read the excerpt from neil degrasse tyson’s “death by black hole.”
black holes are regions of space where the gravity is so high that the fabric of space and time has curved
back on itself, taking the exit doors with it. another way to look at the dilemma: the speed required to
escape a black hole is greater than the speed of light itself. . . . light travels at exactly 299,792,458 meters per
second in a vacuum and is the fastest stuff in the universe. if light cannot escape, then neither can you,
which is why, of course, we call these things black holes.
which of the following features would best enhance the reader’s understanding of this excerpt?
○ a photograph of a black hole
○ a demonstration of the speed of light
○ an interactive animation of a black hole
○ a definition of the term black hole

Explanation:

The excerpt explains the concept of black holes related to gravity, space - time curvature, and the speed of light. An interactive animation of a black hole can visually represent the complex ideas like space - time curving and how light behaves near a black hole, which would enhance the reader's understanding. A photograph of a black hole might not show the dynamic and theoretical aspects described. A demonstration of the speed of light is not directly related to explaining black holes as the excerpt is about black holes' properties. A definition of a black hole is already somewhat provided in the excerpt's description.

Answer:

an interactive animation of a black hole
