17. B. “hands-off” approach; expecting employees to get work done but staff can work however they see fit.
In the passage, we see that Bushnell is not a very strict type of manager. He does not try to control his employees, nor is he overly demanding. The passage states that, as long as everyone completed their work, he preferred to leave them alone and work as they see fit.
18. D. her dialogue with Walter.
In “The Secret Life of Walter Mitty,” we are mostly concerned with Walter, and the thoughts that go through his head. Most other characters are only defined through their interactions with him. This is the case of Walter’s wife, who we get to know through her dialogue with Walter.
