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.  

either a donut or a sphere or a pancake or a flat sphere. it depends on where the vertical line is.

if the line goes through the center of the circle and is perpendicular to a diameter containing the center, then you get a flat circle.

if the line and the diameter of a the circle meet in the center of the diameter and at an angle, you get a pancake.

if the line is on the circumference of the circle and is at right angles   to the circle you get a ring.

if the line contains the diameter, you get a sphere.

the the line is parallel to the diameter and touches the circumference, you get a donut.
