The correct answer to this open question is the following.
The author of this brochure uses appeals to ethos and pathos to influence the audience in that section in the following way.
The author uses Ethos when he writes that "Parks across the nation are conducting Climate-Friendly Park workshop co-sponsored by the Environmental Protection Agency, to evaluate energy usage and to improve park operations." Let's remember that Ethos is the appeal to convince an audience using the experience or credibility of the speaker. In this case, the author is using the credibility of a federal government agency to back the workshop and its purpose.
The author uses Pathos when he writes that "Many times, during our nation's history, citizens have confronted difficult circumstances and found creative solutions. Pathos is the appeal to convince an audience using the emotion to convince them. So the author expresses this way to make people feel they have lived difficult moments but the American people are so grand, that they always find the right thing to do under difficult moments.
While D is also correct, A is most correct. The US government cannot offer public services and other tax fueled services if everyone chooses not to pay.
