Many a people are pointing out BLATANTLY WRONG options, based on god knows what criteria.
FIRST understand the argument.
THEN understand the question.

WE have to evaluate the ARGUMENT. THE ONLY WAY TO CHOOSE A CORRECT OPTION IN EVALUATE AN ARGUMENT IS TO GET TWO POLARISING OPPOSITE ANSWERS WHEN WE ASK A COMMON QUESTION

The stimulus talks about FREE TIME -the time that a person spend time on computer and thus cannot afford to spend watching TV.
But surprisingly the person is doing both.
how can this be possible.
This can only be possible when he is taking into account the time he spends at work as the time spend on computers.

CURRENTLY IN THE SURVEY HE IS BEING ASKED ""DOES YOUR TV WATCHING TIME HAS DECREASED BECAUSE OF COMPUTER"?

OBVIOUSLY THE PERSON WILL SAY NO, BECAUSE HE IS INCLUDING HIS WORK TIME.

THE CORRECT QUESTION THAT NEEDS TO BE ASKED IS "AFTER COMING HOME, DO YOU SPEND THE SAME TIME IN WATCHING TV AS YOU USED TO DO BEFORE COMPUTERS?"

Now if the person have a computer at home and uses it a lot,then he will say:- yeah man.. i don't watch tv anymore.. i surf and google and stuff.
Now if the person do not have a computer then he will say:- no man.. i watch the same programs , same time.. nothing changed.

THIS IS THE ONLY WAY TO EVALUATE AN ARGUMENT. LEARN IT, UNDERSTAND IT AND USE IT. IT IS CALLED VARIANCE TEST.

SO the correct answer is E

Which of the following would it be most useful to determine in order to evaluate the argument?

A. Whether a large majority of the survey respondents reported watching television regularly

B. Whether the amount of time spent watching television is declining among people who report that they rarely or never use computers

C. Whether the type of television programs a person watches tends to change as the amount of time spent per week using computers increases

D. Whether a large majority of the computer owners in the survey reported spending increasing amounts of time per week using computers

E. Whether the survey respondents' reports of time spent using computers included time spent using computers at work

Note: There are two questions available with the similar stimulus and same first line but different question. The other question (complete the argument) is discussed in: the-growing-popularity-of-computer-based-activities-was-q2-80846.html

The growing popularity of computer-based activities was widely expected to result in a decline in television viewing, since it had been assumed that people lack sufficient free time to maintain current television-viewing levels while spending increasing amounts of free time on the computer. That assumption, however, is evidently false: in a recent mail survey concerning media use, a very large majority of respondents who report increasing time spent per week using computers report no charge in time spent watching television.

As per : The growing popularity of computer-based activities was widely expected to result in a decline in television viewing
Earlier
total free time =10 hrs week
Computer time = 5 hrs
TV time = 5 hrs

Now
total free time =10 hrs week
Computer time = 9 hrs
TV time = 1 hr

But as per the argument '

in a recent mail survey concerning media use, a very large majority of respondents who report increasing time spent per week using computers report no charge in time spent watching television.

total free time =10 hrs week
Computer time = 5 hrs
TV time = 5 hrs

Now
total free time =14 hrs week
Computer time = 9 hrs
TV time = 5 hr

Which of the following would it be most useful to determine in order to evaluate the argument?

A. Whether a large majority of the survey respondents reported watching television regularly

Assume this: Majority of people
total free time =10 hrs week
Computer time = 5 hrs
TV time = 0 hrs

Now
total free time =14 hrs week
Computer time = 9 hrs
TV time = 0 hr

Then definitely it changes our conclusion.

B. Whether the amount of time spent watching television is declining among people who report that they rarely or never use computers

C. Whether the type of television programs a person watches tends to change as the amount of time spent per week using computers increases

D. Whether a large majority of the computer owners in the survey reported spending increasing amounts of time per week using computers

E. Whether the survey respondents' reports of time spent using computers included time spent using computers at work

The growing popularity of computer-based activities was widely expected to result in a decline in television viewing, since it had been assumed that people lack sufficient free time to maintain current television-viewing levels while spending increasing amounts of free time on the computer. That assumption, however, is evidently false: in a recent mail survey concerning media use, a very large majority of respondents who report increasing time spent per week using computers report no charge in time spent watching television.

Computer use.....Increasing....................Television viewing hours......decreasing (False)
Survey: Computer hours have increased BUT no change in time spent watching tv.

There can be two cases:
1) As mostly happens with us. Multitasking.........working on our devices and also watching tv.
2) Time spent on computers have increased but during work hours.

A. Whether a large majority of the survey respondents reported watching television regularly
REGULARLY: This word is inconclusive
I can watch tv regularly either for 1 hour or 10 hours.

B. Whether the amount of time spent watching television is declining among people who report that they rarely or never use computers
This is not our target sample. OUT OF SCOPE

C. Whether the type of television programs a person watches tends to change as the amount of time spent per week using computers increases
OUT OF SCOPE

D. Whether a large majority of the computer owners in the survey reported spending increasing amounts of time per week using computers
incorrect. It really does not help in understanding the amount of time spent on tv has increased or decreased?

E. Whether the survey respondents' reports of time spent using computers included time spent using computers at work
If this is the case then the respondents' have time to watch tv at home. So CORRECT.

Note: There are two questions available with the similar stimulus and same first line but different question. The other question (complete the argument) is discussed in: http://gmatclub.com/forum/the-growing-p ... 80846.html

Computer-based Activities

Step 1: Identify the Question

The words useful to determine and evaluate the argument in the question stem indicate that this is an Evaluate the Argument question.

Step 2: Deconstruct the Argument

Comp expctd →  < TV, since assumed not enough free time
© False! Survey: > comp but same TV!

(Note: the © symbol is one way to indicate the conclusion in your notes.)
The argument debunks an expectation: people aren’t replacing their TV time with more computer time. They’re watching the same amount of TV and increasing their computer time. (Perhaps they’re using both devices at the same time?)

Step 3: Pause and State the Goal

On Evaluate questions, each answer will be in the form of a question or a “whether x is true” statement. The correct answer will address an issue on which the argument hinges, depending on whether that statement is true: one way, the argument will be strengthened; the other way, the argument will be weakened.

Step 4: Work from Wrong to Right

(A) If a large majority do watch TV regularly, then the argument is not impacted one way or the other. Likewise, if a large majority do not watch TV regularly, the argument is not impacted. The argument does not depend on how regularly the respondents watched TV.
(B) People who don’t (or rarely) use computers are the wrong group of people to investigate. The argument is concerned with people who are using computers (and who are increasing their usage).
(C) If people watch the same kinds of programs, the argument is not impacted. If people watch different programs, the argument is not impacted. The argument does not depend upon the types of programs people watch.
(D) Even if a large majority kept increasing their computer usage week by week, the argument is not impacted; the respondents still reported spending the same amount of time watching TV each week.
(E) CORRECT. If the increase in computer usage is occurring at work, then this increase wouldn’t be expected to impact TV viewing during free time at home. This information would weaken the claim that the original assumption was false, since the assumption was based specifically on computer usage at home. If, on the other hand, respondents are using computers more at home, then the survey does strengthen the claim that the original assumption was false.

OA:E.

I can understand E is the correct answer,but I can not understand why A is not correct.
My understanding for A is:If the survey respondents are never watching TV, so the conclusion of no change in watching TV has no sense(because they never watch TV), so if in this situation answer A can weaken the argument.

Tough question

basically the argument says that IF you spot the reason why the people dedicate more time to pc AND at the same time the amount of time dedicate to TV is more or less the same of before.....you have the right answer.

E says that the amount of time dedicated to PC is not a single time but shared, between two situations. In other words, if you have 10 hours dedicated to the computer and 10 hours dedicated to TV is not possible. BUT in E the time spent to PC is not 10 hours but 10 hours combined bewtween home AND office, so this time is not 10 + 10 but 10 combined. As result, you have time to dedicate to watch TV, eventually the other 10 hours

Hope is clear

I initially thought that this question is about representativeness of the survey group (typical mistake in survey type q-s). If the survey group didn't have any regular tv watchers than it would mean that it is irrelevant for the argument.

I will share my understanding here. Even I went with A initially. Let us see the variance test for option A.
Yes-Majority of television respondents reported watching TV regularly. This might seem as though it supports the conclusion. But this majority either watches 1 minute everyday(or lets just say they watch zero hours everyday as per your argument) or 18 hours everyday. both are possible. If it's 1 minute everyday, it doesn't negates the conclusion . If it's 18 hours, it strengthens the conclusion.
The No answer surely negates the conclusion.
It should support conclusion in one extreme and negate it in the other extreme. Hence A is wrong.
This is my observation. Correct me if I'm wrong.

The growing popularity of computer-based activities was widely expected to result in a decline in television viewing, since it had been assumed that people lack sufficient free time to maintain current television-viewing levels while spending increasing amounts of free time on the computer. That assumption, however, is evidently false: in a recent mail survey concerning media use, a very large majority of respondents who report increasing time spent per week using computers report no change in time spent watching television.

CAT => decline in TV viewing
because people have limited time so either they will compensate for one or other activities
this is false.

Conclusion :- a very large majority of respondents who report increasing time spent per week using computers report no change in time spent watching television.
CAT => decline in TV viewing (have to evaluate this)
Pre-thinking:-
1> difference in terminology FREE TIME and time spent per week

Which of the following would it be most useful to determine in order to evaluate the argument?

B. Whether the amount of time spent watching television is declining (among people who report that they rarely or never use computers)
people lack sufficient free time to maintain current television-viewing levels while spending increasing amounts of free time on the computer => so we are concerned with the people for whom amounts of free time on the computer ON THE COMPUTER IS INCREASED.

E. Whether the survey respondents' reports of time spent using computers included time spent using computers at work
No- the survey respondents' reports of time spent using computers doesn't include time spent using computers at work. THAT means something is wrong with total time considered.

yup, the official question looks complex but clear. For example, unofficial questions will have "which is most useful to determine in this question", while official will have "evaluate". See the difference?

Using POE, only E is the most probable to be the correct answer.
A has many flaws.

The first time I encounter this question, and got wrong. I hardly understand the difference between A and E.
Now, after heavily practicing, I can tell that E is the answer.

A is wrong for several reasons.
1/ watching regularly is out of scope, the conclusion is about no change in time of watching TV
2/ whether majority watches regularly or not does not help.
3/ A does not give new information in addition to no change in watching time.
4/ A conflicts with the passage. A says regularly while the passage says no change in time.
