Answer:
B.) The author appeals to the audience’s sense of pathos by calling readers to action and calling their attention to what will ultimately be gained if the call to action is heeded.
C.) The author appeals to the audience’s sense of ethos by providing readers with the perspective of scientists. This adds credibility to the author’s claim that each of us can positively impact the future of national parks.
Step-by-step explanation:
"Ethos" refers to an argument that is based on credibility or evidence to support it. Choice C uses "ethos" by providing evidence in accordance to scientific studies. It makes the writer an expert in the topic that he is talking about because it is backed by facts.
"Pathos" refers to an argument that is based on emotions. By telling the people compelling stories that affected climate change, the readers' attention will be called. It persuades them to do something about the environment. Choice B shows how such persuasion happens.
