根据下列短文，回答题。Cousteau RememberedJacques-Ives Cousteau died in Paris on 26 June, 1997 at the age of 87. His influence is great. Scientists respected his creative engineering; engineers praised his science. Cousteau, who claimed to be neither scientist nor engineer, contributed significantly to both disciplines—and to many more.
Throughout his adventure-filled life, Cousteau challenged definitions. Yes, he was a captain in the French Navy, and early on, a filmmaker and natural storyteller. Later, he became a famous ocean explorer, designer of underwater equipment, expedition leader, author, speaker, businessman, environmentalist, teacher and leader of an influential organization (the Cousteau Society).
All who care about the sea—and even those who don't think much about the ocean one way or another—owe Cousteau a tremendous debt. The knowledge gained as a consequence of his direct contributions, and the strong impact he had on others, have transformed the way the world thinks about the sea. His stories of encounters with sharks and other fish inspired many to go see themselves. Cousteau pioneered ventures in underwater living in the 1960's: sub-sea labs where scientists submerged for days or weeks－the underwater labs similar to Skylab or the space station. His films and television programmes won two Academy Rewards, three Emnies, and the hearts and minds of viewers worldwide for decades.
Showered with honours, Cousteau remarked recently that he thought his most important accomplishment was to make people aware of－and care about－the ocean: Thanks to him, we grew concerned about our growing population and the consequences of over fishing and ocean pollution that threaten the health of the sea, and we were inspired to do something to improve the way things are done.
We shared the sad feeling with Cousteau when Simone, his wife and partner for many years, died and when his son Phillippe was killed in a plane crash. We shared his joy when Jean-Michel, his eldest son, became an explorer and a spokesman for the sea in his own right. We were happy for Cousteau when he began a new family with his second wife, Fracine. And now that his voice of the ocean is silenced, we feel very sad.According to the passage, Cousteau's influence is great because he __________. A．A was both a scientist and an engineer
B．B invented Skylab
C．C made contributions to science and engineering
D．D was a captain in the French Navy
