GMAT Critical Reasoning Discussions

My Choice is D .

Reason : Assumed that initiative will eradicate the prevailing issue . Also , it is something going with the long term thinking of the government .

Hi JM ,

I do agree the reason you have putforth .

That the policy of nuclear deterrence has worked thus far is unquestionable. Since the end of the Second World War, the very fact that there were nuclear armaments in existence has kept major powers from using nuclear weapons, for fear of starting a worldwide nuclear exchange that would make the land of the power initiating it uninhabitable. The proof is that a third world war between superpowers has not happened.Which one of the following, if true, indicates a flaw in the argument?
A. Maintaining a high level of nuclear armaments represents a significant drain on a country's economy.
B. From what has happened in the past, it is impossible to infer with certainty what will happen in the future, so an accident could still trigger a third world war between superpowers.
C. Continuing to produce nuclear weapons beyond the minimum needed for deterrence increases the likelihood of a nuclear accident.
D. The major powers have engaged in many smaller-scale military operations since the end of the Second World War, while refraining from a nuclear confrontation.
E. It cannot be known whether it was nuclear deterrence that worked, or some other factor, such as a recognition of the economic value of remaining at peace.

Premise: No third world war
Conclusion: nuclear deterrence has worked
To find flaw in the argument, we need to find some reason other than nuclear deterrence which might have prevented war.

A. Not relevant
B. Talks about future, Not relevant
C. 'nuclear accident', Not relevant
D. smaller-scale military operations doesnt affect conclusion
E. Find another reason, economic value, of no war

IMO: E

IMHO:E
A:Out of scope.
B:Talks about future.
C.Same premise.
D.Involves small scale operations.
E.Cites another reason for the effect which undermines the validity of the argument.

The spacing of the four holes on a fragment of a bone flute excavated at a Neanderthal campsite is just what is required to play the third through sixth notes of the diatonic scalethe seven-note musical scale used in much of Western music since the Renaissance. Musicologists therefore hypothesize that the diatonic musical scale was developed and used thousands of years before it was adopted by Western musicians.Which of the following, if true, most strongly supports the hypothesis?
(A) Bone flutes were probably the only musical instrument made by Neanderthals.
(B) No musical instrument that is known to have used a diatomic scale is of an earlier date than the flute found at the Neanderthal campsite.
(C) The flute was made from a cave-bear bone and the campsite at which the flute fragment was excavated was in a cave that also contained skeletal remains of cave bears.
(D) Flutes are the simplest wind instrument that can be constructed to allow playing a diatonic scale.
(E) The cave-bear leg bone used to make the Neanderthal flute would have been long enough to make a flute capable of playing a complete diatonic scale

OA is :

Frobisher, a sixteenth-century English explorer, had soil samples from Canada's Kodlunarn Island examined for gold content. Because high gold content was reported, Elizabeth I funded two mining expeditions. Neither expedition found any gold there. Modern analysis of the island's soil indicates a very low gold content. Thus the methods used to determine the gold content of Frobisher's samples must have been inaccurate.

Which of the following is an assumption on which the argument depends?

(A) The gold content of the soil on Kodlunarn Island is much lower today than it was in the sixteenth century.

(B) The two mining expeditions funded by Elizabeth I did not mine the same part of Kodlunarn Island.

(C) The methods used to assess gold content of the soil samples provided by Frobisher were different from those generally used in the sixteenth century.

(D) Frobisher did not have soil samples from any other Canadian island examined for gold content.

(E) Gold was not added to the soil samples collected by Frobisher before the samples were examined.

Premise: The spacing of the four holes on a fragment of a bone flute plays the third through sixth notes of the diatonic scale
Conclusion: The WHOLE diatonic scale was known

It uses the premise of 3-6th notes and says 1-7the notes are known. We need to choose an answer which fills this gap.

(A) Even if Neanderthals made other instruments as well doesn't change anything.
(B) Even if diatonic was known earlier than Neanderthals doesn't matter because it should just be known before western civilization.
(C) Not relevant
(D) Not relevant
(E) If cave-bear leg bone is not enough to make whole flute than all notes cannot be on the flute hence argument falls apart.

IMO: E

(E) Gold was not added to the soil samples collected by Frobisher before the samples were examined.


Premise: Previous sample more gold content prediction.
Latest sample less gold content prediction.
Conclusion: Previous method was faulty.

Which should look at an assumption where gold was not added/removed from the sample so as to make sure the observations are correct.

A. Economy was never in the scope of the argument
B. Irrelevant to the argument
C. Nuclear accidents are not in the scope of the argument
D. Gives an alternative reason to say that the third world war could still take place. Therefore my answer
E. Though, this option does look like a possible answer, I feel it is ambiguous. Therefore did not choose it.

IMO: D

(E) Gold was not added to the soil samples collected by Frobisher before the samples were examined.


Answer should be E , since they assumed the methods were incorrect rather than manipulation of the sample itself which was the other possibility

Its again option E... in the option itself it contradicts the premise and shows that there is a flaw in the argument πŸ˜ƒ

I think its C

My take is E.

This one is frm the OG10. Please post the complete solution for this

Thanks...

High levels of fertilizer and pesticides, needed when farmers try to produce high yield of the same crop year
after year, pollute water supplies. Experts therefore urge farmers to diversify their crops and to rotate their
plantings yearly.
To receive governmental price-support benefits for a crop, farmers must have produced that same crop for the
past several years.
The statements above, if true, best support which of the following conclusions?

(A) The rules for governmental support of farm prices work against efforts to reduce water pollution.

(B) The only solution to the problem of water pollution from fertilizers and pesticides is to take farmland out of
production.

(C) Farmers can continue to make a profit by rotating diverse crops, thus reducing costs for chemicals, but not by planting the same crop each year.

(D) New farming techniques will be developed to make it possible for farmers to reduce the application of fertilizers and pesticides.

(E) Governmental price supports for farm products are set at levels that are not high enough to allow farmers to get out of debt.

Bhai I feel it shud be Option A.

Not B : One cannot conclude it's the only solution
Not C : Nowhere it is mentioned that farmers can't make profit by planting the same crop each year.
Not D : "new farming techniques" ??? kaahaan yaar???
Not E : Who said that ?
