Why is answer C correct?

Tyrone, the conclusion is based upon the assumption that "How people feel" depends on the time they have been treated, while answer C is claiming the exact opposite; "How people feel" will determine the length of treatment and it will make the conclusion proposed(even the whole survey) meaningless :)

Why can't B be the correct answer?

Keti,
(B) Patients who had received treatment for longer than 6 months were more likely to respond to the survey than were those who had received treatment for a shorter time.
Ask yourselves: If this would be true, what would be the outcome?
Well, the influence against the percentage of ALL the people who responded is NONE
There is however influence in the percentage of responders from a certain group the 'longer than six months'-people.
Now the argument states: Longer treatment yields better results.
While, if true there are more responders from a particular group it doesn't imply the returned answers are influenced.
Thus the frequency of responders has no influence on the answer replied.
Niels
PS.
For clarity, if there would have been 50 short responders saying: Splendid! And there are 5000 long responders saying: Yak! The outcome of the survey would be that short treatment is better while B could be true.

I still don't understand why "C" is the answer

Tolu, Niels put it succinctly in the prior post, that the problem makes the claim that efficacy of treatment corresponds to the length of treatment time. Answer C makes this claim invalid, since it does not take into account that people whose treatment is not effective will quit before 6 months.

I was torn between A & C and my gut said C but I hit A. The manner in which this weakens the argument is very obtuse to discern but this explanation helps test takers watch out for these sneaky, somewhat hidden direct connections to the conclusion

So do you work for LSAC? Or is this your own gig you have going here?
