单选题 Advertisement:
The world's best coffee beans come from Colombia. The more Colombian beans in a blend of coffee, the better the blend, and no company purchases more Colombian beans than Kreemo Coffee. Inc. So it only stands to reason that if you buy a can of Kreemo's coffee, you' re buying the best blended coffee available today.
The reasoning of the argument in the advertisement is flawed because it overlooks the possibility that

A、 the equipment used by Kreemo to blend and package its coffee is no different from that used by most other coffee producers.
B、 not all of Kreemo's competitors use Colombian coffee beans in the blends of coffee they sell.
C、 Kreemo sells more coffee than does any other company.
D、 Kreemo's coffee is the most expensive blended coffee available today.
E、 (E) the best unblended coffee is better than the best blended coffee.

【正确答案】 C

【答案解析】[解析] 本题属于“逻辑应用与技法”题型。推论的大前提是“混合咖啡中含有的哥伦比亚咖啡豆越多，则此混合咖啡就越好。”如果Kreemo比其他公司销售更多的咖啡，如(C)所说，那么即使Kreemo买的哥伦比亚咖啡豆最多，一罐Kreemo的咖啡里面含原哥伦比亚咖啡豆的量可能并不是最多，因此其混合咖啡最好也就受到了质疑。所以(C)通过指出上面推理的这种可能性从而说明上面推理是有缺陷的，因此(C)正确；(A)的“no different from”说的是共同点，多出现在support类的答案中；(B)中的并非所有“Kreemo的竞争对手”什么也说明不了，所以为无关选项；(D)中的expensive并不等于“the best”，所以也为无关选项；(E)是一个典型的无关比较，因此也不对。
