keep many weapons to attack argument. evidence can not be representative. causal relation can be reversed or a third cause comes in.

the key to cr success is ability to attack the argument. find out the thing and conditions, in which argument fall apart.

Could anyone correct my logic?

I chose D.

For the reason that the many computer owners in the United States have enough leisure time that spending significant amounts of time on the computer still leaves ample time for watching television.

So if they are not watching tv some other reason is there i.e. other than computer use because of which they are not interested in watching television.

Hi mikemcgarry,

Please explain as to why (D) or (E) is wrong.

Quote:
Which of the following most logically completes the argument?

The growing popularity of computer-based activities was widely predicted to result in a corresponding decline in television viewing. Recent studies have found that, in the United States, people who own computers watch, on average, significantly less television than people who do not own computers. In itself, however, this finding does very little to show that computer use tends to reduce television viewing time, since _______.

(A) many people who watch little or no television do not own a computer.

(B) even though most computer owners in the United States watch significantly less television than the national average, some computer owners watch far more television than the national average.

(C) computer owners in the United States predominately belong to a demographic group that have long been known to spend less time watching television than the population as a whole does.

(D) many computer owners in the United States have enough leisure time that spending significant amounts of time on the computer still leaves ample time for watching television.

(E) many people use their computers primarily for tasks such as correspondence that can be done more rapidly on the computer, and doing so leaves more leisure time for watching television.

We are told that people who own computers watch significantly less television than people who do not own computers. But does that mean that computer use tends to REDUCE television viewing time? According to the author, it does not.

In other words, the author's conclusion is that the findings from the study do "very little to show that computer use tends to reduce television viewing time." We need an answer choice that supports this conclusion:

Quote:
(D) many computer owners in the United States have enough leisure time that spending significant amounts of time on the computer still leaves ample time for watching television.

Choice (D) tells us that the computer users are not interested in watching television. But would those people be MORE interested in watching television if they did not own computers? Perhaps they would not, and that would support the author's point of view. But perhaps they WOULD watch more television if they did not own computers, and that would go against the author's argument.

Choice (D) may or may not support the author's conclusion, so it is not the best answer.

Quote:
(E) many people use their computers primarily for tasks such as correspondence that can be done more rapidly on the computer, and doing so leaves more leisure time for watching television.

Choice (E) suggests that computer use leaves more time for television watching. But we already know that people with computers watch less television that people without computers.

Sure, (E) suggests that computer users would have less time for television if their computers were taken away. But we have no way of knowing whether computer owners would actually watch more or less television if their computers were taken away.

If people with computers watch less television, why can't we conclude that computer use tends to reduce television watching time? Choice (E) does not answer this question, so it should be eliminated.

Quote:
(C) computer owners in the United States predominately belong to a demographic group that have long been known to spend less time watching television than the population as a whole does.

Choice (C), on the other hand, does answer this question. (C) tells us that computer owners belong to a group that spends less time watching television. So these people have always watched less television. It just so happens that these people also tend to own computers, but computer use did not cause them to watch less television. They've always watched less television, so the finding is not related to the growing popularity of computer-based activities.

(C) is the best answer.

GMATNinja, Could you please explain why A is irrelevant?
The conclusion states that computer use tends to reduce television viewing time. So when computer use occurs(cause), then people watch less television(effect).
We should weaken this conclusion.
I think A weakens the conclusion by showing that when cause does not occur, effect occurs.
What did I miss?

Debate: Does Computer usage reduces TV viewing?

Study: Computer owners view less TV in comparison to others.

Author's Conclusion: This study regarding "Computer ownership" cannot be extrapolated to prove that actual "Computer usage" leads to decline in TV viewing.

Simply stated: Computer Usage does​ not lead to reduction in TV viewing.

As lead-in word is "since", Correct Ans: should provide an alternate reason to strengthen the Conclusion.

Ans C does exactly that by providing 'demography' (and not 'computer usage') as an alternate reason towards reduction in TV viewing.

Now, Ans D and E are very confusing Ans Choices and difficult to eliminate without careful logic.

Either choice focuses on the "time" factor and suggests that "Computer Usage" results in "enough spare time" for TV viewing.

Does this strengthen the Conclusion that "Computer Usage does​ not lead to reduction in TV viewing. "
Ans is No.
Eg. Even though Computer Owners have more time to watch TV, these guys get so contented working on a computer that they don't feel like watching a TV.:
So Computer usage does in fact leads to low TV viewing.
This becomes on opposite statement that weakens the Conclusion.

Hi UkrHurricane, I want to share my thoughts.
the conclusion is that the reduce television is because of the computer use,
A says those who watch little or no television do not own a computer, it does not show "reduce" in conclusion.
So i think it is not correct.

If you have any more ideas, please share, i am glad to discuss with you.

Have a nice day
