Question

which statement primarily appeals to ethos to support the position that breakfast is the most important meal of the day? students who routinely skip breakfast suffer academically; they have great difficulty concentrating in class and consequently perform poorly in school. because the brain requires a certain amount of glucose in order to function optimally, it is important to eat a healthy breakfast at the start of your day. as an experienced marathon runner, i know how important it is to eat a well - balanced breakfast before a race.

Explanation:

Ethos appeals to credibility or authority. The first two statements use logical evidence (academic performance, brain glucose needs) which is logos. The third statement relies on the speaker's identity as an experienced marathon runner, establishing personal credibility to support the claim about breakfast's importance.

Answer:

As an experienced marathon runner, I know how important it is to eat a well-balanced breakfast before a race.
