user: The address I had been given was a flophouse called Casa Salvador in the scummy side of downtown, the part where the city's redevelopment (read: "gentrification") efforts hadn't yet managed to drive out the sundry undesirable elements. I walked inside past the front lobby. I could tell the desk manager wanted to hassle me, but he was too busy arguing with a middle-aged peroxide-blonde woman in a leopard-print top. Her skin was leathery and weather beaten, and I guessed she was the type who was actually a good ten years younger than she looked. I made my way up the narrow staircase that smelled of urine and bleach, going all the way to the third floor. I continued down the dimly lit hallway, past a series of closed doors that muffled the sounds of women faking moans of pleasure. Room 313 was down at the far end of the hall, and its door was already slightly ajar. I knocked anyways, but there was no answer. Pushing the door open just enough to poke my head in, I called, "Hello? Is anybody in there?" There was no response, so I went in and felt along the wall for the light switch. A single weak bulb came on, lighting up the tiny, sparse room with a dim yellow glow. The room was about 8 feet by 8 feet, and the only furniture was a dingy, unmade bed and a metal foot locker. There were no windows, no closet, and no bathroom. As I stepped all the way in, I noticed a wooden baseball bat propped up beside the door. My watch said 6:20 - twenty minutes late for the interview. I sat on the edge of the bed to wait, hoping that maybe my contact had just stepped out momentarily. After a few minutes, a phone started ringing out in the hallway. I let it ring six times with no one answering before I decided to get it - partly in the off chance it was my contact, but mostly out of morbid curiosity as to what kind of business someone would have calling this dump. According to the above context, choose the correct option to answer the following question. Question: How long was he in the front lobby? Options:  A. A few seconds.  B. 20 Minutes.  C. not enough information  D. A few minutes.

SEOUL — The U.S. and South Korea remain united in pursing a diplomatic solution to end the North Korean nuclear threat, but their national security priorities may differ over what would be the role of the U.S. military in Korea after a denuclearization deal is reached. “That is going to be the moment of truth, so to speak, when the United States and South Korea will have to agree on what kind of security alliance we want to maintain moving forword,” said Go Myong-Hyun, a North Korea analyst at the Asan Institute for Policy Studies in Seoul. U.S. President Donald Trump on Friday revived the June 12 Singapore summit with North Korean leader Kim Jong Un, eight days after canceling it. Trump said he was convinced of Kim’s commitment to denuclearization by the renewed diplomatic talks that included a visit to Washington by Kim Yong Chol, the North’s former intelligence chief, who carried a letter from the North Korean leader. South Korean President Moon Jae-in has been influential in facilitating the U.S.-North Korea summit, in getting Kim to agree to the broad goal of denuclearization, and in urging Trump to stay committed to the diplomatic process to resolve differences with North Korea. President Trump seems to be leaning now towards Moon’s approach versus the more confrontational stance advocated by some of his security team in demanding that North Korea unilaterally and completely disarm before any concessions are granted. Friday Trump downplayed expectations for a major breakthrough at the summit, saying it will be the beginning of a process. He also backed away from his “maximum pressure” approach that stressed tough sanctions and the threat of military force, focusing instead on brokering an agreement to end the North’s nuclear program for economic aid and security guarantees that could include a peace treaty to replace the armistice that ended the Korean War in 1953. South Korean officials said there is possibility that Moon may join Trump in Singapore to help negotiate a nuclear deal with Kim, as the...

Options:  A. after 2 days of cancelling it  B. after 8 days of cancelling it  C. after 3 days of cancelling it  D. not enough information

Question: Patch's mother was named Silver, because high summer sun made her fur shine that colour. She had a marvellous drey high up a spruce tree, carved out long ago by a woodpecker, and since extended into a two-chambered home full of bright things. The journey along the sky-road to her drey did not take long. When Patch looked inside, he saw a hundred colours glittering in the sunlight, shining from bits of metal and glass set into Silver's walls and floor. But his mother was not there. He could tell by the faintness of her smell that no squirrel had been here in some time. There were two faint traces of scent, several days old; that of Silver, and that of another squirrel, a musky scent that Patch did not recognize. A scent that made his tail stiffen as if danger was near. Patch stared into his mother's empty drey for a moment. It wasn't normal for a squirrel to abandon her drey for days, not in the middle of winter. And he hadn't seen Silver for three days. Not since all the acorns had disappeared from the earth. Patch ran back to his own tree, and then to the maple tree next door, to his brother Tuft's drey. He ran very fast. He was hungrier than ever, and he was beginning to be very worried. He was relieved when he looked into Tuft's drey and found it occupied. Tuft himself was not present, but Brighteyes was, and their babies, and it was clear from the smells that Tuft had only just departed. "Hello, Patch," Brighteyes said weakly. "Would you like to come in?" Patch entered. Brighteyes was curled up with her babies in the drey's deepest, warmest corner. The last time Patch had visited, a week ago, this had been a den of noise and chaos, with all Brighteyes' four babies running and jumping and playfighting. Today they lay weakly beside Brighteyes, and the once-shining eyes from which their mother had taken her name were dim and clouded. According to the above context, choose the correct option to answer the following question. Question: Who abandoned their drey? Options:  A. Brighteyes  B. not enough information  C. Patch  D. Patch's mother
