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(C) some Tri-Cities High School students have withdrawn from Camp Lakemont

(D) all Tri-Cities High School students have withdrawn from Camp Lakemont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

答案E,不知道怎么推出.

9. Governments have only one response to public criticism of socially necessary services: regulation of the activity of providing those services. But governments inevitably make the activity more expensive by regulating it, and that is particularly troublesome in these times of strained financial resources. However, since public criticism of child-care services has undermined all confidence in such services, and since such services are socially necessary, the government is certain to respond.

Which one of the following statements can be inferred from the passage?

(A) The quality of child care will improve.

(B) The cost of providing child-care services will increase.

(C) the government will use funding to foster advances in child care.

(D) if public criticism of policy is strongly voiced, the government is certain to respond.

(E) If child-care services are not regulated, the cost of providing child care will not increase.

答案B,求教,我选E

2.。关键对答案E的理解，他的意思为：All Tri-Cities High School students are campers at Camp Winnehatchee (only A is B相当于all B is A)。也即BILL将ANN的话理解成E（ANN的话的逆命题）。

9。原文的逻辑为：政府的行为是：有批评且是necessary 活动，政府就REGULATING，有REGULATING活动就more expensive 。在原文的CHILD-CARE例子中，具备了批评且是necessary 的条件，所以当然more expensive 。即B。E为否命题，故错

这题还是不是很明白,(only A is B相当于all B is A),是一条逻辑定理吗?TO LAWYER,你的意思是说题目和答案其实是同一个意思吗?唉,我都绕晕了.
