The country of Baurisia has, until now, been self-sufficient in both grain and meat. However, with growing prosperity in Baurisia has come a steadily increasing per capita consumption of meat, and it takes several pounds of grain to produce one pound of meat. Therefore, since per capita income in Baurisia is almost certain to rise further but increases in domestic grain production are highly unlikely, Baurisia is soon to become an importer of grain.

Which of the following, if true, most seriously weakens the argument?

(A) When people increase their consumption of meat, they also tend to increase their consumption of grain.

(B) The per capita consumption of meat in Baurisia is roughly the same accross all income levels.

(C) Per capita consumption of meat has not increased substantially in recent years in those countries from which Baurisia is likely to import meat.

(D) It is more economical for Baurisians to import meat than grain.

(E) During Baurisia's years of growing prosperity, the country's population has remained relatively stable.

I think I can understand that the reason behind the answer being D is based on this part of stimulus: "and it takes several pounds of grain to produce one pound of meat." But this statement seems to give only the comparative measure of meat and grain, not necessarily imply that several pounds of grain can be substituted by meat. Can someone please explain?

Hi :)

Welcome to the Club!

Look you have to dismantle this argument to premises and conclusion:

Premises:
- before meat and grain were enough
- per capita income will rise.
- as a result growing prosperity in Baurisia per capita consumption of meat will increase
- and by the way: (it takes several pounds of grain to produce one pound of meat)

Conclusion:
- they will import grain.


Now you must think about it in this way:
if import grain -> feed animals-> kill them->make meat-> meat to Baurisians
if import meat -> meat to Baurisians

In second chain you eliminate the the unnecessary chain "feed animals-> kill them->make meat->" wich is less economical way of producing meat.

Now, just take off the detail in blue, you will see that grain is irrrelevant here. The argument will look like "they had enough meat, but soon because their income increases they will need more meat" So why to buy grain if they need meat indeed?

:)

Aha I see now. So grain was a distraction. However, in that case the problem becomes too simple to be a question.

I though of the chain "if import grain -> feed animals-> kill them->make meat-> meat to Baurisians" that you presented, but I know that animals eat grass not grain. Therefore I dismissed that reasoning. But in the end the whole grain story is artificially thrust upon the basic argument about meat self sufficiency. Thanks for clarification, appreciate it.

You are welcome: )

I would say that grain or grass is less relevant here.

What is wrong with Answer Choice C?
I think the answer weakens the question in the way that it leaves out the possibility that the country can import meat directly from other countries.

I initially fell for (B) but then I realized it was already mentioned in the question, so (D) was then the only viable answer.

Hi,
Can you please clarify why B is not the answer


(B) "The per capita consumption of meat in Baurisia is roughly the same accross all income levels."

As you can see, this answer choice just gives you a break-down of the consumption accross income levels; which serves as a classic shell-answer. In the question itself, it is clearly stated that "with growing prosperity in Baurisia has come a steadily increasing per capita consumption of meat", so even if the consumption is the same accross all levels, in total, it is increasing.

Thus, B does not directly attack the conclusion of the arguement, which is the act of importing grain.

Conclusion:Baurisia is soon to become an importer of grain.

Reasoning: The correct answer weakens the conclusion that Baurisia will be an importer of grain. The incorrect answer supports or is neutral to the conclusion that Baurisia will be an importer of grain.

A) When people increase their consumption of meat, they also tend to increase their consumption of grain. Wrong - if meat and grain is consumed more, then grain imports are likely. Thus, the conclusion is supported.

B) The per capita consumption of meat in Baurisia is roughly the same accross all income levels. Wrong - Neutral. Even if consumption of meat is the same, the statement neither strengthens nor weakens the conclusion.

C) Percapita consumption of meat has not increased substantially in recent years in those countries from which Baurisia is likely to import meat. Wrong - Out of scope. The conclusion depends upon whether or not Baurisia is importing grain.

D) It is more economical for Baurisians to import meat than grain. Correct - If it is more economical to import meat than grain, then Baurisia is more likely to import meat than to import grain. Thus, the conclusion is weakened.

E) During Baurisia's years of growing prosperity, the country's population has remained relatively stable. Wrong - Neutral. Even if the country's population has remained relatively stable, the country is not more or less likely to import grain.

IMO D

In Conclusion is: Will become the importer of grain.

But in premise its said that : several pounds of grain need to make one pound of meat.
To attack the conclusion the correct answer would say that importing grain will become more increase in cost.

So D) says Importing meat is more economical.
Answer : D)

The country of Baurisia has, until now, been self-sufficient in both grain and meat.---------This line denotes a fact or premise. However, with growing prosperity in Baurisia has come a steadily increasing per capita consumption of meat, an it takes several pounds of grain to produce one pound of meat. ---/** This denotes the basis of the argument/** Therefore, since per capita income in Baurisia is almost certain to rise further but increases in domestic grain production are highly unlikely,-----/**This denotes the fact/** Baurisia is soon to become an importer of grain.- This is the conclusion of the argument.
Which of the following, if true, most seriously weaken the argument?

A) When people increase their consumption of meat, they also tend to increase their consumption of grain.
B) The per capita consumption of meat in Baurisia is roughly the same accross all income levels.
C) Percapita consumption of meat has not increased substantially in recent years in those countries from which Baurisia is likely to import meat.
D) It is more economical for Baurisians to import meat than grain.
E) During Baurisia's years of growing prosperity, the country's population has remained relatively stable.

The concept says that you can't deny the premise/fact/evidence, but you can deny the reasoning. the reasoning here is more grain will be required to produce meat. One more fact in the argument is increases in domestic grain production is unlikely.

Let's say that in place of option D, it would have been that a viral crop disease has crippled the main country where the Baurisia is likely to import the grain from.
.
Which one would be correct then?

Any expert. help me to get deep into this.

I didn't think it was D because I assumed that maybe they won't import meat as it doesn't or won't have the same quality as the locally grown meat.
Did I make another unnecessary assumption? I was very confused between B and D..

I'm little bit confused about option C.to weaken the argument we need to find two alternate way.One way is to import meat or another way is to produce more grain.Now both C and D are talking about importing meat but C is a little bit masked and D is direct.So why C is not the right choice??

The argument indicates that the requirement of meat in Baurisia is going to increase (premise 1), and therefore the requirement of grain is also going to increase (conclusion), because one pound of meat production requires several pounds of grain (premise 2). However the argument assumes that the only source of meat in Baurisia is grains; the argument overlooks the possibility that meat can be supplied by some other means, such as, by importing. Therefore a comparison between grain import and meat import would be a good choice for answering this question. Option D makes this comparison and thereby attacks the link between the premise 2 and conclusion.

Option C does not make it clear whether the price of meat would be low enough in those likely exporting countries so as to make meat import more economical than grain import. No Information is given about grains in this option. Moreover an additional assumption is required that higher consumption results in higher price. Option D is a more direct way and leaves no uncretainty about the advantage of meat import over grain import. Therefore option D is better than option C.

there is a question discussing the same topic and it is an assumption question. If the option B is changed into a new sentence that discusses the grain instead, then B is the assumption.
A strengthens the question while D weakens it.

How to Attack a Causal Conclusion

Whenever you identify a causal relationship in the conclusion of a GMAT problem, immediately prepare to either weaken or strengthen the argument. Attacking a cause and effect relationship in Weaken questions almost always consists of performing one of the following tasks:

A. Find an alternate cause for the stated effect

Because the author believes there is only one cause, identifying another cause weakens the conclusion.

B. Show that even when the cause occurs, the effect does not occur

This type of answer often appears in the form of a counterexample. Because the author believes that the cause always produces the effect, any scenario where the cause occurs and the effect does not weaken the conclusion.

C. Show that although the effect occurs, the cause did not occur

This type of answer often appears in the form of a counterexample. Because the author believes that the effect is always produced by the same cause, any scenario where the effect occurs and the cause does not weaken the conclusion.

D. Show that the stated relationship is reversed

Because the author believes that the cause and effect relationship is correctly stated, showing that the relationship is backwards (the claimed effect is actually the cause of the claimed cause) undermines the conclusion.

E. Show that a statistical problem exists with the data used to make the causal statement

If the data used to make a causal statement are in error, then the validity of the causal claim is in question.


Cause : Baurisia has come a steadily increasing per capita consumption of meat

Effect : Baurisia is soon to become an importer of grain

B. Show that even when the cause occurs, the effect does not occur

This type of answer often appears in the form of a counterexample. Because the author believes that the cause always produces the effect, any scenario where the cause occurs and the effect does not weaken the conclusion.

Answer : (D) It is more economical for Baurisians to import meat than grain.

boiled down to B and D. After reading the argument one more time, B is wrong because B strengthens the argument that "consumption in meat will increase"
