Read the excerpt from Neil deGrasse Tyson’s “Death by Black Hole.”As far as I know, nobody has ever been eaten by a black hole, but there is compelling evidence to suggest that black holes in the universe routinely dine upon wayward stars and unsuspecting gas clouds. As a cloud approaches a black hole, it hardly ever falls straight in. Unlike your choreographed feet-first fall, a gas cloud is typically drawn into orbit before it spirals to its destruction. The parts of the cloud that are closer to the black hole will orbit faster than the parts that are farther away. Known as differential rotation, this simple shearing can have extraordinary astrophysical consequences. As the cloud layers spiral closer to the event horizon they heat up, from internal friction, to upwards of a million degrees— much hotter than any known star. The gas glows blue-hot as it becomes a copious source of ultraviolet and x-ray energy. What started as an isolated, invisible black hole (minding its own business) has now become an invisible black hole encircled by a gaseous speedway, ablaze with high-energy radiation.Which of the following suggestions would be most beneficial for a reader in order to gain a better understanding of the information presented in this excerpt?
Which statement best explains how Neil deGrasse Tyson’s “Death by Black Hole” and Billy Collins’s “Man Listening to Disc” present differing views about the universe?
Read a paragraph from a presentation.Most of you probably are fans of typical American sports such as baseball and basketball. However, I urge you to consider watching and participating in sports that are popular in other nations. Most of us are familiar with soccer. However, few of us realize that it is the most popular sport in the world. You’ve all experienced Super Bowl Sunday madness, but that is nothing compared to the international frenzy that sweeps across our planet every four years when soccer’s World Cup occurs. Watching the games of the World Cup can be a fun way to connect with other sports fans around the globe.Based on the paragraph, who is the target audience for this presentation?
Read this excerpt from Extremely Loud and Incredibly Close.I started inventing things, and then I couldn’t stop, like beavers, which I know about. People think they cut down trees so they can build dams, but in reality it’s because their teeth never stop growing, and if they didn’t constantly file them down by cutting through all of those trees, their teeth would start to grow into their own faces, which would kill them. That’s how my brain was. Which line best reflects the ambiguity of this excerpt?
Which of the following ideas is discussed in both Neil deGrasse Tyson’s “Death by Black Hole” and in Billy Collins’s “Man Listening to Disc”?
