### HideShow timer Statistics

Modern navigation systems, which are found in most of todayâ€™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

This is the kind of questions that I'd be confused. Could somebody explain a little bit about what the following terms mean: Argument, principle, position, consideration, and conclusion, and what are the relationships among them? I would greatly appreciated!

My attempt:

Modern navigation systems, which are found in most of todayâ€™s commercial aircraft, are made with low-power circuitry, which is more susceptible to interference than the vacuum-tube circuitry found in older planes. (Position)
During landing, navigation systems receive radio signals from the airport to guide the plane to the runway. (Fact)
Recently, one plane with low-power circuitry veered off course during landing, its dials dimming, when a passenger turned on a laptop computer. (Evidence)
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)

On basis of this, I would say that (B) is correct.

Hong Did you notice the must in choice B?

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

Do you still want to stick with B?

E.

I think the must in B is too emphatic. In A the conclusion is drawn from the first is a bit off a stretch.

E conveys the sense of plausibility based on the facts given in the argument.

Well, choose bt B and E, I'd still choose B, since the first sentence can't be a principle?

You have a point, perhaps the first is not a principle, but I dont like B. D is a better choice than B imo.

I like "E".....first is not a fact or a number it is a fundamental priniciple that can't be argued. That leaves us with A and E. However, 2nd statement can't be drawn from first, hence A is out.

Explain!

B/W B and E. I go with B

in E, why the first sentence is necessary? I don't think so.

On a second thought.

I go with E.

It seems very risky that passengers' electronic device will interfere with the communication between the plane and the airport during the landing.

So, first boldface is necessary.

B, the word must of the second boldface is a little confusing.

Quote Paul's article

Principle: something fundamental that we do not question. This would be somewhat stronger than a fact because it is not specific to a limited number of cases but instead, apply to a broader range of scenarios(and often deeper in meaning). For instance, you will not talk about the principle that crime is increasing in large cities. Instead, it is a fact which applies to large cities. However, you will talk about the principles of Physics or the fundamental principles of Human Rights. I believe principles convey a stronger connotation than mere facts.

Fact: something taken as true at face value (stats, historical events)

(B)
I just finished reading PAUL's explanation of principle, facts, inference, assumption etc. And according to that thread, a principle is stronger than a fact so in this case, the fisrt part in boldface [b]"During landing, navigation systems receive radio signals from the airport to guide the plane to the runway. "[/b is more of a fact than a principle because i don't think it applies everywhere. It only applies in this scenario. Someone correct me if i am wrong

I don't have the OA with me for this one. In one of the other threads the OA for this is mentioned as B) http://www.gmatclub.com/phpbb/viewtopic ... ght=#28240

I elect B. The first statement is an (alleged) factual assertion. Must is a bit strong but I still prefer this answer to E.

the OA is C

I initial pick was E, guess E and B both are too strong to be the right answre.

Can someone explain what is "consideration", what's the difference between "consideration" and "premise"?
