B选项看不出有什么明显的支持, E选项很明显,在实验中加入了一种CHEMICAL,如果这种CHEMICAL本身就能抑制食欲,就不能说是CAN...抑制食欲,所以必须前提假设这种加入的CHEMICAL并没有抑制食欲的功能 -- by 会员 Rebeldom (2010/5/10 11:40:16)
哦哦。。知道了。。谢谢哈! 还有一题能帮忙看下嘛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. | | | more fish wholesalers are located within the city than in the surrounding suburbs. | | | | Any people who currently own seafood stores in the suburbs surrounding Eastville will relocate their businesses nearer to the city | | | | The wholesale price of fish is likely to fall in the future | | | | Fish has always cost about the same at seafood stores throughout Eastville and its surrounding suburbs. | | | | Seafood stores within the city will in the future set prices that are lower than those at suburban seafood stores. 我感觉D说的是鱼的成本一样,那一样的话,那个税少了,利润就自然增加了嘛,E就不一定了,鱼的价格低了,因此利润不一定会高吧 |
