O She is motivating readers by giving them a reason to  learn more about the subject.

Explanation:

The scientific yet humorous book "A Black Hole is not a Hole" written by Carolyn Cinami de Cristofano delves into the concept of black holes. The book also provides answers and information about space and about the black holes and other findings of the concept of the black holes and other space-related questions.

The author raised the question "What is a black hole if it is not a hole?" not because she did not know the answer or anything. But rather than that, she posed this question to motivate the readers to learn more about the black holes and provides a reason to do that. And in providing such motivation, she takes the readers further along the ride in learning in a fun way about the various findings and questions about space that a person may have.  

Thus, the correct answer is the fourth option.

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.
