15.   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.

(B) The best way to save the condor from extinction is to breed it in captivity.

(C) It is almost impossible to eliminate all the environmental threats to the eggs of condors.

(D) If more condor eggs do not hatch, the condor as a species will not survive in the wild.（D）

(E) The most feasible way to save the condor from extinction is to increase egg production.

想請問答案為什麼是D??  為什麼不是C??  謝謝

(C) It is almost impossible to eliminate all the environmental threats to the eggs of condors.作用类似于前提（当然ALL THE改为KEY就完全可以作为前提了，而前提是最弱的加强）；

(D) If more condor eggs do not hatch, the condor as a species will not survive in the wild.是典型的加强。
