Question

Some animals, such as dolphins, dogs, and African grey parrots, seem to exhibit cognitive functions typically associated with higher-order primates such as chimpanzees, gorillas, and humans. Some parrots, for example, have vocabularies of hundreds of words that they can string together in a comprehensible syntax. This clearly shows that humans and primates are not the only animals capable of using language to communicate. One parrot, named Alex, has been known to ask to be petted or kissed and will exhibit aggression if the gesture offered is not the specific one requested.Which of the following, if true, would most strengthen the conclusion above?

• A. Dolphins can be trained to assist divers in ocean rescues.
• B. Gorillas in captivity often learn hand signals for food and water.
• C. Dogs are capable of sensing their owners' moods and often exhibit concern if they sense sadness.
• D. Chimpanzees can memorize long sequences of key punches on machines that dispense food.
• E. Alex does not exhibit aggression when offered a gesture that he specifically requested.

Answer 1

The correct option is E Alex does not exhibit aggression when offered a gesture that he specifically requested.
