For many years, theoretical economists characterized humans as ration

1)For many years, theoretical economists characterized humans as rational beings relentlessly bent on maximizing purely selfish reward. However, results of an experimental economics study appear to contradict this view. It is clear that the however signals a change between what was said before and after it: economists believe human beings are rational, however results of the study say otherwise, i.e. that humans are not rational. The passage then goes on to show that humans do not act rationally in the expriements: If, in fact, people are selfish and rational, then the proposer should offer the smallest possible share, while the responder should accept any offer, no matter how small: after all, even one dollar is better than nothing. In numerous trials, however, two-thirds of the offers made were between 40 and 50 percent; only 4 percent were less than 20 percent, further reinforcing this idea: that the study contradicts economists view. answer is D, which clearly describes what the passage is doing.
2)"Behavior in the game did not appreciably depend on the players’ sex, age, or education. Nor did the amount of money involved play a significant role: for instance, in trials of the game that were conducted in Indonesia, the sum to be shared was as much as three times the subjects’ average monthly income, and still responders refused offers that they deemed too small". It implies that money does not play an important role by this we can safely eliminate Option C. Option A and D are out because of extreme answer choices. Option B does not make any sense. Left with option E which is correct answer choice.
3)"while the responder should accept any offer, no matter how small: after all, even one dollar is better than nothing". Option C clearly matches with this notion.
4)"Behavior in the game did not appreciably depend on the players’ sex, age, or education". As per this notion only option D is not mentioned in the passage.

8 minutes and all correct. Passage is very easy and understandable though in some questions, POE is the best choice.
How we usually got many correct answers here and when in actual GMAT, We fade away and falter in many RC's. Experts??? Any view on this behavior??

1. Prethinking: The passage introduces a economists viewpoints . Author says that this view point contradict with the experiment. The experiment couldn’t prove human being is selfish and rational.
Find a choice that says human being is not selfish and not rational.
D correctly matches our prethinking

2. Results of the Ultimatum Game undermine theoretical economists’ characterization of human beings by
Prethinking: showing that human being is not selfish and not rational. There could be some other factors.
E choice matches our prethinking.

3. while the responder should accept any offer, (20) no matter how small: after all, even one dollar is better than nothing
>> Highlighting an example that human can be selfish and rational such that even a small offer can be accepted.
C matches our prethinking

4. Behavior in the game did not appreciably depend on the players’ sex, age, or education. Nor did the amount of money involved play a significant role:
>>A,B, C and E are mentioned
So D is correct answer.

Why can't B be the answer for the first question? Can anyone please explain

All correct.
Total time 4.30 minutes

Good read

5:51, all correct.

I believe this should be a fairly easy passage.

Hi ChattPou,



B is incorrect for Question 1, as the purpose of the passage is not to study that the behavior of human beings may be motivated by factors other than selfishness, its simply to use a study to challenge what economists already considered to be true. The purpose of the passage to use the study to point out that humans are not selfish, not whether their economic behavior is motivated by factors other than selfishness.

Hope This Helps.
Thanks.

1. The primary purpose of the passage is to

A. provide evidence in support of the view that human beings are essentially rational and selfish
B. use a particular study to challenge the argument that the economic behavior of human beings may be motivated by factors other than selfishness
C. compare certain views about human nature held by theoretical economists with those held by experimental economists
D. describe a study that apparently challenges theoretical economists’ understanding of human economic behavior
E. suggest that researchers may have failed to take into account the impact of certain noneconomic factors in designing a study of human economic behavior

Using POE,i was left with C and D.
I tried to differentiate between the first word (Compare vs Describe).
And felt compare would be apt word to convey the primary purpose.
Can some please explain why C is incorrect?

Answer : suggesting that people’s economic behavior might in part be motivated by factors other than selfishness.

Doesnt the below lines contradict the above answer. Because the author ruled out quite many factors by saying they didnt impact the behavior in game?

Behavior in the game did not appreciably depend on the players’ sex, age, or education. Nor did the amount of money involved play a significant role: for instance, in trials of the game that were conducted in Indonesia, the sum to be shared was as much as three times the subjects’ average monthly income, and still responders refused offers that they deemed too small.

Hi v1987,

Let me know if this helps.


C is incorrect because nowhere the author is comparing the views held by theoretical economists with those held by experimental economists. The author only mentions a particular view held by theoretical economists and how that is contradicted by experiments.
We cannot infer any comparison throughout the passage. Comparison would mean discussing and analyzing both the views, but in the passage, author only mentions information regarding the experiments that contradicts the view.


Thanks.

Hi v1987,

I don't see the above mentioned lines contradicting the answer. The lines mentioned mean that even though the sum offered for share was as much as three times the subjects’ average monthly income, the subject's still refused to take it, meaning that since neither age, sex, education or money played a signification role, then may be their interests were guided by reasons other than selfishness.


Hope This Helps.
Thanks.

Question 1

(C) introduces the views of two different types of economists: theoretical and experimental. Then, it indicates that the passage compares the views of each of these types of economists.

The problem is that the passage does not compare the views of two different types of economists. In fact, it doesn’t even mention experimental economists. It details the traditional view of theoretical economists and proceeds to describe an experiment that seems to undermine this view. So, the comparison is between the view (singular) of theoretical economists and an experiment, NOT the views (plural) of one type of economist and the views (plural) of another type of economist.

That's why you can eliminate (C).

Question 2

Question 2 asks how the results of the Ultimatum Game undermine theoretical economists’ characterization of human beings. These economists characterize humans as being motivated only by selfishness. The results of the game undermine this characterization by suggesting that selfishness alone does not explain humans’ economic behavior.

Sure, the results rule out other potential factors that could influence the players’ behavior. But none of those are part of the economists’ characterization of humans. The economists are concerned with selfishness, and the game undermines the economists’ characterization by indicating that selfishness alone cannot account for all of the players’ behavior, even if the passage rules out other influences as well.

So (E) is the best answer choice.

I hope that helps!

Dear GMATNinja
Regarding the question 1
I had confused to select between choice B and D. Although I then pick up D, I can not convince myself B is wrong.
B. use a particular study to challenge the argument that the economic behavior of human beings may be motivated by factors other than selfishness
D. describe a study that apparently challenges theoretical economists’ understanding of human economic behavior

Then, when I reviewed question 2 with the correct answer E "suggesting that people’s economic behavior might in part be motivated by factors other than selfishness", I confused again about the question 1: Why B is wrong?
Please help

1. The primary purpose of the passage is to

A. provide evidence in support of the view that human beings are essentially rational and selfish
B. use a particular study to challenge the argument that the economic behavior of human beings may be motivated by factors other than selfishness

E. suggest that researchers may have failed to take into account the impact of certain noneconomic factors in designing a study of human economic behavior

Question 1

In question 1, the key to eliminating (B) is the precise wording of the answer choice. It indicates that the passage challenges the argument that humans “may be motivated by factors other than selfishness.” In other words, (B) implies the passage uses the experiment to argue that humans are motivated ONLY by selfishness.

But the passage uses the experiment for the opposite purpose. It uses the experiment to argue human beings are motivated by other factors. So, (B) describes the opposite of what the passage is doing. For that reason, we can eliminate it.

I hope that helps!
_________________

for question 3 , why not option b ?and why option c?
for me option b is correct because it showing low offer were made and it doesnt count it was accepted or rejected .......

Dear Sir
Thank you very much.

Question 3

Question 3 asks us why the author refers to a sum of one dollar. In other words, how does this piece of the passage serve the author's overall argument?

To answer questions like this, it's important to understand the author's purpose as a whole, and from that draw out the reason for including a particular piece of the passage.

Here's a high-level breakdown of the passage:

In the first paragraph, the author:

• Introduces a previously held belief (that humans are "rational beings relentlessly bent on maximizing purely selfish reward").
• Introduces a study that contradicts this belief (the "Ultimate Game").

In the second paragraph, the author:

• Explains how people "should" play the Ultimate Game IF the previously held belief was correct.
  
  • This is where the author brings up the "one dollar" amount
• Explains how people ACTUALLY play the Ultimate Game, which contradicts the previously held belief.

Overall, the author uses a study to contradict the previously held belief that humans are relentlessly rational/selfish.

So, how does the discussion of "one dollar" fit into this overall argument?

There are a couple of issues with (B). First, we don't know that anyone ACTUALLY offered only $1 -- the author just says that people SHOULD offer/accept $1 if they truly were rational/selfish. So, it's not quite right to say that this is an example of something that happened, because we don't know whether it actually DID happen.

In addition, the author's reason for including the $1 discussion isn't just to provide an example of a low offer. Looking back to our passage breakdown, the author includes the example to show how people should act if they were rational/selfish.

(B) doesn't capture that intent, so (B) is out.


This one looks good! The author includes this extreme illustration to show what a rational person would do. Even if your stingy partner only offers you a dollar, it would be rational to accept the dollar instead of leaving with nothing at all. Later in the paragraph we learn that people don't accept small offers, showing that people aren't entirely rational.

(C) captures the author's reason for talking about $1, so (C) is the correct answer.

I hope that helps!
