Modern navigation systems are made with low-power circuitry, which is more susceptible to interference than the vacuum-tube circuitry found in older planes. ................................more weak
During landing, navigation systems receive radio signals from the airport to guide the plane to the runway...............general fact or principle
Recently, one plane with low-power circuitry veered off course during landing when a passenger turned on a laptop computer............one example of weakness mentioned above
Clearly, modern aircraft navigation systems are being put at risk by the electronic devices that passengers carry on board, such as cassette players and laptop computers.............................conclusion of the argument

The two portions in boldface play which of the following roles?

(A) The first is a principle that the argument relies on and the second is a conclusion that can be drawn from the first.
The first is a principle that the argument relies on because if it is negated then conlusion cannot be drawn from the example.
and second is a conclusion but it cannot be drawn from the first.


(B) The first is a fact that argument relies on and the second is a conclusion that must be drawn from this argument.
The first is true as above.
second is a conclusion but it need not be must be drawn from this argument.

(C) The first acknowledges a consideration that supports that main position; the second is that conclusion.
The first does not acknowledge a consideration and neither it supports the main position. Second is not that conclusion.

(D) The first is an evidence that supports the conclusion, the second is that conclusion.
no true becase of same reasons as in C.

(E) The first is a principle that is necessary for this argument, the second is a conclusion that could be drawn from this argument.
The first is necessary as counter example and conclusion rely on it and second is a conclusion that can be drawn from the argument.

Could you please explain what is meant or what makes up "the main position" in answer (C)? How it is different from the conclusion in this question?

(C) The first acknowledges a consideration that supports that main position; the second is that conclusion.

Shouldn't the OA change to E based on the explanations on this thread? Else, can someone please explain how is 'C' correct? Thanks a lot!

Hi souvik101990,

Could you please confirm whether the OA marked is correct?

I think answer should be E, as well explained by Nevernevergiveup.

My 2 cents:
I too think E should be the answer because of the 2nd part - The second bold statement is NOT a conclusion we can directly reach. There is a leap - NOT all cassette players and laptop computers interfere with the navigation system to the extent that it can impact low-powered circuitry. There may have been an electrical malfunction which caused the impact. So please check the answer.
Thanks

B,C, D, E all are lucrative.... Eliminated E because it is too strong (I don't know whether the principle is necessary)... Also eliminated D because the the 1st statement does not directly support the conclusion.... Now between B and C.... Can anyone please explain why C is better than B?

Hi souvik101990,

There is a lot of confusion over OA. B and E seems to be highly plausible, but alas, OA is none of the two. Please provide and explanation for the OA.

It seems the OA is debatable. Would you please explain why option E is incorrect?

Modern navigation systems, which are found in most of today’s commercial aircraft, are made with low-power circuitry, which is more susceptible to interference than the vacuum-tube circuitry found in older planes. During landing, navigation systems receive radio signals from the airport to guide the plane to the runway. Recently, one plane with low-power circuitry veered off course during landing, its dials dimming, when a passenger turned on a laptop computer. Clearly, modern aircraft navigation systems are being put at risk by the electronic devices that passengers carry on board, such as cassette players and laptop computers.

The two portions in boldface play which of the following roles?

(A) The first is a principle that the argument relies on and the second is a conclusion that can be drawn from the first.

(B) The first is a fact that argument relies on and the second is a conclusion that must be drawn from this argument.

(C) The first acknowledges a consideration that supports that main position; the second is that conclusion.

(D) The first is an evidence that supports the conclusion, the second is that conclusion.

(E) The first is a principle that is necessary for this argument, the second is a conclusion that could be drawn from this argument.

I must acknowledge that I was tempted by option E, however, on further review, I see why option C is better. For BF1, it is not clear which argument is referred to in option E, therefore while it seems right as it connects well with BF2 (main conclusion), it is not.

Option C, on the other hand, is clear and concise in saying BF1 is a consideration (i.e reasoning/assumption) which supports the main argument (BF2).

I think the lesson learned in this BF CR, is to stop finding excuses to make an option correct. If it's is not clear and you have been diligent in deconstructing the prompt, then the option is simply wrong. Be confident in your judgment and eliminate, however tempting the muddled option is. Often the correct answers in BF CRs are concise, global and direct.

I have been trying to understand ways to crack the bold face CRs, but i am finding it tough on various fronts.

1. Couldn't distinguish between words like principle/fact/evidence.. acknowledge/asertain/supports. These are hairline differences and completely puzzled on how to solve this.
2. Couldn't figure out any way to systematically break down the stimulus(except the premise/conclusion) and figure out the right answer choices.

I need some materials or pointers towards that would be great(like page nos. of certain books/links etc) or ways/methods anything that would be helpful to understand how to solve bold faced CR questions besides brute dumb luck



Hi guy this is tough I admit. the gmat tries to blow you but you have to keep calm and break the problem into chunks.

This strategy is from MGMAT CR guide and it works.

So, here we are: first of all try to spot the conclusion in the argument ALWAYS. Now, our second bold statement coincides with the conclusion or main idea of the argument, so you can label it as C.

The first bold part can be: in favour of the conclusion so you can label it as P (premise that support the author conclusion) or X (a statement that is something else: for instance an example a fact and so on).

So here we have a X C combination because the X is something that support conclusion INDIRECTLY in this case and the second bold part is our CONCLUSION. In our answer choices we have to figure out this combo

Now, here simple part of our work:

A and E are suddenly out because our X is not a principle.

B the first is not something on the argument rely on because the opening of a laptop is the problem reason during the land

D here we have a evidence or aka PREMISE but we have a X not a P, and also he does not support directly the author conclusion but indirectly

C The first acknowledges a consideration that supports that main position; the second is that conclusion.

Perfect. We have an X C combo.

Answer should be C. Please provide OA.

Hope this help :)







Hi Carcass,

Could you please define Consideration and Principle.
