Doesn't the premise means that companies are appointing older CEOs now? If yes, then a surely weakens the argument.

No. The argument only says that CEOs tend to be older now. It is not the same as 'companies are appointing older CEOs now.'

Then I agree with C, but I still feel A is a contender.
My explanation: Suppose the survey companies analyse the age of CEOs.The sample consists of 100 CEOs among whom 80 were made the CEO at the age of 45. Now these CEOs are now aged 57, but still can you say that now a days CEOs are getting older. Obviously not!

We are talking about 2 points in time. 20 yrs back the avg age was 40. Today the avg age is 60. The CEOs are definitely getting older. The point is not why they are getting older. The company has retained a 60 yr old for the top position. It has not brought in a young gun. They have the freedom to bring in a new guy whenever they desire. It doesn't matter why the company has retained the old guy - his experience or his performance whatever. What matters is that at this point, its CEO is a 60 yr old and the company is fine with it. It is not a lifetime position awarded to the CEOs. If, on average, the companies are happy with the older lot, it means the CEOs are getting older now.

OA is C
Why not B?? :(
C is definitely right but B is also correct.. wht if the avg tenure period is 25 years (assuming) so the average taken 20 years back is bound to be less than what it is now.. is it not??

The average age of chief executive officers (CEO’s) in a large sample of companies is 57. The average age of CEO’s in those same companies 20 years ago was approximately eight years younger. On the basis of those data, it can be concluded that CEO’s in general tend to be older now.

Which of the following casts the most doubt on the conclusion drawn above?

(A) The dates when the CEO’s assumed their current positions have not been specified.
(B) No information is given concerning the average number of years that CEO’s remain in office.

(D) Only approximate information is given concerning the average age of the CEO’s 20 years ago.
(E) Information concerning the exact number of companies in the sample has not been given.


i don't think that c is correct because there is no information about the operating years of a company...

It's an inference you can make. The passage says the average age of CEOs at a large sample of companies is 57. The average age at THOSE SAME COMPANIES 20 years ago was eight years younger. Therefore, the companies have to still exist in order to be surveyed (atleast 20 years old).

The argument concludes that: CEO's in general tend to be older now.
The basis for this claim is that:
1. Avg age of CEO in a large samples of companies is 57.
2. Ava age of CEO in these companies 20 years earlier is 57 -8.

A & B: this does not impact on the CEO avg age currently.
C: These companies have been operating for at least 20yrs. Thus, this cannot represent the general companies. CORRECT.
D: No impact.
E: Not necessary for this number.

I got stuck between C and E.

A is out - it is irrelevant
B - irrelevant
C = looks good, we make a generalization based on a limited sample. this is a major flaw.
D - approximate information given - well, tempting, but not. C is more strong.
E - the number of companies in the sample is irrelevant.

C for me

i m confused this is weaken question why are some posts based on inference , to weaken a conclusion we have to add new information and making the assumption false, C cannot be the assumption , In C we are given with the fact that is already stated in question.

Expert please correct me if i am missing anything.

This is a weaken question. We have to find the conclusion and weaken it.

Premises:

The average age of CEOs in a large sample of companies is 57.
The average age of CEO’s in those same companies 20 years ago was approximately eight years younger.

Conclusion: CEO’s in general tend to be older now.

Notice what the conclusion says: CEOs IN GENERAL tend to be older now. How can you deduce something about CEOs in general now when you have researched CEOs of only those companies which were in operation 20 yrs ago too. What about all the companies that came up in the last 20 years? What if the CEOs of the younger companies are much younger. Then the conclusion weakens. Option (C) points out this flaw in the reasoning. Hence it weakens the conclusion.

idea - if sample size 20 yrs ago and now is not comparable then this argument will be weaken
(A) The dates when the CEO’s assumed their current positions have not been specified. - dates are not going to affect it.
(B) No information is given concerning the average number of years that CEO’s remain in office. - avg num of yrs are not concerned for age
(C) The information is based only on companies that have been operating for at least 20 years. - this is giving right idea for both samples, as it is concluding that thr is no data for companies older then 20 yrs.
(D) Only approximate information is given concerning the average age of the CEO’s 20 years ago. - no sufficient info given for avg age for 20 yrs ago
(E) Information concerning the exact number of companies in the sample has not been given.

Conclusion: CEO’s in general tend to be older now.

(B) No information is given concerning the average number of years that CEO’s remain in office.

This is irrelevant. Does it matter whether the CEO's remain in office for 10 years or for 2 years? Point is, it doesn't matter whether the 20 companies have the same CEOs that they had 8 yrs ago or they change CEO's every year and have been hiring older CEOs. In any case, in those 20 companies CEOs are older today than they were 8 yrs ago. So option (B) does not weaken the conclusion.
