What can be inferred from these sentences? caretakers cannot release baby chimpanzees into the forest immediately after they are rescued. the babies are totally dependent upon their mothers for care and emotional support during the first several years of their lives. once rescued from the wild, chimpanzees can never be sent back to the wild. baby chimpanzees are left with their mothers at rescue camps instead of being released into the wild. baby chimpanzees can only be released into the forest with their mothers, as they cannot survive without their mothers.

From all these sentences i would infer that the baby chimpanzees are fed by the caretakers and stay in care forever, however:

so the options would be

once rescued from the wild, chimpanzees can never be sent back to the wild. (i don't think this is true, this cannot be implied from the
baby chimpanzees are left with their mothers at rescue camps instead of being released into the wild.
- i think that this is the correct implication. if i understand correctly that this is one of the options: babies are vulnerable when they're young, so they cannot be released immediately.
baby chimpanzees can only be released into the forest with their mothers, as they cannot survive without their mothers.
