Final answer:
The pediatrician appeals to ethos and logos when supporting her argument with research-based evidence. Ethos establishes credibility, and logos uses credible information and evidence to explain the situation.
Step-by-step explanation:
The pediatrician appeals to ethos when she uses research-based evidence to support her argument. Ethos is the presentation of a believable, authoritative voice that elicits an audience's trust. By using reliable sources such as a student survey, data from a professional organization, and information from an interview with a mental health counselor, the pediatrician establishes credibility.
The pediatrician appeals to logos as well. Logos is the use of credible information-facts, reasons, examples-that moves toward a sensible and acceptable conclusion. In this case, the pediatrician uses data and credible evidence to explain the current situation and its effects, supporting her sound reasoning for expanded mental health services.
