TASK DEFINITION: In this task, you're given an article and an answer. Your task is to generate the question for the answer based on the given article.
PROBLEM: Article: During my many contacts with people in China, I have been asked by two different people what I would recommend to them so that they could be happy. One of these people was my student and friend who began her question by saying I always appeared happy to her. She then asked how I could be this way and if I could teach her how to be happy all the time. The other inquiry was basically the same and came from the secretary of a company for which I was doing some work. The first one to ask was my student and in thinking about an answer I even explored in class the idea of optimism and pessimism, of people who feel the glass is always half full and those who think it is half empty. It was easy to show that different people react differently to the same situations and conditions but that didn't bring me much closer to understanding why. About two months later I was riding to the airport in a taxi with the company secretary who asked me the same question and it made me think. Why did both these ladies feel they needed help to become happy? Indeed, why did either of them think they were not happy? Why did they choose to ask this question of me? Why are some people generally happy while others are not? Certainly if someone is healthy, it might be expected that they are happy, and this is probably true. However, some people have money and health but have a miserable _ that makes it difficult for them to have friends and meaningful relationships. Similarly, one would expect those who have little to complain about their fate and many do, but others are able to enjoy what they have and enjoy life. It seems the difference must lie within the people. What we may be looking at is acceptance of a personal set of circumstances and the contentment which flows from that. _ should not mean, however, that those people cannot wish for something better. If the difference between people who are happy and those who are not lies within the people themselves, can happiness be learned? I think there are things we can do, such as dreaming of the future, which can give us the sort of positive outlook which will generally make us happy people.
Answer: Those who feel the glass is always half full are pessimistic.

SOLUTION: According to the passage, which of the following is true?

PROBLEM: Article: THE first night in Yosemite had been awful. I hadn't been able to sleep and I was stuck in a too small tent with my wife and two kids. "Things haven't worked out," I said to myself. But, like so many other things I complain before my morning coffee, this one was ridiculously off-key. Things weren't bad; they were good. A hundred yards(91 meters) away was Summit Lake, with its wonderful early morning mists shimmering off the water. A couple of miles to the southwest was the base of the Lassen Peak Trail. The base was 8,000 feet (2,400 meters) above sea level, huge snow banks dotting the place even in mid August. It was beautiful. We fired up the camp stove, got out our cold boxes from the heavy metal locker ,fired up some bacon, cut open some bread, and boiled up a cup of coffee. Half an hour later, my 6-year-old daughter and I were in the parking lot of the Lassen Peak Trail, getting ready to hike. We wouldn't make it all the way-- young legs get pretty tired on a steep mountain path, but it didn't matter. We would see great views spread out below us, the volcanic ash that layered on the earth turning the melting snow a mysterious pink as the sun struck it. Later, on the hike, I felt stupid about my morning complaints. Everything had been worthwhile. It gave me enormous satisfaction to see my daughter so excited about the view from the mountain. Yes, camping is uncomfortable. But there's also something wonderful about being so close to nature. Just as importantly, there's something about getting young children out of their increasingly technology-filled comfort zones and forcing them to encounter the non-cyber world around them. We lose something when we spend all our time cocooned inside a carefully constructed modernity, when read about daily affronts to the environment, yet don't fully realize what is at risk, removed as we are from nature. It's a good thing to reconnect every so often with the Great Outdoors. By Sasha Abramsky
Answer: Uncomfortable.

SOLUTION: How did the author first feel about camping in Yosemite?

PROBLEM: Article: The cost of college textbooks has risen sharply from 2002 to 2014. As a result, students have to look for other less expensive options , such as renting books. Now, they find another way, that is, using textbooks on the Internet, uploaded by other students. It is hard to know how popular this practice will be, but many college students around the country are uploading their expensive college textbooks onto the Internet, so that other students can download them for free and avoid the big fees. A year ago, a student wrote a blog called Children of the Stars about a professor who insisted that students buy the newest edition of a specific sociology book for more than $200 and didn't allow them to purchase an older paperback edition of the same book for $5. The student wrote, "The newest edition of the book is so expensive. Fortunately, we found the electronic one online, which is very cheap. This is why we downloaded. " The blog is followed by a list of websites where people can download books. Curious about how varied the selection of books was and how easy it was to download them, Vocativ.com decided to do an experiment. The workers of it picked five typical and important courses of freshmen and tried downloading all these textbooks on the websites offered by the student who wrote Children of the Stars. They typed the titles of these textbooks into a computer, and found them immediately. Within minutes, they had four textbooks on their hard drive. It is illegal to upload or download copyrighted materials without permission, but students still do it due to its advantages. Besides, schools haven't taken action to stop it.
Answer: Because it is lower in cost.

SOLUTION:
According to the passage, why do many students choose to download textbooks?
