What effect does the presentation of information have on the development of the passage?

Susy's and Twain's descriptions of a situation are included, so the reader can examine two viewpoints of the same situation.

Explanation:

The author includes writings from both perspectives.

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.

i think the answer is invented words, rhyming knack, alliteration, and, metaphor.
