How so these excerpts work together to develop a central idea?

B. An emotional appeal to emphasize the United States' commitment to justice. :)

The correct option is number 2: An emotional appeal to emphasize the United States’ commitment to justice.

Explanation:

The first option is not correct because the excerpt is not demanding the communist to help others. The third option is not accurate because it does not say that the rich cannot be helped. He says that if society cannot help the poor, they cannot save the rich. The fourth option is not right because the author is not explaining why the poor cannot vote. The second option is correct since he is saying that they need to help because it is a right. This illustrates the commitment of the United States to justice.
