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

OA is C, but why? I chose E

Question is from GMAT disclosed test No31

hi capnx,

i think E is out of scope because the argument only talks about the best blended coffee. Unblended coffee is out of scope.

C is the flaw, coz, the fact that Kreemo sells more coffee than any other company is probably the reason, it purchases more coffee than any others.

hi kiennguyen
break the argument to see the conclusion and the supporting premises.

conclusion of the argument:
if you buy a can of Kreemo's coffee, you're buying the best blended coffee available today

Premises
(1) The world's best coffee beans come from Colombia.

(2) The more Colombian beans in a blend of coffee, the
better the blend

(3) no company purchases more Colombian beans than Kreemo Coffee, Inc.

therefore the argument has an inherent assumption that because kreemo purchases more coffee than any other company, the cans it makes have a higher blend of Columbian beens.
However,if Kreemo sells more coffee than any other company, then it manufacturers more coffee than any other company. Hence the extra Columbian beens don't increase the blend of individual cans of Coffee, but they increase the Number of Cans, which is what is stated in C.
i hope i made myself clear.

appreciate your kindness! i got it now!

it is very true that if "Kreemo sells more coffee than does any other company", the proportion of Columbia coffee in a single can which it sells may not be higher than that of other companies.

But gmatmachoman, vineet and kiennguyen's interchange was excellent.

Let me know if there is something specific bothering you here.
