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 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

looks lijke question from 1000 cr

i went with E because the first one is the principle whi ch could be understood and the second is the conclusion which is explicitly led by conclusion indicator

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.

Hope this help

Thanks Carcass.
Just went through MGMAT and learnt that
"evidence", "circumstance", "finding" are synonymous to "fact" - per GMAT - CR terms.
Any claim made by the author is "opinion"

This will help in not finding the right answers but eliminating the wrong ones.

Also to add, i have seen answer choices having words like consideration, support, drawn, etc..

So how to find out the appropriate answer choices from these distinctions?

for me is the wrong strategy what you are trying to follow.

I mean is important to understand what's going on, the situation the context and EVEN the single words as indicator.

(C) The first acknowledges a consideration that supports that main position; the second is that conclusion. - Correct because the first one supports the main position.
(D) The first is an evidence that supports the conclusion, the second is that conclusion. - The first is not the evidence, it's one of the supporting statements to the main position.
(E) The first is a principle that is necessary for this argument, the second is a conclusion that could be drawn from this argument. - Same error as D

Hi mbaiseasy,

As you said if the statement is removed. How will we know with what waves the radio signals from the laptops or other instruments interfere with???

Please correct me if i am wrong.

In case such questions show up in the real test you need to have already saved extra time from other simple question to be able to tackle these hard questions

The option B is wrong because the argument does not rely upon the statement "During landing, navigation systems receive radio signals from the airport to guide the plane to the runway." It is indeed a supporting statement,i.e. fact, but you must test whether the argument collapses after the sentence is removed. As explained in several responses above, the argument stands even with the statement removed -- "it's dials dimming" has no connection to the radio signals altogether.

The trick is to understand the difference between background information and premises.
I hope this helps.

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

So these kinds of questions falls under the category IF 'X', then Y is the conclusion and vice versa, am I right?

I opted for B.
However OA is C.In the explanation of B,it is told that the argument does not rely on this fact.I cannot understand this.
"navigation systems receive radio signals from the airport to guide the plane to the runway" on this very statement argument relies.If any interference is done in any form(laptop etc) during landing,aircraft is put at risk.
