Critical Reasoning

raviagni wrote:A certain type of insect trap uses a scented lure to attract rose beetles into a plastic bag from which it is difficult for them to escape. If several of these traps are installed in a backyard garden, the number of rose beetles in the garden will be greatly reduced. If only one trap is installed, however, the number of rose beetles in the garden will actually increase.

Which one of the following, if true, most helps to resolve the apparent discrepancy?
(A) The scent of a single trap�s lure usually cannot be detected throughout a backyard garden by rose beetles.
(B) Several traps are better able to catch a large number of rose beetles than is one trap alone, since any rose beetles that evade one trap are likely to encounter another trap if there are several traps in the garden.
(C) When there are several traps in a garden, they each capture fewer rose beetles than any single trap would if it were the only trap in the garden.
(D) The presence of any traps in a backyard garden will attract more rose beetles than one trap can catch, but several traps will not attract significantly more rose beetles to a garden than one trap will.
(E) When there is only one trap in the garden, the plastic bag quickly becomes filled to capacity, allowing some rose beetles to escape.

i am stuck between D and E and i chose E because i dunot understand D so much.
on the one hand it says the presense of any traps will attract more rose bettles, it means the more trap the more roses beetles and on the other hands it states several traps will not attract more rose beetles to the garden than one tra[. is it not right that 2 sentences in that aurgument opposite each other?
