avigutman - q2) doesn't negating (C), weaken the argument?

Here is how
Quote:

(#1) Option C) There were at least some volunteers who were assigned to do the hard task and felt that the assignment was unfair.

(#2) Negation C) THERE ARE NO volunteers who were assigned to do the hard task and felt that the assignment was unfair.

Rephrasing negation for concision

(#3) ALL of the volunteers who were assigned to do the hard task, felt that the assignment was unfair fair

Now, from #3 : If all volunteers who were assigned to do the hard task, felt the assignment was FAIR

That breaks the argument

Reason :

Group 1 (people who choose the easy task) - say they were fair
Group 2 (people assigned the difficult task) -- this too is fair

Hence, now BOTH GROUPS are claiming "FAIRNESS"

Hence, you can't make the conclusion you made (i.e. the same person will do believe two different things, based on two different scenarios)

OR DO YOU THINK perhaps, #3 really doesn't BREAK THE ARGUMENT but rather just change the premises of the original argument all-together (BOTH GROUPS are claiming FAIRNESS, now) ?

Here's a video analysis of answer choice (C), jabhatta2:

Argument Recap:
In an experiment, volunteers were given a choice between an easy task and a hard task, or to let a computer assign tasks randomly.
Most volunteers chose the easy task for themselves and later justified their decision as fair.
However, when the same scenario was described to another group, most in that group said choosing the easy task would be unfair.
The argument concludes that most people apply weaker moral standards to themselves than to others.

Question:
We need to identify an assumption that the argument relies on (a necessary assumption). An assumption is something unstated that must be true for the conclusion to hold.

Analysis of Each Answer Choice:
(A) At least some volunteers who said they had acted fairly in choosing the easy task would have said that it was unfair for someone else to do so.

Explanation: This option suggests that some volunteers who chose the easy task for themselves would judge others more harshly for doing the same. This supports the idea that people have different moral standards for themselves and for others. If the volunteers don't hold this double standard, the conclusion would weaken. So, this is a required assumption.
Verdict: Correct.

(B) The most moral choice for the volunteers would have been to have the computer assign the two tasks randomly.

Explanation: This statement concerns the moral judgment of the experiment but is not essential to the argument's conclusion. The argument is about comparing moral standards applied to oneself versus others, not about identifying the "most moral" choice.
Verdict: Not necessary. Eliminate.

(C) There were at least some volunteers who were assigned to do the hard task and felt that the assignment was unfair.

Explanation: This answer discusses the feelings of those assigned the hard task, but it doesn’t address the key issue of applying moral standards differently to oneself and others. The argument isn't about how the assigned tasks were perceived, but rather about the fairness of self-judgment.
Verdict: Not necessary. Eliminate.

(D) On average, the volunteers to whom the scenario was described were more accurate in their moral judgments than the other volunteers were.

Explanation: This statement implies a judgment about accuracy, which is outside the scope of the argument. The argument doesn’t require us to compare accuracy; it’s about the difference in moral standards applied to oneself versus others.
Verdict: Not necessary. Eliminate.

(E) At least some volunteers given the choice between assigning the tasks themselves and having the computer assign them felt that they had made the only fair choice available to them.

Explanation: This option suggests that some volunteers believed their decision was the only fair option, but this doesn’t directly support the argument about differing moral standards. The focus is on the self-justification rather than the comparison of moral standards applied to oneself versus others.
Verdict: Not necessary. Eliminate.
Correct Answer: (A)

Important :- This is not a mathematical question. It also does not need to look into tautology. Terms like "some". "all", "none" are not required to be evaluated in this questions as many other answers are trying to do. This is a plain and simple logical question that need sorting the premise and conclusion and finding/matching/adding the assumptions. As simple as that !!

Answer is OPTION A


Visualise this scenario:- You are walking in a locality with lots of shops and restaurants and parks. You see a Punk-Teenager being handcuffed and taken into custody by police.
You ask a nearby bystander:- What is happening?

The old man replies:- That kid was stealing iPhone from the supermarket.

You say :- What a bum I can't tolerate thieves and robbers. They are scum of the world and should be punished by law.

The old man says:- I agree 100% with you. Look at me, I am also very poor but I have never stolen a thing and as god is my witness, I will never ever be a thief, no matter how hard my life become.


15 days later you are again in that place and you see the old man from the previous meeting is being handcuffed and taken into custody for stealing. You are surprised as you remember his last words :-:Look at me, I am also very poor but I have never stolen a thing and as god is my witness, I will never steal ever, no matter how hard my life become."

You rush to him and ask him:- why ???? why did you steal ?

The old man replies :- I had no choice. My wife is very ill and I had no money. I didn't steal money or food or mobiles or perfumes or alcohol. I just stole some medicine for my wife. This is not a crime because I was just trying to save my wife's life.


Now you see how people think the same standard does not apply to them for whatever x,y,z reasons.
(Stealing is crime in the eyes of the laws but this old man thinks stealing medicine is different from stealing an smartphone)
THIS IS the comparison that brings out the main point of the argument:- People apply weak moral standards to themselves than to others.
To bring out this comparison what should happen ( what assumption is required ?) --> That the old man who was against stealing earlier, must have stolen something at a later stage and then have tried to defend his action.

What options says so:-
(A) At least some volunteers who said they had acted fairly in choosing the easy task would have said that it was unfair for someone else to do so.
(A) The old man who said that he stole to save his wife earlier said that stealing was wrong when police arrested the punk teenager for stealing iphone..


notwithstanding
In an experiment, each volunteer was allowed to choose between an easy task and a hard task and was told that another volunteer would do the other task. Each volunteer could also choose to have a computer assign the two tasks randomly. Most volunteers chose the easy task for themselves and under questioning later said they had acted fairly. But when the scenario was described to another group of volunteers, almost all said choosing the easy task would be unfair. This shows that most people apply weaker moral standards to themselves than to others.

Which of the following is an assumption required by this argument?

(A) At least some volunteers who said they had acted fairly in choosing the easy task would have said that it was unfair for someone else to do so.
(B) The most moral choice for the volunteers would have been to have the computer assign the two tasks randomly.
(C) There were at least some volunteers who were assigned to do the hard task and felt that the assignment was unfair.
(D) On average, the volunteers to whom the scenario was described were more accurate in their moral judgments than the other volunteers were.
(E) At least some volunteers given the choice between assigning the tasks themselves and having the computer assign them felt that they had made the only fair choice available to them.
Could not have explained any better than this. Thank you!

GMATNinja Thank you for the explanation. While I completely understand and agree with it, I found myself confused in test-paced mode, mainly due to how the premises and conclusion were structured.

If we simplify the argument:

Premise 1: Most of Group A showed relaxed moral standards toward themselves.
Premise 2: Most of Group B showed strict moral standard toward others.
Conclusion: Therefore, Most people apply weaker moral standards to themselves than to others.

Though I understand that there's a gap between the premises and conclusion-as "most" in certain groups is extended to "most people" in general, as you explained-I was wondering if the answer choice bridging this gap should be considered subtle. Would this argument, as it stands, be considered fairly strong? Is it acceptable to draw a general conclusion about most people from most members of certain groups, or should I generally be cautious of this type of logic?

I still didn't get why D is wrong. if we refer the last few lines when the scenario was described to another group of volunteers, almost all said choosing the easy task would be unfair. This shows that most people apply weaker moral standards to themselves than to others.

We are deriving this conclusion based on what the second group said. But we are not sure how accurate they are in their judgment . For example , if a person says stealing is morally wrong but if that person's judgment can't be trusted. Then obviously whatever this person is saying can be wrong. So as per my understanding D bridges this gap stating that second group was more accurate than the first group.


Can anyone explain why I am wrong??
The author concludes that "most people apply weaker moral standards to themselves than to others."

Notice that the author doesn't ever come out and say what is ACTUALLY right or wrong. He/she just makes a comparison between two groups: people deciding what to do themselves, and people saying what's morally right for others.

So, which group is more "accurate" in their moral assessment? We have no idea, and the author really doesn't care -- he/she just cares that there's a difference in how people assess the morality of a situation.

With that in mind, take a look at (D):
Quote:
(D) On average, the volunteers to whom the scenario was described were more accurate in their moral judgments than the other volunteers were.
We know from the passage that people to whom the scenario was described held a different moral standard than the other volunteers. However, the author's argument does't depend on this standard being more "accurate" in some grand sense. So, the argument doesn't depend on (D).

Compare that to (A):
Quote:
(A) At least some volunteers who said they had acted fairly in choosing the easy task would have said that it was unfair for someone else to do so.

In the argument, the author cites a specific group of people to come to a conclusion about people in general.

But what if the people who participated in the experiment just have a lower moral standard than other people? Then the author's conclusion about people in general falls apart.

So, we need to assume that there's nothing particularly different about the volunteers in the experiment, and that those people would make the same judgment call as other people.

We need to assume (A) in order for the argument to hold up, so (A) is the assumption required by the argument.

I hope that helps!

Trying to come up with rigid rules for CR logic (for example, "When you see evidence based on a group, that is not enough to draw a conclusion that applies to everyone.") is dangerous because it encourages you to rely on those memorized rules instead of thinking really hard about the SPECIFIC wording and context of the passage in front of you.

In this particular case, the author's conclusion is quite strong: "[this experiment] SHOWS that most people apply weaker moral standards...". This specific conclusion doesn't hold unless (A) is assumed.

But a subtly different conclusion might be okay even without choice (A): "This experiment is EVIDENCE that SOME people apply weaker moral standards..." It might not sound terribly different, but this "weaker" (or less definitive) version is much easier to defend.

A better takeaway from this passage is that you need to pay attention to the details, especially in the conclusion. It's really easy to overlook little words such as "most people" or "this shows". Those are the little details that make all the difference, so practice noticing those details and thinking hard about what they mean and how they affect the argument.

That's not as satisfying as a conclusive statement about the strength of certain types of logic, but it's more important for the GMAT.

I hope that helps!

Great explaination but this is what i am tired of, in the exam scenario, by the time i think about all these and imagine and do all these stuff i'll be using 5 questions worth of time, oh and being a non native english speaker, understanding certain terms and comphrending these. like just how??/
