Which excerpt from neil degrasse tyson’s “death by black hole” best provides evidence that escape from a black hole is impossible? . . 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. 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. 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. 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.

In the real world, feldman learned to settle for less than 95 percent. he came to consider a company “honest” if its payment rate was above 90 percent. he considered a rate between 80 and 90 percent “annoying but tolerable.” if a company habitually paid below 80 percent, feldman might post a hectoring note, like this one: the cost of bagels has gone up dramatically since the beginning of the year. unfortunately, the number of bagels that disappear without being paid for has also gone up. don’t let that continue. i don’t imagine that you would teach your children to cheat, so why do it yourselves? the excerpt serves as which type of support for the authors’ argument? a claim an example a conclusion a counterclaim
