Exercise 6: Establishing Credibility Many teachers take steps to establish credibility (ethos) on the first day of class. For each of the following examples, list which aspect of ethos the teacher is emphasizing for students:
a. A young-looking teacher mentions her graduate degree and teaching experience
twice during the first half-hour of class.
b. An older-looking teacher makes several jokes and talks about playing Angry Birds
and Temple Run over the summer.
c. A teacher who taught at a rival school last year mentions that he’s glad to be at this
school now because it was where his father taught for 20 years.

Which sentences from part 1 of the call of the wild would best serve as evidence of the theme "sometimes survival depends on knowing when not to fight"? buck had accepted the rope with quiet dignity. to be sure, it was an unwonted performance: but he had learned to trust in men he knew, and to give them credit for a wisdom that outreached his own. he had merely intimated his displeasure, in his pride believing that to intimate was to command. but to his surprise the rope tightened around his neck, shutting off his breath. he saw, once for all, that he stood no chance against a man with a club. he had learned the lesson, and in all his after life he never forgot it. that had given them an unfair advantage; but now that it was off, he would show them. they would never get another rope around his neck.
