C!
if the equipment is no different and the beans are better then it stands to reason that atleast these two items would not cause bad coffee and hence nothing in the question stem or answer is overlooked here!

C)

Once you read this argument's facts and its conclusion, you can pretty much know what the flaw is. By the way, I'd suggest that you read the question first and then read the argument.

Very easy. C is the correct variant.

AD sugests: the company buys more colombian bean - so the company`s coffe must be the best.
But the possible solution may be that it just sells more coffee.

That variant corresponds us ti take C.

Problem for 45-60 seconds max.

C for Sure.

What if Company is producing such a large number of cans tht theres only some miligram of coffee in each, in such a case the reasoning in the argument fails.

The reasoning of the argument in the advertisement is flawed because it overlooks the possibility that

-->irrelevant
(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
-->leave for now and look for others to eliminate
(D) Kreemo’s coffee is the most expensive blended coffee available today
-->irrelevant, we are looking at coffee blends and not pricing to determine quality
(E) the best unblended coffee is better than the best blended coffee
-->well yes, this could be true but does it have anything to do with our particular argument? We are talking about BLENDED coffee only

How to solve this kind of questions? Let me know how you workout on this question.

I burned 2:16 on this question and actually had to use POE again to come up with the right answer.

So this leaves me with B and C. B looks to strengthen the argument. If we break down C we say that even though Kreemo buys the most Colombian coffee than any of its competitors because it sells more coffee than does any other company the blend MAY be low per bag resulting in lower quality. This MAY is important.

KUDOS
I would provide may be the best explanation to this question.

let us say there are three companies A, B and Kreemo Coffee (KC).

Company:________________________ A | B | KC |
Columbian beans used in production:___1 | 2 | 20 |
Total beans used in production:_______10 |10 |1000| <- WHO PRODUCES/SELLS MORE?!
concentration (quality):_____________10%|20%| 2%| <- What is the best quality?

The higher the concentration the better the quality of coffe.

therefore C is the best answer, whihc is saying that although KC sells more it's quality isn't the best.

clean C.

assumption in conclusion. Hence flaw in conclusion.

C brings out the assumption that more coffee does not mean more blended coffee produced.

How to solve this kind of questions? Let me know how you workout on this question.

This question is flawed in my opinion, because none of the options really present a correlation between columbian beans and the coffee sold as cans.

If I had an options saying, "it overlooks the possibility that the coffee blend in the can may not even contain the purchased Columbian beans".

What's the guarantee that Kreemo’s Coffee is not reselling the columbian beans at a higher price and used some other bean for the coffee blend in the can the ad talks about. The other flaw is that there's no comparative analysis between the concentration of coffee beans used by Kreemo's and its competitors.

"C", in my opinion, could be a possible assumption but not a flaw. Kreemo's Coffee cans could be best even if they don't get sold as much as their competitor's. Where is it mentioned that quantity of sale determines the quality of a product. Maybe the company is not able to sell its coffee because of poor marketing. Thus, Kreemo's cofee could possibly be the best coffee inspite of not having a good sale.

KUDOS
Fluke,
I might agree with you to a certain extent.
the source is unknown (well, it is from 1000 series, but is it a seflmade question or it came from GMAT-paper tests, or any other source i don't know).

A good question does not require additional assumptions to arrive to correct answer choice.

The argument says:
premise 1: "the more Colombian beans in a blend of coffee, the better the blend".
It means that best blend is achieved when a coffee maker uses 100% of Columbian beans.

premise 2: "no company purchases more Colombian beans than Kreemo Coffee. Inc"

Conclusion "Kreemo’s coffee is best blended coffee " (this is why E is wrong).

So the K's coffee is best because they buy a lot of C beans.

To weaken a question one must weaken the conclusion. But, the correct answers do not have to absolutely, without a doubt, in all circumstances weaken the conclusion. They only have to open up the possibility that the conclusion is not valid. The correct answer on a weaken question will typically accomplish this by introducing a new piece of information that calls into question an assumption made by the author.

The possible assumptions made by author are:
1. KC does not resell Columbian beans,
2. KC uses all Columbian beans in production of coffee
3. None of competitors puts more Columbian beans in coffee than KC does.
4. Quantity of Columbian beans and the coffee sold as cans perfectly correlates.
5. beans are used in production of coffee.
6....etc

You are right saying that:
Quote:
it overlooks the possibility that the coffee blend in the can may not even contain the purchased Columbian beans

your statement attacks the 2nd assumption.

I definitively agree with this statement:
Quote:
" is not reselling the columbian beans at a higher price and used some other bean for the coffee blend"
it weakens the 1st assumption.

this is are both very valid weakening arguments, but in test-makers view these are too easy to spot.
Thus probably they decided to use the argument that weakens the 3rd assumption:
"C) Kreemo sells more coffee than does any other company "

but this answer is too stretched. Why?!

Because it requires additional assumptions, such as "all coffee beans that KC buys, it uses later in production", "purchases are equal to sales", "no columbian beans are stored in stock", etc...

But C opens up a possibility that high volumes does not necessarily mean high % or in our case higher quality.

In my example above you may change the figure 20 in 400 resulting in 40% instead of 2% concentration of Columbian beans in a cup of coffee. This strenghtens the argument.
But also the total volume of beans a company purchases leaves a gap in possibility to intrepret differently the given information.

If the argument said that KC sells less coffee than any other company and buys more columbian beans than any other company, it would be much difficult to weaken such argument. (becuase it would result in higher concentration of coffee beans).

Hope it helps.

Suppose,
Kreemo sells 100 pounds of coffee and uses 50 pounds of Colombian beans.
XYZ another company sells 20 pounds of coffee and uses 20 pounds of beans.
XYZ sells better quality blended coffee than Kreemo because it uses 100% Colombian beans.

I hope it is clear.

C can not be correct. Kreemo sells more coffee, so it might be using less good beans per can and it might just be selling more because it has a larger market share.

E is the correct answer, because it allows us to know that you might not have the best blended coffee although having the best columbian beans (the unblended).

I got the answer rather quickly but may have been lucky. When I read the prompt I immediately made the connection that purchasing more beans does not mean having more beans in the product you sell. The only answer choice that highlighted this discrepancy was answer C.

picked c but it was tricky.

if you sell a more coffee, you can lose the "prime best blend" ratio if that makes sense

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

According to most posts on here, this is supposedly a weaken question. However, the question askes to identify the flaw in the reasoning - which points to a FLAW question, an entirely different type of question.

KAPLAN BOOK: For Flaw questions, find the conclusion, evidence, and central assumption(s), then pre-phrase an answer that indicates the logical fallacy of the assumption

What is the central assumption? The central assumption is, that since Kreemo buys most of the Colombian coffee (which is the best) that it sells the highest quality blend.

A flaw question requires you to find the logical fallacy of the assumption.

(A) If the central assumption is that the amount of colombian coffee purchased is the only indicator for a high quality blend, it certainly includes the assumption that any kind of 'blending' would be indentical among competitors - which may not be the case. By considering that the 'blending' also impacts the quality, the argument becomes flawed.

(C) If the central assumption is that the amount of colombian coffee purchased is the only indicator for a high quality blend, the fact that Kreemo sells more coffee than its competitor has nothing to do with the amount of the blend in it - at least without massive mental fabrication of coffeebean ratios. Since Kreemo buys more Colombian coffee than anyone else, it is reasonable to assume that this fact alone is the cause.

Lets try this again, assuming this is a weaken question.

For Weaken questions, find the conclusion, evidence, and central assumption(s), then pre-phrase an answer that denies (weakens) a central assumption, then go to answer choices

The conclusion is that Kreemo makes the best coffee blend. The Evidence is that Kreemo buys more colombian coffee than any other competitor and the central assumption is that the coffee quality only relies on the amount of colombian coffee in the blend.

A similar logic than above can reasonably be applied.

If this is an official GMAC question and (C) is the official answer, I would like to hear what the fact that Kreemo sells more coffee than anybody else has to do with the central assumption - WITHOUT adding excessive fabrication and numerous additional assumptions about the quality of coffee that may or may not be thinned out or blended with other coffees.

Hey All,

Everybody seems to be on the right track with this one, but I wanted to respond to a few complaints. This is a VERY realistic GMAT question. There are no ambiguous answers. The problem is only if you spend too much time writing stories in your head, in which case, any answer choice can begin to look good. This argument says they buy the most Colombian beans, but think of it this way:

If I buy 10 beans and you only buy one bean, it may look like I must have the best coffee.

But if you only sell one cup of coffee, your one bean means the overall quality of your coffee is super excellent.
If I then sell 10,000 cups of coffee, splitting my ten beans between them, the overall quality of my coffee is super poor.

This is why the answer is what it is. Don't get into thought processes involving the history of the company, why people buy their coffee, what effect technology may have...ANYTHING that isn't in the passage itself. Keep in mind that this question asks you weaken THE ARGUMENT, not THE CONCLUSION, so you won't be bringing in any new information.

Word up.

Hope that helps!

Hi,

Hope we can discuss no matter what the correct answer is:
Conclusion Kreemo’s Coffee Buying the best blended coffee available today.

Consider this :

Kreemo's Sale : 10 M.....Near Competitor : 9 .5 M

Kreemo's no doubt selling more coffee than others , but this has no relation with buying and blended coffee.

Regards
Sanjiv
