flaw in reasoning

[gmatnmein2010]

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

Premise 1: The world's best coffee beans come from Colombia
Premise 2: The more Colombian beans in a blend of coffee, the better the blend, and no company purchases more Colombian beans than Kreemo Coffee, Inc.
Conclusion: 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 sentence need an assumption : Kreemo's sales figure must be comparable that of others if the quality will be compared. If Kreemo sells more coffee than others than it is incorrect to assert that their coffee is best since The more Colombian beans in a blend of coffee, the better the blend,

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
Incorrect : New information (equipment) is introduced here. Ruled out.

(B) not all of Kreemo's competitors use Colombian coffee beans in the blends of coffee they sell
Incorrect : What competitors do and not do is not the issue here. Checked out.

(C) Kreemo sells more coffee than does any other company
Correct : This is the unwarranted assumption that the author makes in the argument above. Just because kreemo purchases more colombian beans does not mean that every can they sell has more colombian coffee beans. It could be that kreemo sells more coffee than does any other company and therefore purchase more colombian blend.

(D) Kreemo's coffee is the most expensive blended coffee available today
Incorrect : Price is not the issue here. Quality is the issue here.

(E) the best unblended coffee is better than the best blended coffee
Incorrect : The stimulus above focuses exclusively on blended coffee.

Hope this helps : )
