Input: Consider Input: Article: As the new semester begins, millions of college students across the country are trying hard to remember how best to write a paper or, more likely, how best to delay that paper. Procrastination is the thief of time and a lot of students suffer from it. They can spend whole days in the library doing nothing but staring into space, eating snacks, surfing the Internet, watching videos and looking at other students sitting around them, who, most likely, are doing nothing either. Paralyzed by their habit to procrastinate, they write micro blogs about their fears, asking their online friends if they sometimes have the same issue. But this does nothing to break the spell . According to a recent report, 95 percent of us procrastinate at some point and 20 percent of the world's population are always procrastinating. The figures are disappointing. Procrastinators are less wealthy, less healthy and less happy than those who don't delay. Procrastinators like to find excuses to justify their behavior, but BBC columnist Rowan Pelling says they are all wrong. Many procrastinators tell themselves they are perfectionists who work best under pressure. Pelling says this is nonsense, as work done at the last minute is more likely to have mistakes than work done on time. The behavior of procrastinators often makes them feel ashamed, inconveniences others and annoys loved ones. Pelling also points out that procrastination feels particularly delinquent in a society that thinks of speedy action as admirable, and, at times, even as a moral good. Fortunately, social scientists have thrown their weight behind efforts to understand this behavioral mistake and offer strategies to control it. Piers Steel, a Canadian social scientist and author of The Procrastination Equation, believes human is "designed" to procrastinate. Nevertheless, he suggests a couple of good ways to get through the task at hand.
Question: Which behavior belongs to procrastination?
Options: (A) Never dream away the time. (B) Always complete the tasks ahead of time. (C) Never put off till tomorrow what should be done today. (D) Always wait to work until the "good mood" or "good time".

Output: D

Input: Consider Input: Article: When policy experts debate climate change solutions, they often talk about "a price on carbon." They are arguing about whether companies should pay when they put carbon pollution in the air. Proponents say that it's simple economics -- if it's free to pollute, you'll get a lot of pollution. Opponents claim it will raise the cost of energy that's produced from high carbon sources, like coal. But here's the secret that most people seem to be missing: There already is a price on carbon, and it's paid by the taxpayers. Carbon pollution, like every other form of pollution, has an impact on the environment. Throwing waste into a river will cause the fish to die and the people who drink the water to get sick. And when you produce carbon pollution, you get climate change -- sea level rise, stronger storms, severe droughts, damage to agriculture, and more. All of those impacts cost money. Insurance rates go up when storms get more destructive. Taxes increase when cities have to rebuild bridges and roads. Military budgets go up when droughts and population changes cause conflicts. Not to mention impacts on agriculture and health care costs. In other words, the price on carbon is what we all pay when there is no market force to limit the pollution that causes climate change. So the debate is really about who will pay that price -- the companies who are making a profit from the fossil fuels, or the taxpayers who pick up the cost now? Right now, we have private profit and public cost. It's just like if we allowed every business to throw its garbage in the street because it's too expensive to have it moved away properly. Does it add a little bit to your dinner check to require that restaurants dispose of their trash properly? Sure. But it would be more expensive for you if the city had to clean the streets of their garbage every day. So just like we put a "price on garbage" we need a "price on carbon pollution." Now, a "price on carbon pollution" can mean a lot of things. You could tax companies based on the amount of carbon pollution they produce, and return the money to taxpayers. You could put a limit on how much they can produce, thereby requiring them to invest in ways to conduct business in a less polluting way.
Question: What do the policy experts argue about carbon pollution?
Options: (A) Whether the companies should pay for it. (B) Whether taxpayers could get profit from it. (C) Who have the ability to change it. (D) How much should be paid for it.

Output: A

Input: Consider Input: Article: On my first day of work at Moro Assurance, I arrived nervously, totally wet and nearly half an hour late. I had forgotten to take an umbrella, had missed the bus and was mow ready for a good scolding . It was then that I met Nicky Jonathan, the Managing Director. She was a small, birdlike woman. Her appearance gave others the impression of a nervous, easily-flustered person. I soon learnt, however, that her true character was calm, warm and kind, yet very professional. After reminding me that lateness would not be tolerated in the office, she laughingly admitted to me that she had been over an hour late in her first morning because she had lost her way, which was typical of her. After a wet, awful morning, this kind office manager led me to my seat; yet her kindness and super ability didn't stop surprising me there. During the years I worked with her, my admiration for Nicky steadily increased. Her ability to deal with several matters at once seemed almost miraculous . I remembered one occasion when nearly everyone in the office had gone down with the flu, yet Nicky managed to keep the office running smoothly without seeming stressed. The most striking thing about Nicky was her understanding towards others. _ If she sensed that something was wrong, she would call you into her office and encourage you to talk. Not only was she a good listener, but the advice she offered was always sound as well. All in all, Nicky is the most admirable person I've ever mer. I will always remember her as the "guiding light" in my working life.
