Question

which statement primarily appeals to ethos, or character, to support the position that to improve their health, people should stand more and sit less? by now, most people have heard the news that sitting for long periods of time is not just mildly unhealthy but can actually be deadly. numerous studies have shown that simply standing more can improve the overall health of sedentary people. after switching to a standing desk—like many americans, i used to spend most of my day sitting—i experienced subtle but meaningful health benefits: i improved my posture and found i had slightly more energy.

Explanation:

Ethos appeals to the speaker's credibility or personal experience. The third statement uses the speaker's own experience with a standing desk to support the position, establishing credibility through personal anecdote. The first statement is more of a general claim, and the second uses studies (logos, appeal to logic/evidence). So the third statement appeals to ethos.

Answer:

After switching to a standing desk—like many Americans, I used to spend most of my day sitting—I experienced subtle but meaningful health benefits: I improved my posture and found I had slightly more energy.
