It has 2 be option D.
Reason:
option 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.
in the above-
any traps- means one or more. so even 1 trap is enough to attract more rose beetles.
assume that several traps were there .. option D in the second part of the sentence says it will not be able to lure more rose beetles but certainly can catch more rose beetles than a single trap can.this is supported by the passage.look below to see what the passage says..
Passage says : If several of these traps are installed in a backyard garden, the number of rose beetles in the garden will be greatly reduced .
Ultimately the point is, If several traps where there they will lure the same no of beetles as 1 trap but the no of beetles being caught by several trap will be more. How ever if 1 trap was installed it wil lure more beetles but wil be able to catch fewer than several traps installed.
Option D says that one trap installed is just going 2 increase the no of beetles.
I hope i was not too confusing.
and thats the OA ?

IMO D ....
None of the other options is good enough to replace D.. so by POE D...

Please post the OA.
Original post was on July 6th. Today is July 17th.
Just a suggestion - This is the reason why OA needs to be posted with the question and with the spoiler on so that good questions like this one are answered, and doesn't get lost in the shuffle of unanswered questions. This contributes more to everyone's learning experience.

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.

It explains both sides of the argument. E does only half.

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?

I too answered E but seems that E is wrong..
E says that bag becomes full early...
So lets say, there are 5 insects present n capacity is to catch 2 insects..
So, when the bag becomes over capacity by catching 5 insects, then 3 escape... But where is the increase in number of insects....
D says that more will be attracted, increasing the number of insects...

Hello, everyone - sorry for the late check-in on this (I was on vacation when I received a few PMs to chime in, and didn't get those messages until today).
D is the only answer choice that is consistent with both parts of the discrepancy:
1) Several traps will greatly reduce the overall number of beetles
BUT
2) Only one trap will actually INCREASE the number of beetles
Choice E demonstrates why one trap alone may not have a proportional impact to multiple traps (some beetles will escape, so the presence of multiple traps will do a much better job than one alone), but it doesn't address that INCREASE in the overall number of beetles.
Choice D does that, by noting that the first part of the trap is to draw beetles, and the second is to trap them. With only one trap, it will draw many more than it can catch, increasing the number of beetles and only catching some of them. If other traps won't increase the number of beetles, then they'll simply catch without drawing more, so that's why multiple traps will decrease the number of beetles, but one trap alone will actually increase that number.
This question is a great example of the methodology for Strengthen/Weaken/Explain-the-Paradox questions - the specifics of the conclusion (or paradox) are paramount - here, it's crucial that the correct answer doesn't merely explain why one trap may have limited effectiveness...we need to explain that overall INCREASE in the number of beetles,and only D does that.
