This sentence is from the passage. "It keeps us and all of the objects around us fixed to the
earth's surface; it keeps the air we breathe from
escaping to outer space; it keeps the moon in orbit
around the earth and it keeps the earth bound in orbit
around the sun." (Paragraph 2)
How does the sentence help develop an important idea
about gravity?

I assume that you were given several options. You haven't provided them and they are unavailable online, but I will try to help you anyway.

The given sentence tells us about how important gravity is. The tool used to emphasize its importance is parallelism.

Parallelism (also referred to as parallel structure or parallel construction) refers to the repetition of the same or similar grammatical structure in clauses and sentences. Its purpose is to create a rhythm, make a comparison, emphasize, or elaborate on an idea.

The given sentence consists of four clauses that begin the same way - with the phrase it keeps. This phrase actually represents the subject and the predicate. Every time, it's followed by the object (in this case, the recipient of the action expressed by the verb keeps). The purpose of parallelism here is to emphasize the importance of gravity.

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
