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.

Input: Consider Input: Article: Coca-Cola is probably the most famous brand in the world, and in some areasyou can even access it easier than clean drinkable water. Although the company is trying to present itself as a health-conscious company, you can't really say that drinking cola is healthy for you. Still, we all drink cola, some more and some less, and we tell ourselves that it's all okay as long as we don't overdo it. However, Coca-Cola has other functions besides drinking. Cola removes the tarnish from old pennies. Got some old rusty pennies? Not to worry! Put them inside a glass of cola and let them rest for a while. When you get them out, you'll have shiny pennies that will look as if they were coined a couple of days ago. If you couldn't clean those pennies with industrial acids, just buy a can of cola and let it do its magic! You can remove gum from your hair with cola. If you've got gum stuck in your hair and don't know a better way to get it out, don't worry, you won't have to cut it. Just pour some cola into a bowl and dip the part of your hair with gum on it inside. Leave it for a couple of minutes and then simply wipe off the gum. You can make an exploding fountain. You probably know about this one. You can make an exploding fountain by putting a mint inside a two-liter bottle. Then move away from the bottle and get ready for a Coca-Cola explosion. This is a fun thing to do, but it is also a warning -- don't eat a mint and drink cola at the same time, because a similar thing could happen to your stomach.
Answer: Take the place of acids.

Output: What can cola be used to do?

Input: Consider Input: Article: Are _ born or made? In my case it was definitely made. In my early 20s, I hardly went to bed before midnight, and I would always get up late the next morning. But after a while I couldn't ignore the high relationship between success and rising early. On those rare occasions where I did get up early, I noticed that my productivity was always higher. So I set out to become a habitual early riser. But whenever my alarm went off, my first thought was always to stop that noise and go back to sleep. Eventually some sleep research showed that my strategy was wrong. The most common wrong strategy is this: supposing you're going to get up earlier, you'd better go to bed earlier. It sounds very reasonable, but will usually fail. There are two main schools of thought on sleep patterns. One is that you should go to bed and get up at the same time every day. The second school says you should go to bed when you're tired and get up when you naturally wake up. However, I have found both are wrong if you care about productivity. If you sleep at fixed hours, you'll sometimes go to bed when you aren't sleepy enough. You're wasting time lying in bed awake. My solution is to combine both methods. I go to bed when I'm sleepy and get up with an alarm clock at a fixed time. So I always get up at the same time (in my case 5 a.m.), but I go to bed at different times every night. However, going to bed only when I'm sleepy, and getting up at a fixed time every morning are my ways. If you want to become an early riser, you can try your own.
Answer: Because he / she found that the productivity was higher.

Output: Why did the author want to become a habitual early riser?

Input: Consider Input: Article: What kind of life do you seek for? One that is frustrating and full of complaints every day? Or one that is filled with thankfulness, gratefulness and a positive mind? The moment we open our eyes each day, we should be grateful that we are still alive. We are given a brand-new day. We are given another day to love. We are given another day of hope. We are given another chance to do whatever we have failed to accomplish. Those who have chosen to leave this place do not have any second chance. We should be grateful every day. By being grateful, we will treasure the things around us. We will learn to appreciate life in a better way. Treat others better and find ourselves in a better mood every day. When we are thankful and grateful for the things we have, the universe tends to give us more. By being thankful and grateful for our personal health, we will focus our attention on it and we would want to have a better well-being for our health. We will want to eat healthier food to nourish our body. After all, the body is the temple of our soul. We have to treat it well so that it can carry us a longer journey in life. When we face problems in life, be thankful and grateful too. They are designed specifically for us so that we will be stronger and wiser. We are like a strong oak tree, facing the _ weather time to time. After each storm, we will grow stronger and strengthen our foundations for the next harsh weather. The year 2013 has come to an end.
