TASK DEFINITION: In this task, you're given an article, a question which often contains a blank, four options (associated with "A", "B", "C", "D") and the answer to that question. Your task is to classify whether the given answer is correct or not by providing "Yes" or "No", based on the article.
PROBLEM: 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.

Asnwer: D

SOLUTION: Yes

PROBLEM: Article: Poet William Stafford once said that we are defined more by the detours in life than by the narrow road toward goals. I like this image. But it was quite by accident that I discovered the deep meaning of his words. For years we made the long drive from our home in Seattle to my parents' home in Boise in nine hours. We traveled the way most people do: the fastest, shortest, easiest road, especially when I was alone with four noisy, restless kids who hate confinement and have strong opinions about everything. Road trips felt risky, so I would drive fast, stopping only when I had to. We would stick to the freeways and arrive tired. But then Banner, our lamb was born. He was rejected by his mama days before our planned trip to Boise. I had two choices: leave Banner with my husband, or take him with me. My husband made the decision for me. That is how I found myself on the road with four kids, a baby lamb and nothing but my everlasting optimism to see me through. We took the country roads out of necessity. We had to stop every hour, let Banner shake out his legs and feed him. The kids chased him and one another. They'd get back in the car breathless and energized, smelling fresh from the cold air. We explored side roads, catching grasshoppers in waist-high grass. Even if we simply looked out of the car windows at baby pigs following their mother, or fish leaping out of the water, it was better than the best ride down the freeway. Here was life. And new horizons. We eventually arrived at my parents' doorstep astonishingly fresh and full of stories. I grew brave with the trip back home and creative with my disciplining technique. On an empty section of road, everyone started quarreling. I stopped the car, ordered all kids out and told them to meet me up ahead. I parked my car half a mile away and read my book in sweet silence. Some road trips are by necessity fast and straight. But that trip with Banner opened our eyes to a world available to anyone adventurous enough to wander around and made me realize that a detour may uncover the best part of a journey----and the best part of yourself.
Question: Why did the author use to take freeways to her parents' home?
Options: (A) She needn't stop on the way. (B) It would be faster and easier. (C) Her kids would feel less confined. (D) She felt better with other drivers nearby.
Asnwer: D

SOLUTION: No

PROBLEM: Article: Does it drive you crazy that your cell phone needs to be frequently charged for hours? A team of scientists led by professor Harold Kung at Northwestern University in the US may have solved your problem. They developed a lithium ion batery that holds 10 times as much power and charges 10 times more quickly than standard batteries, according to the BBC in a report on November 15. Lithium ion bateries are rechargeable and are widely used in cameras, smartphones and laptops. They charge through a chemical reaction in which lithium ions are sent between the two ends of a battery. How much power the battery holds and how fast it charges are limited by two things:how many lithium ions it has and how quickly these ions move. Current rechargeable batteries have an anode made of many carbon-based graphene sheets. To increase energy capacity, former experiments have tried to replace the carbon with silicon, which can hold far more lithium ions. However, this method did not work because the silicon was not stable enough. Kung's team managed to stabilize the silicon. They put clusters of silicon between the graphene sheets like a sandwich so that the silicon could not move around freely and take away the energy. The speed at which a battery charges is hindered by the shape of the graphene sheets because it takes a long time for the lithium to travel from one side of the sheet to the other.Sometimes a "traffic jam" occurs around the edges of the graphene. To solve this problem, Kung's team used a special chemical process to create tiny holes of 10 to 20 nanometers wide in the graphene sheets so the lithium ions would have a "shortcut" and be able to travel directly to the other side. This reduced the time it took the battery to recharge. About 15 minutes of charging can last more than a week. "Even after 150 charges, which would be one year or more of operation, the battery is still five times more effective than lithium ion batteries on the market today," said Kung. The technology could be widely available within five years, the researchers said.
Question: What is the major problem of current rechargeable batteries?
Options: (A) They are not very stable. (B) They cannot hold enough silicon. (C) They have limited energy capacity. (D) The space between the graphene sheets is too big.
Asnwer: C

SOLUTION:
Yes
