(A) Dark beers are generally higher in calories than light beers are. - Per the argument our concern is NOT Higher calories -- OUT

(B) Another survey, conducted among a similar number of women, shows that 8 out of every 10 women prefer light beers to dark ones. -- Survey is about MEN's preference and not about Women's -- Definitely OUT

(C) The survey failed to check the connection between beer preference and the parents' place of birth, even though this may affect the tastes of their children. -- This cannot be the weakener because its not helping us to weaken the conclusion that author made "Most Men in the US prefer Dark Beer". Most Men means Men irrespective of lineage ,Place of Birth, parents or anything what so ever prefer Dark Beer .Argument is not concerned about what type of Man from which background -- OUT

(D) The question concerning men's preference of beer was one among 50 questions which the survey included. -- Thats okay if it was one of the question , this is not at all weakening the Author's conclusion -- OUT

(E) Male US citizens aged 35 and up prefer light beers to dark ones. -- CORRECT Survey was conducted from age 25 to 34 , but the university published the GENERALIZED Results claiming "MOST OF THE MEN" without mentioning the certain Age group of the Men who participated in the survey.

From a specific information

7/10 men between 25 to years of age 34 prefer dark beer over ligt beer

it draws a general conclusion

most men in USA drinks dark beer

.
WE CANT JUST GENERALIZE IT BASED ON A SPECIFIC INFO.

therefore to weaken it we must show that specific info doesnt yield to general conclusion ;option E IS THEREFORE CORRECT.

(A) Dark beers are generally higher in calories than light beers are. -- Calorific content is not important to the conclusion here

(B) Another survey, conducted among a similar number of women, shows that 8 out of every 10 women prefer light beers to dark ones. -- The argument is made about American Men. Out-of-scope

(C) The survey failed to check the connection between beer preference and the parents' place of birth, even though this may affect the tastes of their children. -- Reason for the beer preference is not important

(D) The question concerning men's preference of beer was one among 50 questions which the survey included. -- the number and category of questions are IRRELEVANT

(E) Male US citizens aged 35 and up prefer light beers to dark ones. -- CORRECT, this says that the conclusion is extrapolated from a smaller sample space of only men between the ages of 25 and 34. Overall proportion of men from all age groups would have different results thus weakening the conclusion on behalf of all men.

So, answer should be E

Premise : A survey conducted by the Statistics Department of Duke University shows that 7 out of 10 men in the United States between the ages of 25 and 34 prefer dark beers to light ones.

Conclusion : A publication by Duke university, published two years after the survey was held, claims that most men in the United States prefer dark beers to light ones.

Ques : Which of the following, if true, most seriously undermines the publication's claim?

Pre-thinking : We need to find an option that weakens the author conclusion. Two points which are very much evident from the argument are :
1. The survey was conducted 2 years back and the conclusion for publication is done now.
2. The survey was done specifically for men between the ages 25 and 34. The conclusion is for all the men in US.

Lets analyse the options now :
A) Dark beers are generally higher in calories than light beers are. - Incorrect as this is completely new information and has no impact on the survey or conclusion made.

(B) Another survey, conducted among a similar number of women, shows that 8 out of every 10 women prefer light beers to dark ones. - Incorrect as this is irrelevent, the survey and conclusion in publication are about men's preference and not women's.

(C) The survey failed to check the connection between beer preference and the parents' place of birth, even though this may affect the tastes of their children.Incorect as this option again does not give any information that weakens the conclusion.

(D) The question concerning men's preference of beer was one among 50 questions which the survey included. - Incorrect as this is irrelevent to the survey result or conclusion made.

(E) Male US citizens aged 35 and up prefer light beers to dark ones. - Correct as this tells us that different age group prefer otherwise and the conclusion made is not reliable.

A survey conducted by the Statistics Department of Duke University shows that 7 out of 10 men in the United States between the ages of 25 and 34 prefer dark beers to light ones. A publication by Duke university, published two years after the survey was held, claims, on the basis of the aforementioned survey, that most men in the United States prefer dark beers to light ones.

Which of the following, if true, most seriously undermines the publication's claim?

Okay, so this is a weaken question.
According to the premise, 7 out 10 men of age group 25-34 prefer dark beer over light ones. The publication used this survey and extrapolated for all men
(conclusion)in US.
Now if we get an option that attacks the generalization, that option will help us shortlisting the answers.


(A) Dark beers are generally higher in calories than light beers are.
There is no case made for calories in either the premise or the conclusion.

(B) Another survey, conducted among a similar number of women, shows that 8 out of every 10 women prefer light beers to dark ones.

We are talking about males and not females here.

(C) The survey failed to check the connection between beer preference and the parents' place of birth, even though this may affect the tastes of their children.
This again won't matter as the publication used the survey after 2 years

(D) The question concerning men's preference of beer was one among 50 questions which the survey included.
This question gives information about survey, but it is not attacking the conclusion.

(E) Male US citizens aged 35 and up prefer light beers to dark ones
This will attack the conclusion as the generalization will not work according to this option.
ANSWER - E

A publication by Duke university, published two years after the survey was held, claims, on the basis of the aforementioned survey, that most men in the United States prefer dark beers to light ones.

Which of the following, if true, most seriously undermines the publication's claim?


(A) Dark beers are generally higher in calories than light beers are.
- irrelevant to the conclusion drawn.

(B) Another survey, conducted among a similar number of women, shows that 8 out of every 10 women prefer light beers to dark ones.
- The conclusion makes a statement about men; the results obtained regarding women's preference of beers are irrelevant to the conclusion cited.

(C) The survey failed to check the connection between beer preference and the parents' place of birth, even though this may affect the tastes of their children.
- irrelevant to the conclusion cited.

(D) The question concerning men's preference of beer was one among 50 questions which the survey included.
- does not weaken the conclusion.

(E) Male US citizens aged 35 and up prefer light beers to dark ones. - the survey surveyed men aged between 25 and 34; the conclusion makes a statement on the 'men' in general (not referring to a particular age category). So, what may be true for the survey respondents may not reflect the preferences of those men who fall outside this age category. (E) mentions this perfectly. Hence, (E) is the right answer choice.

A publication by Duke university, published two years after the survey was held, claims, on the basis of the aforementioned survey, that most men in the United States prefer dark beers to light ones.

Which of the following, if true, most seriously undermines the publication's claim? Weaken

Pre-thinking: Study is about men b/w 25 to 34 and conclusion is drawn about all the men. Also there's a big time gap b/w conducting the survey and actual publishing of the results

(A) Dark beers are generally higher in calories than light beers are. OOS

(B) Another survey, conducted among a similar number of women, shows that 8 out of every 10 women prefer light beers to dark ones. Women's preference is OOS. (Please don't get me wrong women's preference is OOS only for this argument otherwise i would always go with what the lady says :P )

(C) The survey failed to check the connection between beer preference and the parents' place of birth, even though this may affect the tastes of their children. Place of birth & origin irrelevant

(D) The question concerning men's preference of beer was one among 50 questions which the survey included. OOS

(E) Male US citizens aged 35 and up prefer light beers to dark ones. Weakens the argument by saying the argument just talked about a segment of men and drew conclusion about the entire male population
