Loggerhead turtles are an endangered species. Aquarium officials presumably know and are concerned about the declining number of wild loggerheads. Nevertheless, aquariums keep loggerheads and display them. These turtles are being kept in captivity and are thus prevented from adding to the population of wild turtles. Each of the following, if true, contributes to an explanation of why aquarium officials keep loggerheads in captivity EXCEPT: ['The population of loggerheads in captivity has declined slightly over the last 20 years.', 'The captive loggerheads are bred, and their offspring are released into the wild, which helps increase the number of wild turtles.', 'The captive loggerheads are used to help educate the public about the needs of wild loggerheads so that the public will take greater care not to harm them.', 'The baby loggerheads in captivity are hatchlings too weak to survive in the wild.']
