Answer:
- Ethos, an appeal based on the speaker's character.
Step-by-step explanation:
Ethos is illustrated as the persuasive appeals that attempt to persuade the audience ethically by establishing the credibility of the author. It is described as one of the 'three modes of persuasion'(as stated by Aristotle), the other two being logos(logical appeal) and pathos(emotional appeal).
In the given sentence, the speaker employs 'ethos' as he/she attempts to persuade the audience by invoking authority 'as a president of the Student Council for two years' that exemplifies the appeal based on 'speaker's character' or 'credibility'. Thus, the speaker attempts to convince the audience ethically to accept his idea of 'establishing a better system for spending funds'. Therefore, 'ethos' is the correct answer.
