标题: 急问：Q40 GWD-24-37.（CD-10-37）
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.

答案是E

个人觉得答案应该是B 请大家帮忙

Profit=sale-cost(fish cost+business expense)
结论是city 的profit margin 更大，就要搞清楚2个因素， sale 增加或者cost减少

文中说原因city : cost 下降，利润增加就必须在sale不降的前提下，

所以要搞清楚是否Sale不降，也就是单价*总数的问题。

B 毫无相关吧，焦点不在这里。
