Example Input: Article: How men first learned to invent words is unknown, in other words, the origin of language is a mystery. All we really know is that men, unlike animals, somehow invented certain sounds to express thoughts and feelings, actions and things, so that they could communicate with each other; and that later they agreed upon certain signs, called letters, which could be combined to represent those sounds and which could be written down. Those sounds, whether spoken, or written in letters, we call words. The power of words, then, lies in their association--the thing they bring up before our minds. Words become filled with meaning for us by experience; and the longer we live, the more certain words recall to us the glad and the sad events of our past; and the more we read and learn, the more the number of words that mean something to us increase. Great writers are those who not only have great thoughts but also express these thoughts in words which appeal powerfully to our minds and emotions. This charming and telling use of words is what we call literary style. Above all, the real poet is a master of words. He can _ his meaning in words which sing like music and which by their position and association can move men to tears. We should, therefore, learn to choose our words carefully and use them accurately, or they make our speech silly and impolite.
Question: Where does the real power of the words come from?
Options: (A) From the words themselves. (B) From their characteristics. (C) From their curiosity. (D) From their association.
Example Output: D

Example Input: Article: To most of us,school means classes,teachers,schedules,grades,and tests.But for the children at Sudbury Valley School in Massachusetts,school is very different. Firstly,there are no lessons.All the children,aged between 4 and 19,do whatever they want.There are no teachers--only "staff members".The idea behind this is that you do not need to make children learn,because children want to learn anyway."You do not need to say to a three yearold,'Go explore your environment.'You can't stop them!" says Daniel Greenberg,a founder of the school."But if you make children do what you want all day,they will lose all taste for learning." At Sudbury Valley School,you will permit children to talk,read,paint,cook,work on computers,study French,play the piano,climb trees or just run around.Two boys spent three years just fishing! The other way that Sudbury Valley School is different is that the children can decide the rules.Every week,there is a school meeting where both children and staff have one vote each--even the fouryearolds.They decide the school rules,how to spend the school budget,and even which staff they want and do not want any more. When the school first opened in 1968,people said it would never work.But today,the school has 200 students,and 80%of its students go on to college. Even the two boys who went fishing all the time have successful careers today.One of them is a musician and the other is a computer scientist.
Question: What is the main topic of the article?
Options: (A) An unusual school. (B) Children's hobbies. (C) A school without rules. (D) Education in the US.
Example Output: A

Example Input: Article: My mother is taking a tour of the new house via Skype. I leaned the laptop so she can see where she's going,pleased that our Internet connection in Zimbabwe is holding. "This is the living room," I say. Then I tell mydaughter,s;Show Grandma the bed for the mummy and the daddy. " From a continent away, Grandma gave herapproval. Mum had a dollhouse,too. My grandmother,a single mother, did not have enough money to buy my mother areal dollhouse. So Mum made do,laboring over her square cookie tin for years. She stuck patterns on the bright walls : tin cans of jam and bags of flour to make sure the dolls' store was overflowing. My mother passed her love of life in miniature( ) on to me very early. At age 5,1 made chests of drawers for my dollhouse bedroom from matchboxes glued together. Unlike my mother,l was given some ready-made doll furniture and accessories. My mother encouraged me,always responding to my calI,"Come to see what I've made Lrur IIly clollhuuse ! " I spent hours writing a book with the unoriginal but certainly accurate title " How To Make Dolls' House Furniture". The book was lost in a household move. But the satisfying feeling of filling up blank pages with my own ideas stayed with me,pushing me into a career centered on words. My daughter turned 3 recently, and last month I put a strong empty cardboard box,about the size of a tea tray ,in Cassia's bedroom. I searched the shops for dollhouse furniture. But an afternoon's searching yielded only a pink plastic toilet and sink. It doesn't matter,l told myself. I showed Cassia how to make plates for her table from coloured buttons. Fascinated, she collected black stones. What my mother gave me was much more than a fascination with tiny things :It was the ability to view things from a new perspective , to put oneself in another person's shoes , and to solve problems with whatever is at hand.
