Q: I'm taking a test and have to guess the right answer to the question after the article. Article: The Danish capital is a year-round destination. Here are some of the city's best annual events. Roskilde Festival (July) The Danes love the outdoors and they love rock music; the Roskilde Festival is where they combine these passions for a weekend of drunken celebration. The four-day event is held about 30 minutes from the city completely, which means you can either go in for the full festival experience, or you can travel from the city to the festival each day. There are also day tickets if you don't have the power for the whole collection of facts. Kulturnatten (October) For something a little more high brow there's the Night of Culture. For one night only some 300 venues in the city stage theater performances, art exhibitions, concerts and poetry readings. Father Christmas Congress (July) One of the more bizarre fixtures in Copenhagen's calendar, the event is held in July--the slow season for Santas--at the Bakken amusement park, some 20 minutes north of the city. The most interesting of the event is a procession of Santas from all over the world along Stroget. Parents should be prepared for some embarrassed questions from the kids. Tivoli Gardens (November/December) These pleasure gardens make for a great day out any time of the year but to see them at their most attractive, visit from mid-November through December, when they are transformed into a fairy tale of lanterns and Christmas markets. There's also outdoor skating, a Christmas entertainment and the very Danish 'Nissekobing' village, home to more than 100 mechanical fairies. Question: If you are free in October, you can go to _ . Options: A: Roskilde Festival B: Kulturnatten C: Father Christmas Congress D: Tivoli Gardens
A: B

Q: I'm taking a test and have to guess the right answer to the question after the article. Article: Sensing phantom phone vibrations is a strangely common experience. Around 80% of us have imagined a phone vibrating in our pockets when it's actually completely still. Almost 30% of us have also heard non-existent ringing. Are these signs of madness caused by digital culture? Not at all. In fact, phantom vibrations and ringing indicate a fundamental principle in psychology. Psychologists use a concept called Signal Detection Theory to guide their thinking about the problem of perceptual judgments. Working through the example of phone vibrations, we can see how this theory explains why they are a common and unavoidable part of healthy mental function. When your phone is in your pocket, the world is in one of two possible states: the phone is either ringing or not. You also have two possible states of mind: the judgment that the phone is ringing, or the judgment that it isn't. Obviously you'd like to match these states in the correct way. True vibrations should go with "it's ringing", and no vibrations should go with "it's not ringing". Signal detection theory calls these faithful matches a "hit" and a "correct rejection" But there are two other possible combinations: you could mismatch true vibrations with "it's not ringing" (a "miss"); or mismatch the absence of vibrations with "it's ringing" (a "false alarm"). This second kind of mismatch is what's going on when you imagine a phantom phone vibration. What does that mean in terms of your phone? We can assume that people like to notice when their phone is ringing, and that most people hate missing a call. This means their perceptual systems have adjusted their bias to a level that makes misses unlikely. The unavoidable cost is a raised likelihood of false alarms of phantom phone vibrations. The trade-off between false alarms and misses also explains why we all have to put up with fire alarms going off when there isn't a fire. It isn't that the alarms are badly designed, but rather that they are very sensible to smoke and heat and biased to avoid missing a... Question: The writer tries to explain phantom phone vibrations_. Options: A: by analyzing some facts B: by giving some examples C: from the angle of biology D: from the angle of psychology

Q: I'm taking a test and have to guess the right answer to the question after the article. Article: My neighbor Mrs. Gargan first told me about it. "Have you seen the tree?" She asked as I was sitting in the backyard enjoying the autumn twilight . "The one down at the corner," she explained. "It's a beautiful tree--all kinds of colors. All the passers-by stop to have a look. You ought to see it." I told her I would, but I soon forgot about the tree. Three days later, I was jogging down the street when a splash of bright orange caught my eyes. For an instant, I thought someone's house had caught fire. Then I remembered the tree. I approached the tree to look at it closely. There was nothing remarkable about the shape of the tree. It was a medium-sized maple. But Mrs. Gargan had been right about its colors. Like the mess of an artist's palette , the tree blazed a bright crimson on its lower branches and burned with vivid yellows and oranges in its center, and deep red at its top. Through these colors were light green leaves as yet untouched by autumn. Walking closer I noticed several bare branches near the top, their small black branches scratching the air like claws. The fallen leaves lay like a red carpet around the trunk. As I was amazed at this beauty, I thought of Ralph Waldo Emerson's comments about the stars. "If the constellations appeared only once in a thousand years, imagine what an exciting event it would be. But because they're up there every night, we barely give them a look," he made a remark in Nature. I felt the same way about the tree. Because its beauty will last only a week, it should be especially precious to us. And I had almost missed it. Once in the 19th century when a man noticed a brilliant display of northern lights in the sky over Massachusetts, he rang a church bell to alert the whole town's people. That's what I felt like doing about the tree. I wanted to awake the countryside to its wonder. I didn't have a church bell, but as I walked home, I did ask each neighbor I passed the same simple but important question Mrs. Gargan had asked me: "Have you seen the tree?". Question: How did the author call on people to enjoy the wonder? Options: A: He rang the church bell. B: He passed on the same question. C: He awakened all neighbors up. D: He required people to the corner.
