LSAT2-2-2 求教

2.     Ann: All the campers at Camp Winnehatchee go to Tri-Cities High School

Bill: That’s not true. Some Tri-Cities students are campers at Camp Lakemont.

Bill’s answer can be best explained on the assumption that he has interpreted Ann’s remark to mean that

(A) most of the campers at Camp Lakemont come from high schools other than Tri-Cities

(B) most Tri-Cities High School students are campers at Camp Winnehatchee

(C) some Tri-Cities High School students have withdrawn from Camp Lakemont

(D) all Tri-Cities High School students have withdrawn from Camp Lakemont

(E) only campers at Camp Winnehatchee are students at Tri-Cities High School

求教此题！看不懂其中的推理：Ann说“所有的在CW的露营者要去TC School”，Bill则说“一些TC的学生是在CL的露营者”如何推出E为假设。

没贴上，再写一遍。

问题问B将A的话理解成下列哪个选项。因为B说THAT IS NOTTRUE。所以选项必须和B的话矛盾，即MUST BE FALSE。BILL说有些TC的学生在L野营。E选项说所有TC学生在W野营。

only A are B=All B are A

收到！多谢lawyer_1的解释！遇上否定就犯晕！
