### HideShow timer Statistics

Most people believe that yawning is most powerfully triggered by seeing someone else yawn. This belief about yawning is widespread not only today, but also has been commonplace in many parts of the world in the past, if we are to believe historians of popular culture. Thus, seeing someone else yawn must be the most irresistible cause of yawning.
The argument is most vulnerable to which one of the following criticisms?
(A) It attempts to support its conclusion solely by restating that conclusion in other words.
(B) It cites the evidence of historians of popular culture in direct support of a claim that lies outside their area of expertise.
(C) It makes a sweeping generalization about yawning based on evidence drawn from a limited number of atypical cases.
(D) It supports its conclusion by appealing solely to opinion in a matter that is largely factual.
(E) It takes for granted that yawns have no cause other than the one it cites.

Im between A and E.

X -> Y
seeing someone else yawn -> leads to yawning

This argument is causal. Because it assumes
1) only X -> Y
only (seeing someone else yawn) leads to yawning

2) Reverse causal assumption is wrong i.e. Y does not lead to X
yawning -> does not cause "seeing someone else"

If Z -> Y then it destroys the argument. I think E spells this out.

IMO : E

Compare these 2 sentences:

"Thus, seeing someone else yawn must be the most irresistible cause of yawning"

and

"(E) It takes for granted that yawns have no cause other than the one it cites."

The author does not say anything about other possible causes, and he states that the one he mentions is the most irresistible one, without saying that it is the only one.

I would choose answer A, since the conclusion (seeing someone yawn is the most irresistible cause for yawning), is exactly the same as that of other people (all those who believe the same).
This reasoning process is something like this: "Tom and Sarah think that the sky is blue, thus the sky must be blue".
It is simply restating the previous conclusion...
But I don't know, I may be wrong...OA?

Lets wait for OA. "must be the most" in the conclusion triggered my reasoning.

This belief about yawning is widespread not only today, but also has been commonplace in many parts of the world in the past, if we are to believe historians of popular culture. Thus, seeing someone else yawn must be the most irresistible cause of yawning.
The argument is most vulnerable to which one of the following criticisms?

evidence: "Most people believe now and in past"
conclusion: "seeing someone else yawn must be the most irresistible cause of yawning"

(A) It attempts to support its conclusion solely by restating that conclusion in other words. (wrong)
(B) It cites the evidence of historians of popular culture in direct support of a claim that lies outside their area of expertise. (wrong as area of experties not listed in argument)
(C) It makes a sweeping generalization about yawning based on evidence drawn from a limited number of atypical cases.(wrong as there are no atypical cases)
(D) It supports its conclusion by appealing solely to opinion in a matter that is largely factual. (correct as it makes the evidence less credible)
(E) It takes for granted that yawns have no cause other than the one it cites.(can be out compared to D but it also weakens to a degree the argument.)

How there can be so many interpretation of the same stimulus?

Most people believe that yawning is most powerfully triggered by seeing someone else yawn.
This belief about yawning is widespread not only today ----> is something like
Sun rises in the East. ( a fact)

You can realize from the passage that it is inferred as a fact that yawning is caused by seeing someone yawn, solely on the basis of popular belief that says so.

yawning is a scientific behavior, a fact, thus the argument is weak in that it concludes a fact from a commonly held opinion or belief.

Thanks,

Most people believe that yawning
if we are to believe historians
Thus, seeing someone else yawn

conclusion is just based on believing the fact that yawning is most powerfully triggered by seeing someone else yawn.

(D) It supports its conclusion by appealing solely to opinion in a matter that is largely factual.

hope this helps.

If there´s any other question you want to know the OA and I have not posted yet, please let me know.
I post OA after a good discussion, but I think that from now on I will post the OA with the question.

I especially appreciate your concern for revealing the answer, I cant help but look if it's out in the open.
I'm sure you know, but as a reminder..a solution for both sides could be proposed with the tag labeled:
Code:
[spoiler=]A[/spoiler]

Thanks for the question, very challenging indeed.
