Fish currently costs about the same at seafood stores throughout Eastville and its surrounding suburbs. Seafood stores buy fish from the same wholesalers and at the same prices, and other business expenses have also been about the same. But new tax breaks will substantially lower the cost of doing business within the city. Therefore, in the future, profit margins will be higher at seafood stores within the city than at suburban seafood stores.

For the purposes of evaluating the argument, it would be most useful to know whether

A.more fish wholesalers are located within the city than in the surrounding suburbs.

B.Any people who currently own seafood stores in the suburbs surrounding Eastville will relocate their businesses nearer to the city

C.The wholesale price of fish is likely to fall in the future

D.Fish has always cost about the same at seafood stores throughout Eastville and its surrounding suburbs.

E.Seafood stores within the city will in the future set prices that are lower than those at suburban seafood stores.

我在其他网站上又找到，选D和E的人都有，我觉得两个都可以啦~所以想问下应该选什么。谢啦谢啦！！！

E should be the answer since it mentions PRICE instead of COST. To get a number for margins, you need botth selling price and cost.

D only repeats the first sentence of the stimulus. Thus it would not help us evaluate the situation.

谢谢啦~还有我想问一下，我做逻辑看的懂题目和选项，可是就是选不对答案，这个怎么提高呀？

sdcar2010

Perhaps you need to know more about the fundamentals of logical reasoning. For example, what is the premise? The conclusion? The assumption? The common fallacies?
