In the argument given, the two portions in boldface play which of the following roles?

(A) The first supplies a context for the argument; the second is the argument's main conclusion.
(B) The first introduces a development that the argument predicts will have a certain outcome; the second is a state of affairs that the argument denies will be part of that outcome.
(C) The first presents a development that the argument predicts will have a certain outcome; the second acknowledges a consideration that weighs againstthat prediction.
(D) The first provides a certain outcome that the agrument seeks to weigh against; the second is a consideration that support the main conclusion.
(E) The first and the second each provide evidence to support the argument's main conclusion.


Responding to a pm:

What is the essence of the argument?
Genetically modified seeds are highly resistant to insects. But they are more expensive and need more fertilizer and water. So farmers won't save money by using them (prediction).
But people like them so their use will keep increasing (conclusion).

So what part is in bold? Let me underline it to show clearly...

Wrong - second is not the main conclusion

(B) The first introduces a development that the argument predicts will have a certain outcome; the second is a state of affairs that the argument denies will be part of that outcome.
Wrong - the second is not related to the outcome at all. It cannot accept or deny whether it is a part of that outcome

(C) The first presents a development that the argument predicts will have a certain outcome; the second acknowledges a consideration that weighs against that prediction.
Wrong - second is not a consideration against the prediction. Prediction is about saving money by using modified seeds. Just because people like modified seeds, farmers won't save money by using them i.e. the cost will not go down. Note that the revenue farmers earn may increase because people like these seeds but the cost of using them will not decrease.

(D) The first provides a certain outcome that the agrument seeks to weigh against; the second is a consideration that support the main conclusion.
Correct.

(E) The first and the second each provide evidence to support the argument's main conclusion.
Wrong - First does not provide evidence to support conclusion

Your first bold is different than this one. your answer is correct if first sentence is bold because its that development of seeds. But in this question D is correct.

Hi VeritasPrepKarishma, can you please help me understand how agrument is seeking to weigh against First bold face sentence.
It looks like, from the argument, the author is acknowledging the fact in first bold face and providing an alternative explanation for why the plan may work.

Counter Conclusion :- Unfortunately, the seeds themselves are quite expensive, and the plants require more fertilizer and water to grow well than normal ones.
Counter premise :- Thus, for most farmers the savings on pesticides would not compensate for the higher seed costs and the cost of additional fertilizer.

Conclusion :- However,since consumer demand for grains, fruits, and vegetables grown without the use of pesticides continues to rise, the use of genetically engineered seeds of this kind is likely to become widespread

Required is Counter + Support for conclusion

IMO :- D

try to diagram the argument, numbering each of the sentences and using the 'THEREFORE TEST' (try 'x, therefore y' and 'y, therefore x', and see which, if either, of them makes sense).

1 Plant scientists have used genetic engineering on seeds to produce crop plants that are highly resistant to insect damage.
2 Unfortunately, the seeds themselves are quite expensive, and the plants require more fertilizer and water to grow well than normal ones.
3 Thus, for most farmers the savings on pesticides would not compensate for the higher seed costs and the cost of additional fertilizer.
4 However, since consumer demand for grains, fruits, and vegetables grown without the use of pesticides continues to rise, the use of genetically engineered seeds of this kind is likely to become widespread.

the structure of this argument is:
1 = background fact
2, therefore 3
however, 4 (which weakens conclusion 3)

if you figure out that much, then it's clear that #3 is the CONCLUSION. (that's the single most important thing you can do on critical reasoning: figure out what's the conclusion.)

since neither of the boldface portions is the conclusion, choice a and choice d are dead. (both of those claim that the second part is the conclusion.)

now, analyze the boldface parts a little better:
#2 (the first boldface) serves as a premise for #3
#4 (the second bold) serves as a counterpoint to #3, weakening the lasting value of the conclusion
...which is basically what choice c says.

choice b is tempting, but you should note that the argument is specifically designed to point out that this 'state of affairs' CAN affect the outcome. choice e is nonsensical, as the two boldfaces are on completely opposite sides of the proverbial fence.

(Background information) Plant scientists have used genetic engineering on seeds to produce crop plants that are highly resistant to insect damage. (Counter premise) Unfortunately, the seeds themselves are quite expensive, and the plants require more fertilizer and water to grow well than normal ones. (Counter-conclusion) Thus, for most farmers the savings on pesticides would not compensate for the higher seed costs and the cost of additional fertilizer. (Premise - "However," changes direction of argument, everything prior to this statement is now the Counter argument) However,since consumer demand for grains, fruits, and vegetables grown without the use of pesticides continues to rise, (Main Conclusion) the use of genetically engineered seeds of this kind is likely to become widespread.

**After identifying paragraph structure, should be able to move quickly through answer choices - moving wrong to right**

In the argument given, the two portions in boldface play which of the following roles?

(A) The first supplies a context for the argument,; the second is the argument's main conclusion. - The first sentence is background info, not the first bold. eliminate
(B) The first introduces a development that the argument predicts will have a certain outcome; the second is a state of affairs that the argument denies will be part of that outcome. - Huh? Leave in for now
(C) The first presents a development that the argument predicts will have a certain outcome; the second acknowledges a consideration that weighs against that prediction. - For argument; Against argument <-- Nope. We've already determined the first bold is a counter-premise and second is supporting main conclusion.
(D) The first provides a certain outcome that the agrument seeks to weigh against; the second is a consideration that support the main conclusion. - Counter-premise; Premise to the main conclusion
(E) The first and the second each provide evidence to support the argument's main conclusion. - Nope. We've already determined the first bold is a counter-premise.

Another bad CR question. People are saying the second half of C is wrong, when the first half of D is even more wrong.

" the seeds themselves are quite expensive, and the plants require more fertilizer and water to grow well than normal ones" is not an outcome... The sentence after that is the outcome. I can see why C is wrong, but D is also wrong. Maybe the test makers fell asleep on this question.

It is an outcome of "Plant scientists have used genetic engineering on seeds to produce crop plants that are highly resistant to insect damage."
They have created seeds that are resistant to insect damage. The outcome of modifying the seeds is that these modified seeds are expensive and need more fertilizer and water.

You cannot brush aside official questions as bad questions. Try to understand what is going on. You could get something very similar on your test too.

"However" is used to "weigh against", and the main conclusion is "seeds will become widespread". Is it how it works?


Unfortunately,
Premise 1. the seeds themselves are quite expensive, and the plants require more fertilizer and water to grow well than normal ones.
Sub-conclusion: Thus, for most farmers the savings on pesticides would not compensate for the higher seed costs and the cost of additional fertilizer.

The first provides a certain outcome that the agrument seeks to weigh against;

However (weigh against)

Counter-argument and Premise 2: since consumer demand for grains, fruits, and vegetables grown without the use of pesticides continues to rise,

Main conclusion: the use of genetically engineered seeds of this kind is likely to become widespread.

The second is a consideration that support the main conclusion.

I'm not brushing it aside. You are making the assumption the test makers' questions are foolproof - that is not the case. You replied saying the outcome is that the seeds are expensive which is what I'm trying to say. The bold portion itself IS NOT an outcome. An outcome is a consequence, the bold portion in by no means is a consequence, result or causation. Furthermore, answer D says it is "an outcome the argument seeks to weigh against". The argument isn't weight against "the seeds themselves are quite expensive, and the plants require more fertilizer and water to grow well than normal ones" its weighing against the sentence AFTER the bold portion. It's just plain wrong.

D is the correct answer.

Plant scientists have used genetic engineering on seeds to produce crop plants that are highly resistant to insect damage - General Information
Unfortunately, the seeds themselves are quite expensive, and the plants require more fertilizer and water to grow well than normal ones - Premise by the author
Thus, for most farmers the savings on pesticides would not compensate for the higher seed costs and the cost of additional fertilizer - Intermediate conclusion by author
However,since consumer demand for grains, fruits, and vegetables grown without the use of pesticides continues to rise - Premise by author
the use of genetically engineered seeds of this kind is likely to become widespread- Main conclusion by athor

Fist BF statement is a premise that provide a conclusion - savings would be less. So, if BF is applicable, a consequence or an outcome happens in result. Second BF is a prediction by author. And it supports main conclusion

It's clearly between C & D.

I think the problem with C is that it states the first Boldface is a "development".

How is the statement "Unfortunately, the seeds themselves are quite expensive, and the plants require more fertilizer and water to grow well than normal ones" a development? It is more like a fact, to me.

I refuted C, based on that, and went for D.

Responding to a pm:

What is the essence of the argument?
Genetically modified seeds are highly resistant to insects. But they are more expensive and need more fertilizer and water. So farmers won't save money by using them (prediction).
But people like them so their use will keep increasing (conclusion).

So what part is in bold? Let me underline it to show clearly...

Genetically modified seeds are highly resistant to insects. But they are more expensive and need more fertilizer and water. So farmers won't save money by using them (prediction).
But people like them so [i]their use will keep increasing (conclusion)

(A) The first supplies a context for the argument; the second is the argument's main conclusion.
Wrong - second is not the main conclusion

(B) The first introduces a development that the argument predicts will have a certain outcome; the second is a state of affairs that the argument denies will be part of that outcome.
Wrong - the second is not related to the outcome at all. It cannot accept or deny whether it is a part of that outcome

(C) The first presents a development that the argument predicts will have a certain outcome; the second acknowledges a consideration that weighs against that prediction.
Wrong - second is not a consideration against the prediction. Prediction is about saving money by using modified seeds. Just because people like modified seeds, farmers won't save money by using them i.e. the cost will not go down. Note that the revenue farmers earn may increase because people like these seeds but the cost of using them will not decrease.

(D) The first provides a certain outcome that the agrument seeks to weigh against; the second is a consideration that support the main conclusion.
Correct.

(E) The first and the second each provide evidence to support the argument's main conclusion.
Wrong - First does not provide evidence to support conclusion


Responding to a pm:

Hi there,

What do you think about the explanation provided by Manhattan Prep?

https://www.manhattanprep.com/gmat/foru ... t2270.html

The answer choices are slightly different, but that doesn't seem to have an impact on the reasoning (basically, they say it's C and you say it's not C).

The answer choice I selected was D however, the wording is not the same as the one on this page/discussion.
My option D states: The first provides evidence to support a prediction that the argument seeks to defend; the second is that prediction.
Option C appears to be consistent on all three pages (this page, Manhattan and mine).

Boldface questions are my weakest in Verbal and I am still torn between D and C.


The conclusion of the argument is the author's opinion. It is the reason he writes the argument. I disagree with the explanation provided in the link above. The conclusion of this argument is "their use will keep increasing" - that is the final word of the author. He starts by giving the drawbacks but provides a reason which he believes will overshadow the drawbacks and arrives at the conclusion that the use of genetically modified seeds will keep increasing.

"Thus, for most farmers the savings on pesticides would not compensate for the higher seed costs and the cost of additional fertilizer." is a prediction based on the drawbacks he discusses, not the conclusion of the argument.

(C) is wrong as discussed above.
(C) The first presents a development that the argument predicts will have a certain outcome; the second acknowledges a consideration that weighs against that prediction.
Wrong - second is not a consideration against the prediction. Prediction is about saving money by using modified seeds. Just because people like modified seeds, farmers won't save money by using them i.e. the cost will not go down. Note that the revenue farmers earn may increase because people like these seeds but the cost of using them will not decrease.

(D) is correct
(D) The first provides a certain outcome that the agrument seeks to weigh against; the second is a consideration that support the main conclusion.

The argument says "their use will keep increasing". The argument weighs against the drawbacks in the first three lines.
The second bold face supports the main conclusion.
