Final answer:
The statement that primarily appeals to ethos is the one where the speaker emphasizes their own loyalty as a sports fan and expects the same loyalty from players.
Step-by-step explanation:
The statement that primarily appeals to ethos to support the position that athletes should remain loyal instead of switching teams is: "Like many committed sports fans, I have been loyal to one baseball team for my entire life, and I expect the same type of team loyalty from its players." This statement appeals to ethos by using the speaker's personal experience and credibility as a loyal fan. By emphasizing their own loyalty, the speaker establishes themselves as a credible source and relates to the audience who are also likely sports fans.
