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? ['The condor as a species will eventually become extinct in the wild.', 'It is almost impossible to eliminate all the environmental threats to the eggs of condors.', 'The most feasible way to save the condor from extinction is to increase egg production.', 'If more condor eggs do not hatch, the condor as a species will not survive in the wild.']
