The gray squirrel, introduced into local woodlands ten years

Question

The gray squirrel, introduced into local woodlands ten years ago, threatens the indigenous population of an endangered owl species, because the squirrelsâ€™ habitual stripping of tree bark destroys the trees in which the owls nest. Some local officials have advocated setting out poison for the gray squirrels. The officials argue that this measure, while eliminating the squirrels, would pose no threat to the owl population, since the poison would be placed in containers accessible only to squirrels and other rodents. 

Which one of the following, if true, most calls into question the officialsâ€™ argument?
 
(A) One of the species whose members are likely to eat the poison is the red squirrel, a species on which owls do not prey. 
(B) The owls whose nesting sites are currently being destroyed by the gray squirrels feed primarily on rodents. 
(C) No indigenous population of any other bind species apart from the endangered owls is threatened by the gray squirrels. 
(D) The owls that tare threatened build their nests in the tops of trees, but the gray squirrels strip away back from the trunks. 
(E) The officialsâ€™ plan entails adding the poison to food sources that are usually eaten by rodents but not by other animals.

B for me..
If owls are praying on rodents, and as per premises if rodents too can get poisoned then it weakens the argument

It is B.

I would like to see the OE about D, which is attacking the evidence directly. Is it sometimes OK to attack evidence directly in GMAT?

shahnandan · Answer

Well, the assumption here is that the population of the owls are going to be affected if the rodents are eliminated.

We need something which attacks this assumption and B does it .
