Manisha read this excerpt from A Black Hole Is NOT a Hole by Carolyn Cinami DeCristofano.

In fact, every quasar and radio galaxy dot turned out to be energy from the center of an entire galaxy. Astronomers found stars careening around these centers, zooming at previously unheard-of speeds in their orbits. The motion was like an accelerating ice skater pulled around her partner in a tight twirl—or like a fish caught in a superstrong whirlpool. Something extreme had to be in the middle of each of those galaxies.

After reading the excerpt, Manisha made a text-to-self connection. Which example is a text-to-self connection?

Manisha had read an old newspaper article about the discovery of quasars, and that information helped her to understand the excerpt.
Manisha had read a book about Galileo’s contributions to astronomy, and that information gave her background on the subject.
Manisha had seen a fish caught in a whirlpool, and her memory of it helped her understand the author’s description.
Manisha asked her teacher to explain what the author describes in the excerpt because she did not understand it.
