A large survey of scientists found that almost all accept Wang's Law, and almost all know the results of the Brown-Eisler Experiment. But those results together with Wang's Law contradict the Minsk Hypothesis. Therefore, most of the scientists surveyed reject the Minsk Hypothesis.

The argument requires assuming which one of the following?

(A) The scientists surveyed are generally aware that the results of the Brown-Eisler Experiment together with Wang's Law contradict the Minsk Hypothesis.

(B) The scientists in the survey who know the results of the Brown-Eisler Experiment are exactly the same ones who accept Wang's Law.

(C) Almost all of the scientists surveyed are familiar with the way in which the results of the Brown-Eisler Experiment were obtained.

(D) The sample is large enough to be representative of scientists in the field.

(E) Wang's Law has in fact been shown to be true.

ANS A)
The missing gap ibetween presmise and conclusion is stated in the answer and therefore has to be an assumption .

Use negative technique to find the correct answer.

(A) The scientists surveyed are generally aware that the results of the Brown-Eisler Experiment together with Wang's Law contradict the Minsk Hypothesis.
Correct. If the scientists surveyed are unware the contradiction, we can't conclude that they will reject the Minsk Hypothesis.

The logic is like when we easily make a comparison between two known things, but hardly to make a comparison between a known thing and an unknown thing, or another thing that is irrelevant to the former.


(B) The scientists in the survey who know the results of the Brown-Eisler Experiment (A) are exactly the same ones who accept Wang's Law (B).
This choice isn't necessarily true. If the group (A) isn't the same as group (B), the conclusion still remains.

(C) Almost all of the scientists surveyed are familiar with the way in which the results of the Brown-Eisler Experiment were obtained.
What if all of them are unfamiliar with the results? They still accept the results, so the conclusion still remains.

(D) The sample is large enough to be representative of scientists in the field.
Actually, the passage already mentioned that "a large survey" and "almost". Those words mean "large enough"
to go to the conclusion.


(E) Wang's Law has in fact been shown to be true.
If Wang's Law is wrong, the scientists still accept the results and reject the Minsk Hypothesis.

So i get how negating the correct answer breaks the assumption. How does "scientists generally don't know..." break the conclusion that "most scientists reject the minsk"? I bet its something super simple and im just missing it being tired and what not but I'd love to know.

The argument requires assuming which one of the following?

(A) The scientists surveyed are generally aware that the results of the Brown-Eisler Experiment together with Wang's Law contradict the Minsk Hypothesis. -Correct. We know that the scientists accept the W Law and know the results of BE Experiment. We know that the scientists reject M Hypothesis. Thus this is acting as a link between the two statements.

(B) The scientists in the survey who know the results of the Brown-Eisler Experiment are exactly the same ones who accept Wang's Law. -This is as stating the premise in different terms.

(C) Almost all of the scientists surveyed are familiar with the way in which the results of the Brown-Eisler Experiment were obtained. -Irrelevant

(D) The sample is large enough to be representative of scientists in the field. -Irrelevant

(E) Wang's Law has in fact been shown to be true. -Irrelevant

I do not like this question. The fact that A is the answer (i.e. must be true) implies that the only way scientists could reject Minsk is by knowing Wang + BE. Is it not possible that a scientist rejects the Minsk hypothesis for a reason other than knowing Wang + BE?

Hi,

Amongst all the choices option A is the only viable solution. There will be many choices that you won't find good, but they will be correct answers. People who create these questions spend tons of time creating such questions, no wonder we all get confused.
Try to find the rational behind each question and its options. That will be really helpful in the long run.

I hope that helps.
Regards

The key here lies in the wording of the question. The question says "almost all accept", "almost all know the results" and "most of the scientists". These make option B wrong and A correct.

A large survey of scientists found that almost all accept Wang's Law, and almost all know the results of the Brown-Eisler Experiment. But those results together with Wang's Law contradict the Minsk Hypothesis. Therefore, most of the scientists surveyed reject the Minsk Hypothesis.

The argument requires assuming which one of the following?

[Pre-thinking: In the survey, all the scientists accept the WL and all know the results of BES experiment. The conclusion drawn is that most of the scientists surveyed reject the MH because the results together with WL contradict the MH. Therefore, the assumption could be: The scientists surveyed are aware of the contradiction.]

(A) The scientists surveyed are generally aware that the results of the Brown-Eisler Experiment together with Wang's Law contradict the Minsk Hypothesis.
[As per the pre-thinking]

(B) The scientists in the survey who know the results of the Brown-Eisler Experiment are exactly the same ones who accept Wang's Law.

[How does it fill up the missing link that the scientists reject the MH?]

(C) Almost all of the scientists surveyed are familiar with the way in which the results of the Brown-Eisler Experiment were obtained.

[How the results are obtained has nothing to do with the missing link.]

(D) The sample is large enough to be representative of scientists in the field.

[The argument just talks about the scientist surveyed and not all scientists in general. Moreover, nothing to fill up the missing link.]

(E) Wang's Law has in fact been shown to be true.

[Doesn’t help fill up the missing link.]

Option A.
