C is right.

Essentially we have to weaken the argument.

We have to prove that even though people who own computers watch less television, it does not change the data for the national average.

One way to prove that would be if these people did not watch television even before the advent of computers. So there would be no marked shift in the television viewing hours with or without computers. C states this and is thus right.

yes C is right.
See the linkage: usage of Recent in argument and usage of long been known in option C.

A. is out of scope for me because here all we care is computer use with people having a computer.
B. is not correct, i dont like most and this option and it itself affirm that people watch less tV and this is what we need to explain why people using Computer watch less TV
D. cant explain why
E is out of scope.. doing something else with computer is not mentioned in the CR
C. can be the answer because it says that poeple in the research watched less TV becuase they themselves usually dont watch or dont spend a lot of time to watch tv

"Target Test Prep is the closest to the official version of the GMAT exam, about 99% accuracy in terms of the quality and quantity of information. The course has excellently created singular sets of focused lessons and tests for every possible topic that one could come across in the official GMAT exam."

"The TTP course maximizes the efficiency of the time you spend studying. It will take time and effort but I could almost guarantee that if you complete the course exactly as it is laid out you will get an amazing score. They also have a very responsive team willing to help with any questions you might have."

"TTP has two things that I think no other test prep company offers: A teaching approach that reinforces understanding and an attitude that will give you the mental preparedness needed to succeed on the test. TTP gives you a deep understanding of the concept you need to know while teaching you how to think."
