Answer:
The lesson Mr. Bixby tries to teach the narrator is:
D. to keep a cool head in tense situations
Explanation:
In Mark Twain's "A Cub Pilot", Mr. Bixby shakes Samuel's confidence on purpose. He makes Samuel doubt his own abilities, second-guess himself. All Mr. Bixby does is ask Samuel if he is sure he can navigate on his own. Later on, however, he tells Samuel he shouldn't allow him (Mr. Bixby) nor anyone else to shake his faith in himself. He (Samuel) should keep a cool head in tense situations, no matter what it is that people tell him.
