标题: 大全-B-17

17.   Ronald: According to my analysis of the national economy, housing prices should not increase during the next six months unless interest rates drop significantly.

Mark: I disagree. One year ago, when interest rates last fell significantly, housing prices did not increase at all.

It can be inferred from the conversation above that Mark has interpreted Ronald’s statement to mean that

(A) housing prices will rise only if interest rates fall

(B) if interest rates fall, housing prices must rise

(C) interest rates and housing prices tend to rise and fall together

(D) interest rates are the only significant economic factor affecting housing prices（B）

(E) interest rates are likely to fall significantly in the next six months

问题到底是问的什么啊？总感觉答案不对

你说的我懂，但是提干上说的是 did not increase at all，而B说的是 housing prices must rise，很明显忽略了价格不变的情况阿！fficeffice" />

答案选B吧，这题没有什么问题啊，纯粹的是充分与必要条件在这瞎搞

楼主问的是：这道题的问题问的是什么？

我的理解是：问Mark把Ronald的话理解成什么意思了。

类似的逻辑题在LSAT中不少，但GMAT中好像不多。
