Answer:
Ethical
Step-by-step explanation:
An appeal to ethos refers to an appeal to credibility. This means that an author tries to gather support for his or her argument based on the fact that he or she is knowledgeable in the subject. In this example, Wollstonecraft wants to demonstrate that she has authority to talk about the subject because of her knowledge. She proves this by talking about the many different books she has read about education.
