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) the best unblended coffee is better than the best blended coffee

答案是c!但是c好像说的是：k公司比别的公司coffee卖得多，和题干的结论好像无关呀！另外，a为何不对，我理解的是因为k公司和别的公司用的设备包装一样，因此，尽管，k公司比别的公司coffee豆买得多，也不能说消费者买k公司的coffee,就买到了最好的coffee！

请大侠们指点！

我觉得a不对,因为题中k公司的coffee好是因为用了更多的coffee bean.设备同,但是COFFEE BEAN用的数量不同,会影响coffee质量的. C中说的就是因为K公司卖的数量多,所以并不能说明coffee里面的BEAN用的多,也就不能证明K公司的coffee好了!

题意：哪个牌子的咖啡用C咖啡豆越多，那个牌子的咖啡豆就越好。而K公司购买的C咖啡豆是最多的，所以，K的咖啡是最好的。

推理缺陷：买的咖啡豆多，并不能说明每单位成品咖啡里含的C咖啡豆多，所以也就不能说明该咖啡是最好的。

C：K公司出售的咖啡也是最多的。正好点明了该逻辑缺陷。
