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.

You might be able to guess what this was, but for scientists, the best answer came as a shock. In 1994 telescopic evidence confirmed the amazing cause: a supermassive black hole, with the mass not of one imploded star, not of two, but of millions—maybe even billions.

In the excerpt, the author makes a connection between the discovery of quasars and radio galaxies and

the invention of the radio telescope.

the scientist who mapped radio waves.

the identification of the Milky Way.

the confirmation of a supermassive black hole.

The ancient greek poet. homer, is credited with writing the odyssey. however, scholars still debate whether homer wrote the entire epic. what is the main reason for this uncertainty? o some sections of the epic are written in different poetic styles and forms. most ancient greeks could not read or write, so the epic was first written in latin ob och storytellers repeated the epic aloud for centuries before it was ever written down. od the epic was a fictional account, so the identity of its author may have been fictionalized as well.
