Read the excerpt from Steven D. Levitt and Stephen J. Dubner’s Freakonomics.Let’s now consider the following statistic, which represents the hundreds of matches in which a 7–7 wrestler faced an 8–6 wrestler on a tournament’s final day: 7–7 WRESTLER’S PREDICTED WIN PERCENTAGE AGAINST 8–6 OPPONENT: 48.77–7 WRESTLER’S ACTUAL WIN PERCENTAGE AGAINST 8–6 OPPONENT: 79.6So the 7–7 wrestler, based on past outcomes, was expected to win just less than half the time. This makes sense; their records in this tournament indicate that the 8–6 wrestler is slightly better. But in actuality, the wrestler on the bubble won almost eight out of ten matches against his 8–6 opponent. Wrestlers on the bubble also do astonishingly well against 9–5 opponents:7–7 WRESTLER’S PREDICTED WIN PERCENTAGE AGAINST 9–5 OPPONENT: 47.27–7 WRESTLER’S ACTUAL WIN PERCENTAGE AGAINST 9–5 OPPONENT: 73.4The authors use the statistics in this excerpt to

Read the excerpt from Freakonomics. Now let’s look at the win-loss percentage between the 7–7 wrestlers and the 8–6 wrestlers the next time they meet, when neither one is on the bubble. In this case, there is no great pressure on the individual match. So you might expect the wrestlers who won their 7–7 matches in the previous tournament to do about as well as they had in earlier matches against these same opponents—that is, winning roughly 50 percent of the time. You certainly wouldn’t expect them to uphold their 80 percent clip. As it turns out, the data show that the 7–7 wrestlers win only 40 percent of the rematches. Eighty percent in one match and 40 percent in the next? How do you make sense of that?Which type of evidence does the authors use in this excerpt to support the claim that some sumo wrestlers will intentionally lose a match?

Read this excerpt from "A Visit from the Goon Squad."Whatever the reason, a swell of approval palpable as rain lifted from the center of the crowd and rolled out toward its edges, where it crashed against buildings and water wall and rolled back at Scotty with redoubled force, lifting him off his stool, onto his feet (the roadies quickly adjusting the microphones), exploding the quavering husk Scotty had appeared to be just moments before and unleashing something strong, charismatic, and fierce. Anyone who was there that day will tell you the concert really started when Scotty stood up.How does the author portray Scotty in this excerpt?

Read this excerpt from "A Visit from the Goon Squad."That’s when he began singing the songs he’d been writing for years underground, songs no one had ever heard, or anything like them—“Eyes in My Head,” “X’s and O’s,” “Who’s Watching Hardest”—ballads of paranoia and disconnection ripped from the chest of a man you knew just by looking had never had a page or a profile or a handle or a handset, who was part of no one’s data, a guy who had lived in the cracks all these years, forgotten and full of rage, in a way that now registered as pure. Untouched.How does the author use satire in this excerpt?

Ladies and gentlemen—” said the ballerina, reading the bulletin. She must have been extraordinarily beautiful, because the mask she wore was hideous. And it was easy to see that she was the strongest and most graceful of all the dancers, for her handicap bags were as big as those worn by two-hundred-pound men.
