How is petroleum formed? Scientists believe petroleum comes from the remains of plants and animals (Remains are what is left after a plant or animal has died.) What exactly is petroleum? Petroleum is a mineral that is a mixture of hydrocarbons. It is an oily liquid, which may be brown, green, or black in colors. The word "petroleum" comes from Greek. It means "rock oil". Crude (, ) oil is petroleum that comes directly from deep in the ground. It is then taken to a refinery. a refinery is a kind of factory to refine oil. At a refinery the crude oil is separated into many parts. From the refined petroleum we get important things, such as gasoline, kerosene, fertilizer, detergents and a lot of other useful things. In fact, there are thousands of such things that we can get. Petroleum really is of great value!

Example Input: Article: It's hard to avoid looking like a fool on April Fool's Day. On April 1 each year, people play tricks on each other. These tricks are usually silly rather than mean. Classmates sometimes tie each other's shoelaces to their chairs.Teachers might hand out an impossibly difficult surprise test that scares students before they realize it's only a joke. Newspapers announce fake  contests (such as "Win an elephant!") and report on fake stories (like "UFO" lands in New York City). Forget gifts, songs and special foods--those are for the other holidays of the year. On April Fool's Day, the only tradition is to laugh (and maybe to cause a little bit of trouble). One April Fool's Day, when I was in high school, a group of students in my class played a very clever and funny trick on the teachers. They bought some chickens and set them free in our school cafeteria. The chickens ran all round the school, in and out of classrooms and under our feet. Feathers were flying everywhere. Teachers began running after the chickens, trying to catch them. Finally, they caught four of them. But the chickens were wearing numbered tags   around their necks, and the teachers discovered that they had only caught chickens No.1, 2, 3, and 5.Where was chicken No.4? The teachers looked and looked. They couldn't find another chicken. After a few hours, they realized that the students had played another joke on them: There were only four chickens in the first place! They've been tricked by the numbers on the chickens. It's been a long time since I was in high school, but that April Fool's Day remains one of my favorite memories from those years. 
 Answer: They wanted to play a trick on teachers.
Example Output: Why did students set chickens free?

Example Input: Article: "Soon,you're going to have to move out!"cried my neighbor upon seeing the largest tomato plant known to mankind,or at least known in my neighborhood.     One tiny 9-inch plant,bought for $ 1.25 in the spring.has already taken over much of my rose bed,covering much of other plants,and is well on its way to the front door.     Roses require a good deal of care,and if it weren't for the pleasure they give. it wouldn't be worth the work.As it is.I have a garden full of sweet-smelling roses for most of the year.Bushes must be pruned in early spring,leaving ugly woody branches until the new growth appears a few weeks later.It was the space available in the garden that led me into planting just one little tomato plant.A big mistake.     Soil conditions made just perfect for roses turn out be even more perfect for tomatoes.The daily watering coupled with full sun and regular fertilizing have turned the little plant into a tall bush.The cage I placed around it as the plant grew has long since disappeared under the thick leaves.     Now the task I face in harvesting the fruit is twofold.First.I have to find the red ones among the leaves,which means I almost have to stand on my head.and once found I have to reach down and under,pick the tomatoes and withdraw my full fist without dropping the prize so dearly won.I found two full-blown white roses completely hidden as I picked tomatoes in June. But they were weak and the leaves already yellow for lack of light.   Here I am faced with a painful small decision:To tear up a wonderful and productive tomato plant that offers up between ten and twenty ripe sweet tomatoes each day or say goodbye to several expensive and treasured roses.Like Scarlett in Gone With the Wind.I'll think about that tomorrow. 
 Answer: A lot of care and the right soil.
Example Output:
What are the requirements for the healthy growth of rose?
