Read the excerpt from Kennedy’s inaugural address. To those people in the huts and villages of half the globe struggling to break the bonds of mass misery, we pledge our best efforts to help them help themselves, for whatever period is required—not because the communists may be doing it, not because we seek their votes, but because it is right. If a free society cannot help the many who are poor, it cannot save the few who are rich.

What is the main type of appeal that Kennedy uses in this excerpt?

an ethical appeal to demand that the communists help around the globe
an emotional appeal to emphasize the United States' commitment to justice
a logical appeal to help people in poverty since there is no need to help the rich
a logical appeal to explain why people around the globe cannot vote for a better life
