Input: Consider Input: Article: Imagine you are standing on the 70thfloor of the Empire State Building, staring at the cityscape. Suddenly a man pushes past you, opens the window and announces his intention to jump. You yell out, "Stop! Don't do it!" the six-foot-five figure turns to you and menacingly   says, "Try to stop me and I'll take you with me!" "Umm... No problem, sir. have a good trip. any last words?" "Let me tell you my troubles," he says, "my wife left me, my kids won't talk to me, I lost my job and my pet turtle died, so why should I go on living?" Suddenly you have a flash of inspiration. "Sir, close your eyes for a minute and imagine that you are blind. No colors, no sights of children playing, no fields of flowers, no sunset. Now imagine that suddenly there's a miracle. You open your eyes and your vision is restored! Are you going to jump? Or will you stick around for a week to enjoy the sights?" "I'll stay for a week." "But what happened to all the troubles?" "I guess they're not so bad. I can see!" " _ " If you really appreciate your eyesight, the other pains are insignificant. But if you take it all for granted, then nothing in life will ever truly give you joy. Actually, there are misconceptions on the road to happiness. misconception1: "Once I know the tools for being happy, then it will work like magic." Don't expect the results to come automatically. It is possible to understand how to achieve happiness, yet not put it into practice. In fact, many people actually prefer to be comfortable and unhappy, rather than bear the discomfort of changing their habits. Just as learning any new skill requires effort, you have to be willing to invest serious effort to achieve real happiness. Misconception 2: "if I become content and satisfied with what I have, I'll lose my motivation to achieve more." Now ask someone who is depressed, "Let's go fishing!" "I'm tired. Maybe tomorrow. And anyway, I might rain..." in reality, happy people are energetic and ambitious. There's never enough time to do everything they want to do. Misconception 3: A beautiful Sunday afternoon, you're in the park having a picnic with friends. Suddenly one person complains: "who forgot the forks? It's too hot for volleyball. I want to go home already." When our mood negatively affects others, we recognize we have duty to be happy and not spoil the fun. But what about when we're at home with our family? Or when we go into the office on Monday morning? like an open pit in the middle of the road, a sourpuss  is a public danger. Being happy is part of being considerate to the people around us.

Input: Consider Input: Article: I must have been about fourteen then, and I put away the incident from my mind with the easy carelessness of  youth. But the words, Carl Walter spoke that day, came back to me years later, and ever since have been of great value to me. Carl Walter was my piano teacher. During one of my lessons he asked how much practicing I was doing. I said three or four hours a day. "Do you practice , an hour at a time?" "I try to." "Well, don't," he exclaimed. "When you grow up, time won't come in long stretches.    Practice in minutes, whenever you can find them five or ten before school, after lunch, between household tasks. Spread the practice through the day, and piano-playing will become a part of your life." When I was teaching at Columbia, I wanted to write, but class periods, theme-reading, and committee meetings filled my days and evenings. For two years I got practically nothing down on paper, and my excuse was that I had no time. Then I remembered what Carl Walter had said. During the next week I conducted an experiment. Whenever I had five minutes unoccupied, I sat down and wrote a hundred words or so. To my astonishment, at the end of the week I had a rather large manuscript ready for revision, later on I wrote novels by the same piecemeal method. Though my teaching schedule had become heavier than ever, in every day there were idle moments which could be caught and put to use. I even took up piano--playing again, finding that the small intervals of the day provided sufficient time for both writing and piano practice. There is an important trick in this time--using formula: you must get into your work quickly. If you have but five minutes for writing, you can't afford to waste four chewing your pencil. You must make your mental preparations beforehand, and concentrate on your task almost instantly when the time comes. Fortunately, rapid concentration is easier than most of us realize. I admit I have never learnt how to let go easily at the end of the five or ten minutes. But life can be counted on to supply interruptions. Carl Walter has had a tremendous influence on my life. To him I owe the discovery that even very short periods of time add up to all useful hours I need, if I plunge in without delay. 
 Question: Which of the following statements is true? 
 Options: (A) The writer didn't completely take the teacher's words to heart at first. (B) Carl Walter has had a great influence on the writer's life since he became a student. (C) The writer owes great thanks to his teacher for teaching him to work in long stretches. (D) Rapid concentration is actually more difficult than most people imagine. 
 Asnwer: A

Output: Yes


Input: Consider Input: Article: Researchers at San Diego Zoo have been studying what has been described as the "secret language" of elephants. They have been monitoring  communications between animals that cannot be heard by human ears. The elephant's call will be familiar to most people, but the animals also give out growls  . Their growls, however, are only partly audible  ; two-thirds of the call is at frequencies that are too low to be picked up by our hearing. To learn more about the inaudible part of the growl, the team attached (......) a microphone sensitive to these low frequencies and a GPS tracking system to eight of the zoo's female elephants. The researchers could then relate the noises the animals were making to what they were doing. Matt Anderson, who led the project, told BBC News, "We're excited to learn how they interact and contact with one another." The team has already learned that pregnant females use this low frequency communication to announce to the rest of their long gestation   of over two years, in the last 12 days we see the low part of the growl, which we can't hear. This we believe is to announce to the rest of the herd that the baby is upcoming," said Dr Anderson. The researchers believe that this also warns the elephants to look out for coming danger. "You may think that a baby calf of about 300 pounds would not be as open to predation   as other species," he says. "But packs of hyenas   are a big threat in the wild." Female elephants are only in season for around four days every four years and these calls can be heard by males more than two miles away. 
 Question: Why some elephants' call is called "secret language"? 
 Options: (A) Because it can't be heard by human ears. (B) Because it can only be heard by female elephants. (C) Because people don't know its meanings. (D) Because people haven't studied it completely. 
 Asnwer: A


Output: Yes
