Since we did not see too many CR's discussed here lately, we decide to start this challenge series in CR too. I do not rule out a SC series in the next future. you will only do yourself a favor by following the rules. Doing practice under a timed environment will only help you. good luck. if you write down how you got your answer, you can compare others strategies and it will benefit each other.

Go guys!

Rules
1. Time yourself
2. Solve this seperately.The correct and fastest solution wins
3. After you have reached your answer, explain your solution clearly, and write down your times. if you dont want to be specific, please write down: <2min or >2 min

The worldтАЩs 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
KreemoтАЩs coffee, youтАЩre 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 KreemoтАЩs competitors use Colombian
coffee beans in the blends of coffee they sell
(C) Kreemo sells more coffee than does any other
company
(D) KreemoтАЩs coffee is the most expensive blended
coffee available today
(E) the best unblended coffee is better than the best
blended coffee

I thought it was E,,almost 2 mins...But my main weakness is CR...so I might be wrong.....
A and B are not related that much to the central theme of the argument...
Being most expensive or selling most doesnot seem to be a flaw in the reasoning...SO we are left with E.....
Like i told you before..my reasoning might be wrong....

C for me
If Kreemo sells more coffee than any other company, then it is not a guarantee that you will get the best coffee because they buy more Columbian coffee. Let's have a number example.
Kreemo sells 10 pounds of blended coffee
Kreemo buys 5 pounds of Columbian coffee
Probability of getting "best coffee" is 5/10 = 50%
Competitor sells 2 pounds of blended coffee
Competitor buys 2 pounds of Columbian coffee
Probability of getting "best coffee" is 2/2 = 100%
We can see that Kreemo DOES indeed buy more coffee in the above example. However, we cannot conclude that based ONLY on the amount of coffee Kreemo buys, it is a GUARANTEE that we will get "the best" blended coffee around. For the us to conclude about the guarantee, we would also need to know if it sells as much coffee than it buys Columbian beans
About 2 min.

I vote for "A". "A" immediately points out the flaw in reasoning. In spite, Kreemo purchases colombian beans but if machine to blend and package coffee is the same as other rivals, coffee can never be of superior quality.

Dharmin, your conclusion relies on one crucial assumption: The quality of blended coffee hinges only on the quality of the coffee blending and coffee packaging equipment. However, there is nowhere mention of your assumption in the excerpt.

Paul, actually i considered the fact that coffee blending and packaging machine requires one pool of coffee beans and another one of water (or the another ingredient requires to prepare coffee)
Now, if the making of such equipment is of same brand the equipment mixes same amount of ingredents.

whats say, paul ?

Nice try , guys . C is indeed the best answer :)

Ok..I am again quoting here.

A couple of tips for people...

- Make sure you know the conclusion first before reading the answer choices. In this case the conclusion is if you buy a can of Kreemo, you're buying the best blended coffee today.

- Take the evidence as *fact*. More Colombian beans in a blend equals better blended coffee. Kreemo also buys the most Colombian beans. These statements are irrefutable and must always be true in the argument.

- Next, determine what is missing between the evidence and the conclusion? These are the assumptions that are made to connect the evidence with the conclusion. Paraphrase possible answers by refuting these assumptions before you read the choices. The obvious one is if Kreemo sells so much coffee that the amount of Colombian beans used per cup is lower than some other company's coffee. This does not violate either pieces of evidence, but definitely calls the conclusion into question.

- Remember, you're trying to refute the conclusion, not the evidence. Stay focused on the scope of the conclusion.


Good enough?
