After reading the paragraph below, answer the questions that follow.
California condors, large, predatory birds that were previously on the edge of extinction, have benefited from a program that raises birds in captivity and then releases them into the wild. The reintroduction program, however, is having variable success.
Which information provides the best evidence to help develop a hypothesis about what is causing the difficulties faced by a coastal condor population?
◦ Air currents along the coast are stronger, allowing coastal condors to cover more area in their search for prey.
◦ Hatching success in birds farther from the coast was greater than that in birds along the coast.
◦ California bans ammunition containing lead (Pb) to prevent lead ingestion by condors feeding on carcasses of animals shot by hunters but not retrieved.
◦ Sea lions, food for condors along the coast, live near an old dumping ground for a chemical manufacturing plant and have a significant amount of DDT in their blubber.
