Context: Alona's persistent knocking at the door of room 412 went unanswered for three minutes as she nervously shuffled her feet. Her book bag was super-saturated with textbooks, notebooks, schedules, rough drafts, and various other forms of academic paraphernalia. It was getting heavier. She continued to knock, even though there had as yet been no answer, because the note card tacked to the right of the door indicated that these indeed were Prof. Turgy K. Sigger's office hours. She could see the light under the door and thought she had heard a groan. Just before she decided to give up, slow feet approached from the opposite side, then silence; with a dramatic turn of the knob, the door swung open. "Was this trip really necessary?" asked Prof. Sigger, blinking and brushing his oily, graying hair back into place. "These are your office hours," Alona replied. She nervously smiled, feeling the corners of her mouth twitch. Somewhere in the darkened hall, a janitor coughed. "All right," conceded Prof. Sigger. "Come in." The carpet was smothered by leaning towers of textbooks. Papers lined the left side of the desk, above which was a small note card which read "To Be Graded." On the right side, the oak finish gleamed of the mid-morning light piercing the Venetian blinds. "You've come about your final project," Prof. Sigger stated. "It's only mid-term," Alona reminded him. "Oh yes, yes," continued Prof. Sigger, without conscious embarrassment. "Mid-term grade. I think I have it here. Somewhere." His hands disappeared into the left side of his desk. "You told the class that we would get a C if we maintained that Coca-Cola isn't a crypto-fascist conspiracy." "Oh yes," said Prof. Sigger. "We were discussing social issues, as I remember. I was quoting Marx and some little idiot brought up Rush Limbaugh." "That was me," Alona muttered. Question: Why is Alona at Prof. Sigger's office? Options: A. to discuss her final project B. to discuss her mid-term grade C. to discuss social issues D. not enough information

Read the following context and choose the correct option to answer the question. Context: SEOUL North Korea shut down its Punggye-ri nuclear test site on Thursday to demonstrate its commitment to denuclearization in advance of the planned U.S.-North Korea summit. The development came hours before President Donald Trump called off the highly anticipated meeting. The South Korean government welcomed the North's unilateral nuclear concession to help facilitate a broader agreement with the United States to completely end its nuclear weapons program in exchange for ending punishing sanctions and security guarantees. "We are hoping that this action will become the opportunity for complete denuclearization in the future," South Korea Foreign Ministry spokesman Noh Kyu-duk said. However, while the closure of the nuclear test complex is a significant symbolic gesture, analysts are skeptical it will seriously inhibit the Kim Jong Un government's ability to carry out further nuclear tests in the future. "That renders the test site unusable, but not forever and it's not like North Korea has a shortage of mountains or people to make new tunnels," said Jeffrey Lewis, the director of the East Asia Nonproliferation Program at the Middlebury Institute of International Studies in California, during an interview with Vice News. North Korea conducted all six of its nuclear tests at the Punggye-ri underground site that includes at least two extensive tunnel systems, according the 38 North website that monitors the North's nuclear activities. Each nuclear test conducted at the site was progressively more powerful, with the first bomb detonated in 2006 producing an estimated 1-2 kiloton yield, much less powerful than the 16-kiloton bomb the United States used on Hiroshima during World War II, and the last test in 2017 producing close to a 250-kiloton yield. There were reports that the last nuclear test in September of 2017 triggered a tunnel collapse rendering the site unusable, but analysts say there were still two other tunnels that could be used for future tests. Earlier this year North Korean leader Kim Jong Un... Question: Why did North Korea shut down its Punggye-ri test site? Options: A. not enough information B. For the U.S.-North Korea summit C. To facilitate a broader agreement with the US to end its nuclear weapons program. D. As a demonstration.

Read the following context and choose the correct option to answer the question. Context: I was one of the best fingerprint examiners in the world. I could do things the FBI thought impossible. I could memorize fingerprints. The nearby agencies, including local offices of federal agencies that had their own labs, came to me for help. One day in a trial a new-hatched defence attorney tried to make me seem neglectful because I hadn't sent the prints from the crime scene to the FBI for verification. The FBI will not look at prints that have already been identified locally. I tried to get that across to him. Finally I said, "Sir, you don't understand. I don't ask the FBI for help. The FBI asks me for help." The courtroom went dead silent. The lawyer choked a bit and looked frantically at the judge, who knew me quite well. The judge slowly nodded. The lawyer choked a few more times, said, "No further questions," and returned to his seat. I was the only person in the five-state area in which the silver burglar was hitting who got him on fingerprint evidence. He never left fingerprint evidence . . . except when he did. Every other police agency quit looking, because his MO was unmistakable. We didn't. A detective got prints from a bamboo tree he had used to climb in a window, and I got several prints from items he had handled inside the house. After the trial he was being led back to the jail and I was walking down the hall. He stopped and said, "I want to talk to that lady." The bailiff told him he couldn't talk to the witness, but I said I wanted to hear what he had to say. He said, "Lady, you're the smartest cop I ever saw, and I hope to God I never see you again." I think that was the best compliment I ever got. I have other accomplishments. But I consider my police work the most important. Question: The burglar talked to the author: Options: A. after the trial B. during the trial C. not enough information D. before the trial
