I took Oliver to the Marin Headlands with my roommate a few days back . I ' m fairly certain that it 's the first time he 's ever seen the ocean . He went crazy - first he ran from the waves , then he dove into them , then he tried to bite the water , then he picked up a gigantic piece of seaweed bigger than his body and carried it around , then he chased some driftwood , then he barked at a seabird , then he romped in the sand , and then he collapsed in exhaustion because he was cold and wet . We went and warmed ourselves in the car where he proceeded to pass out .

Question: What is one thing we know about Oliver ?
Answer: He 's a canine .None of the above choices .He 's a teen .He 's a child .
