标题: Prep逻辑一道，求教
不懂

premises: 1) SF promotion: more ppl stay in SF (Springfield) than in H (Harristown)
2) brochure from biggest hotel in H: more ppl in this hotel than in RA hotel in SF.
3) both right.

what mistake was made..

A) irrelevant: the length of stay
B) irrelevant: the size of the hotel
C) it is truth, not mistake. coz the biggest hotel in H already has more visitors than RA hotel. therefore, the combined number of visitors in hotels in Harristown must be greater than number of ppl in RA hotel.
D) irrelevant+unknown
E) Correct. if RA is one of the hotels in Springfield, the total will accomodate more ppl in SF.

hope it helps

今天有看了一遍这个题，发现还是错了~~~
（1）more people stay in SF than H, 也就是说在SF的人要比H多，H<SF
（2）H最大的酒店住的人比SF的RA酒店里住的人多，然后呢？H>SF
这怎么能推出来RA是唯一的酒店呢？如果RA是唯一的酒店，可是RA住的人比H最大的酒店住的人还少，也就是说H最大的酒店比RA人多，这就不符合第一条了

求指教！
