It's really important to understand what DIRECTION you should be taking for this question.
We want to weaken Brad's argument. Brad was arguing against Jennifer --> essentially we are trying to find something that supports Jennifer's case.
Jennifer says: Decline is due to Videorama
Brad says: No, that's not true, something else is responsible
To weaken Brad's claim, we almost have to reaffirm that the decline is due to Videorama. We just need a more clear way to explain it.
Jennifer's claim can still be valid if we fill in some of the holes. Brad pointed out one of the holes, which was that Videorama only sold 4000 videos and there's a gap in order to reach the 10,000 decline in video rentals.
Now what can explain the gap?
(E) does the best job because if for every 1 video sold that cannibalized 2, 3 or more video rentals, than the cannibalization effect could be far in excess of 10,000 video rentals.
(A) also helps explain the gap but it's not strong enough. If Videorama rented out more than it sold, it's possible that it sold 4,000 and it rented 5,000. Together, that's 9,000 and so there's still 1,000 that cannot be explained. On the other hand, it's possible that 4,000 was sold but 6,000 was rented. That would reach the 10,000 and this would weaken Brad's argument. However, since it goes both ways it does not definitively weaken the argument...and would only be a "weak" method of weakening the argument.
(B) in a similar manner is "weak" and also is not relevant because it places the explanation on something other than Videorama, ie the other two stores, when clearly the argument is referring to Videorama.
