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?
Answer
A
a photograph of a black hole
B
a demonstration of the speed of light
C
an interactive animation of a black hole
D
a definition of the term black hole
Explanation
An interactive animation could show how a black hole’s gravity bends space and time and why light cannot escape. That would make the excerpt’s abstract ideas easier to picture. A definition would mostly repeat information already explained in the passage, while a photograph may not show how a black hole affects light or space.
