[EX Q]: Article: On a Friday night in May 2015, Oliver and Lone Kleven heard angry shouts coming from their front lawn. Lone, 68, stepped onto the porch and saw two men in dark clothes struggling with something on the ground--right where she and her grandson had planted a flower bed the weekend before. "Go fight somewhere else!" she shouted, worried her plants would get damaged. At the sound of her voice, the face of a boy appeared from beneath the two men. He looked 13 or 14 or so. "They're trying to kill me!" the boy screamed. Lone ran toward them and, without hesitation, caught the boy's arm, pulling him out. "Leave _ alone!" she shouted. When the men stood up, Lone saw what looked like a sharp object in one man's hand. When she turned back toward the boy, he was moaning in pain and holding his stomach. The attackers began to move in on the boy again when Lone's husband shouted: "Get lost!" The two men walked quickly and quietly across the street and drove off in a dark car. "I have to get to the hospital!" the boy cried. He lifted his shirt, and Lone could see a bloody wound on his stomach. Oliver hugged the trembling boy while Lone caught her cell phone and car keys inside the house. She handed the phone to Oliver. "Call 911," she told him. "I'm going after them." Lone took off but was unable to find the car. The Klevens then learned what had happened. Earlier that night, as the boy waited for his parents to pick him up from the high school across the street from the Klevens' house, two men approached and demanded his wallet. When he refused, one of the men hit him in the face. The boy ran across the street. The men caught up with him, and one hurt him in the back and stomach with a sharp knife. That's when Lone stepped in. The boy's wounds required operations, but he has fully recovered. "He was alone and outnumbered," says Lone. "There was no time to do anything except what I did."
Question: Why did Lone shout at the man at the beginning of the story?
Options: (A) To stop them fighting with each other. (B) To prevent her flowers being ruined. (C) To stop them stealing in the flower bed. (D) To keep the boy from being wounded.

[EX Q]: Article: According to a study by SallieMae, 84 percent of undergraduate students have credit cards, and by the time they are seniors, they have accumulated US $ 4,100 in debt, on top of whatever student loans they may have taken out. Credit cards are the most convenient form of payment, and they are aggressively marketed to college students.Reportedly, a typical college student carries 4.6 credit cards and US $ 3,173 in credit card debt. Credit cards seem to be a fact of life, not just student life. In the long term, using a credit card properly and paying off the balance can help establish a card history and increase your credit score, which will _ when you need an important loan, for a house or car, for example.Your credit score can affect even unrelated things like insurance rates.Credit cards also offer more protection for users than debit cards .Under federal law, the credit card holder is only responsible for the first US $ 50in fraudulent purchases in cases of theft or loss.However, debit card users are responsible for the first US $ 500. SallieMae found some good news in the fact that two thirds of students had discussed credit issues with their parents, but 84 percent said they needed more information.Those who didn't get any guidance were more likely to be surprised when they found out how much they owed. While credit cards offer the easiest access to money, they make it easy to live outside your means.Less than a fifth of students surveyed paid off their balance every month, and carrying a balance brings finance charges, sometimes at a very high interest rates. SallieMae found that almost 40 percent of students chose their first credit card based on direct mail, which is probably why students get credit card offers in the mail. But when the credit card offers flow in, be sure that you read the fine print.Offers of low or no interest rates can disappear, leaving you a debt that climbs beyond your ability to pay it off.
Question: According to SallieMae, what is the possible reason why students get so many credit card offers in the mail?
Options: (A) Many students' first credit card is based on direct mail. (B) it costs the banks little to mail out credit cards. (C) Students don't like to go to the bank to open a credit card account. (D) Banks have no other way to let students use their credit cards.
