Scientists have often debated about whether animals have the capacity for
human-like emotional connection. One possible example of such connection is
elephants that have been observed apparently paying homage to their dead. In a
study conducted in Kenya, researchers placed three objects—a piece of wood, a
piece of elephant ivory, and an elephant skull—a short distance from a herd. The
elephants showed a marked preference for the ivory and the skull. They repeated
the experiment with the skulls of an elephant and two other animals. As they
predicted, the elephants showed a preference for the elephant skull.
Which generalization can be made based on the passage?
1;Elephant responses to different objects indicate a human-like emotional connection to other elephants.
2;All animals have emotional responses to the deaths of others of their species.
3;Elephants respond to the remains of other elephants in an apparently emotional fashion.
