以原文结论是这次的下降也能得到反弹；问为什么这样推测不对...那答案的要点应该是现在的状况和以前有些什么变化....所以答案应该是C

ls说了77
拿我来说103好啦><抛个砖~

就是说
S>H ------
且
H最大的【设为L】比S的某个酒店多，即，
R<L-------

问题是哪一个是错的~
那就是说【 哪一个代入会影响这两个不等式的结果】【比如选项的statement为，+会使错误，就选这个选项】
然后E说
R是S的唯一一个酒店，
即R=S--------------

如果+
翻译一下，就是 R=S and R<L, 一个隐含条件是 L<H
得：
R=S<L<H
即S<H
这与矛盾

所以E是in error的哈~

【比如选项的statement为，+会使错误，就选这个选项】

————————————-
这里更正：

【比如选项的statement为“3”，"2+3"会使1错误】

——————————
另外题目的两个结论标为"1" "2"
R=S标为"3"
