Read the excerpt from “Death by Black Hole.”If you were made of rubber then you would just stretch in response. But humans are composed of other materials such as bones and muscles and organs. Your body would stay whole until the instant the tidal force exceeded your body’s molecular bonds. (If the Inquisition had access to black holes, this, instead of the rack, would surely have become the stretching device of choice.)Which sentence from the excerpt supports the idea that falling into a black hole would be a violent death?

A

B
But humans are composed of other materials such as bones and muscles and organs.
C
Your body would stay whole until the instant the tidal force exceeded your body’s molecular bonds.
D

Read the excerpt from Death by Black Hole.Albert Einstein’s general theory of relativity, published in 1916, provides the insight to understand the bizarre structure of space and time in a high-gravity environment. Later research by the American physicist John A. Wheeler, and others, helped to formulate a vocabulary as well as the mathematical tools to describe and predict what a black hole will do to its surroundings.Read the excerpt from “Man Listening to Disc.”And I bow deeply to Thelonious Monkfor figuring out a wayto motorize—or whatever—his huge pianoso he could be with us today.The central idea that both texts share is

A
connections between math and music
B
references to musicians the narrators admire
C
predictions about the future of mankind
D
credit to people who have inspired the authors

Read the excerpt from Neil deGrasse Tyson’s “Death by Black Hole.”All parts of your body are moving toward the same spot—the black hole’s center. So while you’re getting ripped apart head to toe, you will also extrude through the fabric of space and time, like toothpaste squeezed through a tube.Read the excerpt from Billy Collins’s “Man Listening to Disc.”This is not bad—ambling along 44th Streetwith Sonny Rollins for company,his music flowing through the soft calipersof these earphones,Which of the following ideas is presented in both excerpts?

A
humanity as a small piece in a very large universe
B
the human body is being moved along by an outside force
C
individuals finding and accepting their place in the world
D
one individual becoming the center of a vast universe

Which excerpt from Neil deGrasse Tyson’s “Death by Black Hole” best provides evidence that escape from a black hole is impossible?

A
. . . 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.
B
But if the black hole were 6,000 feet across, then the same man’s feet would be only one-tenth of 1 percent closer to the center than his head, and the difference in gravity—the tidal force—would be correspondingly small.
C
Meanwhile, the stuff within the event horizon has collapsed to an infinitesimal point at the black hole’s center. So black holes are not so much deadly objects as they are deadly regions of space.
D
If you stumbled upon a black hole and found yourself falling feet-first toward its center, then as you got closer, the black hole’s force of gravity would grow astronomically.

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
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

to the woman in the white sweater,the man in the tan raincoat and the heavy glasses,who mistake themselves for the center of the universe— all I can say is watch your step
C
because the five of us, instruments and all,are about to angle overto the south side of the streetand then, in our own tightly knit way,
D
