Which type of information processing allows the herd of elephants to make this choice? The model below represents the path that a herd of elephants would take if given the choice when encountering the scents of two different tribes.

• Use memories stored in the brain to recall the Kamba tribe, which has hunted them in the past.

• Use memories stored in the brain to recall the Maasai tribe, which has hunted them in the past.

• Use memories stored in the trunk to recall the Kamba tribe, which has hunted them in the past.

• Use memories stored in the trunk to recall the Maasai tribe, which has hunted them in the past.
