GMAT PREP Question

by valentindima » Mon Feb 02, 2009 1:35 pm
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 likely to become an importer of grain.
Which of the following, most seriously weakens the argument?

1) When people increase their consumption of meat, they also tend to increase their consumption of grain.
2) The per capita consumption of meat in Baurisia is roughly the same across all income levels.
3) Per capita consumption of meat has increased substantially in recent years in those countries from which Baurisia is likely to import meat.
4) It is more economical for Baurisians to import meat than grain.
5) During Baurisia's growing prosperity, the country's population has remained relatively stable.

OA: 4

This was a question that I thought was a home run. Well, it seems it is a curved ball.

Anyone can reason why not 2)

#2 mentions nothing about importing grain and meat and therefore, it's incorrect. It doesn't attack the main argument as effective as #4, which weakens the statement that the country will import grain (#4 states the opposite) and is the most effective weakening statement out of all of the possible answers.

I have dismissed 4) from the start since I was trying to negate the premise, that is that meat consumption will increase, due to increasing income levels.
Or 2) does exactly that: since meat consumption is the same across all income levels, them an increase in income levels will not result in an increase of meat consumption. No increase equals no shortage of grain.

They just let the premise alone and go straight to negating the conclusion using new data. In this case the statement that most seriously weakens the argument, does not weaken the logic, or the premises. Just weakens the conclusion.
I have dismissed 4) as inconsequential, since it did not address the logic or the premises, brought in new data, and looked remarkably similar to the kind of option that has nothing to do with the argument.

Bottom line, we are given two options, both weakening the argument.
One, 4) goes straight to the conclusion using new data. It is indeed the strongest.
The second, 2) negates a premise, is related to the substance of the argument, and by logic weakens the argument. But is weaker.

I am truly lost in this.

This is quite a tricky question, since 2) is certainly tempting. Still, it's important to read the information provided carefully; we know that with rising prosperity there is "a steadily increasing per capita consumption of meat" in Baurisia. It may be that everyone in Baurisia, rich or poor, eats the same amount of meat, but that if everyone had more money, they would all eat more meat. Indeed, the stem implies that people will eat more meat if they have more money - it doesn't matter how this meat eating is distributed among rich and poor.

4) is correct - the stem seems to assume that Baurisia's only option is to import grain. There is an alternative ignored in the question- import meat. If that's more economical, it seems plausible to think that's what they will do.

I don't understand why are we considering which of the two (meat or grain) is more economical? There is nothing indicated in the passage concerning Baurisia being economical.

Can someone kindly explain this please?

That the expense of importing grain goes unmentioned in the passage is not important here. We have a passage with this structure:

"Because of certain circumstances, Barusia will choose to do Plan A."

It certainly weakens the conclusion if the following is true:

"Plan B achieves the same goals as Plan A, and there are reasons Barusia will probably prefer Plan B".

That's what answer D says, essentially.

Ian,

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 likely to become an importer of grain.

doesn't the bold part kill the idea that something else can be imported?

I am not questioning the OA here. I am just trying to understand what part of the argument should hint me in selecting (D)?

No, the country is planning to import grains just because with the increase in the consumption of meat the country will need more grains to produce meat as it takes several pounds of grain to produce one pound of meat and grain production is not likely to increase in the country.

So, the country is likely to import meat itself, if it is more economical to import meat than to import grains.

If they don't need to make more meat themselves, then they won't need more grain. They have (at least) two options:

-they can try to make more meat, which means they will need more grain, and since they can't grow more grain, they would need to import grain;

-or they can keep their own meat production the same, meaning they won't need any more grain, and import meat to meet demand.

The argument in the question stem is a 'tunnel vision' kind of argument: it draws a conclusion about a likely course of action without considering alternatives that might achieve the same goals.

Glad to get it correct in the first attempt.

The argument provides an evidence that supports my conclusion. (Evidence: More meat requires more grain .Conclusion: Thus import grain)

Answer choice D says that there are other reasons that MAY not lead me to the stated conclusion. Hence it weakens!!!
