Read the sentence. the coach’s speech during halftime of the championship game provided an impetus for improving his team’s broken morale, allowing them to pick themselves up and get back on the field. which word most accurately describes the meaning of impetus as it is used in this sentence? movement lecture motivation distraction

It’s motivation. Just replace impetus with motivation and it’ll make sense. If you replace it with movement, lecture, or distraction it doesn’t make any sense. A speech can’t provide a lecture, it can’t provide a movement, and a distraction doesn’t help the team like the coach’s speech does therefore the answer is motivation. The coach’s speech gave the team motivation. It makes sense and it helps the team like it says it does in the passage.
