For the condor to survive in the wild, its breeding population must be greatly increased. But because only a few eggs can be produced by a breeding pair over their lifetime, any significant increase in the number of birds depends upon most of these eggs hatching, which is extremely unlikely in the wild due to environmental dangers. One possible way to eliminate the effects of these factors is to breed the birds in captivity and subsequently return them to the wild.
Which one of the following is most strongly supported by the information above?
(A) The condor as a species will eventually become extinct in the wild --
Where does it say this? No where; it just says that it will be difficult for them if they do not have eggs that hatch(B) The best way to save the condor from extinction is to breed it in captivity --
Best way? How do we know this? We do not. (C) It is almost impossible to eliminate all the environmental threats to the eggs of condors --
We have no idea whether it is impossible to eliminate all the environmental factors. Maybe it is just that the wind keeps knocking the eggs off their perch and we can prevent this by putting a barrier around the nest. (D) If more condor eggs do not hatch, the condor as a species will not survive in the wild --
Bingo! This is stated in the the first two sentences. Pop increases needs breeding increase, and breeding increase needs the eggs to hatch. So if the eggs do not hatch, then everything else comes undone. (E) The most feasible way to save the condor from extinction is to increase egg production --
A tricky one. But note the wording. We only talk about those in the wild, and this talks about all condors and the entire population. Further, how do we know what the most feasible way is? We do not talk about this, so it cannot be inferred.
