In this task, you're given an article, a question which often contains a blank and four options (associated with "A", "B", "C", "D"). Your task is to find the correct answer (from the given options) for the question from the given article and return one of the options from "A", "B", "C", and "D". Do not generate anything else apart from one of the following characters: "A", "B", "C", "D". There is only one correct answer for each question.

Example Input: Article: There are robots all around us. Some do very complicated jobs like flying airplanes and driving subway trains. and some do one simple job. When an automatic washing machine is switched on, water pours in. The machine waits until the water is warm enough for washing clothes. It does this by "feedback" . Information about what is happening is feedback into the robot to tell what to do next. Our eyes, ears and other senses are our feedback. They tell us what is going on around us. So robots are like human beings in two ways. They work and they have feedback. In some ways robots are better than human beings. They work quickly and do not make mistakes. They do not get bored doing the same job over and over again. And they never get tired. So robots are very useful in factories. They can be taught to do many different jobs. First their electronic brain must be shown how the job is done. A person moves the robot's "arms" and "hands" through each part of the job. The most intelligent robots can move and see. Their eyes are cameras. Their fingers can feel shapes and sizes of the objects. These robots have computer brains linked to their eyes and fingers, which control their actions. The expensive robots are used in scientific research. They do such job as handling radioactive materials.
Question: In this passage the author tells us that _ .
Options: (A) robots are very popular (B) there are various kinds of robots (C) we see robots only at certain times (D) robots can be easily controlled
Example Output: A

Example Input: Article: As a school teacher, Inderjit Khurana used to take the train to work. And one day, at the station, she saw dozens of children who spent their days begging from train passengers rather than going to school. She learned that it was not a rare problem and that millions of children in India lived on the streets. Realizing that these children would never be able to escape poor life and homelessness without education, and that it would be impossible to send these children to school, Inderjit decided to create a model program---taking the school to the most out- of-school children. Khurana's train platform schools aim to provide a creative school form and give children the basic levels of education. Her last goals reach far beyond the 20 platform schools she and her colleagues have created in India's Bhubaneswar region. She is determined that her program will become a model for changing the lives of the poorest children throughout India and the world. Khurana founded the Ruchika Social Service Organization(RSSO) in 1985. The teachers gather the children together between the stops of the train for reading, writing, maths and history taught through songs and other teaching tools. Khurana recently comes to realize that the education of these children is impossible when the most basic needs of their families are not being met. So she also provides food and medicine for their families. Khurana insists that every child have the right to an education and that if a child cannot come to the school, then the school must come to him or her.
Question: Khurana's final aim is to _ .
Options: (A) make the poorest children's lives better (B) put an end to the problem of children's dropout (C) attract more students to her platform schools (D) set up 20 platform schools throughout India
Example Output: A

Example Input: Article: As rules, laws are people's rights and responsibilities toward society. Laws are agreed on by society and made official by governments. Some persons look on laws with fear, hatred, or annoyance. Laws seem to limit people's freedom to do many things they would like to do. Though laws may prevent us from doing things we wish to do at the moment, laws make everyone's life safer and more pleasant. Without laws we could not hold on to our property; we could not go to bed at night expecting to wake up in the morning and find that we had not been robbed; no stores in which we buy food, clothes, and other necessities could stay open and sell to us. Our banks would not be safe places to keep our money. Social life would be impossible without laws to control the way people treat one another. It is not the laws that should be feared but the trouble that comes to everyone when laws are broken. Once this is understood, a citizen will not fear or hate the law. Understanding the need for good laws and the evil results of breaking laws is the first requirement of good citizenship and government. Philosophers once believed that in prehistoric time people lived without laws in a "state of nature". People were free to do as they pleased unless someone stronger stopped them by force. As a result, life became so dangerous and unsafe that leaders had to create laws to protect life and property. This is no longer believed to be true. Scholars now think that as soon as people began living in small groups, they worked out rules for getting along with one another. In time everyone accepted and supported the rules. Manners, customs and beliefs controlled the living habits and behavior of the group. Such rules and habits of life are called folkways. Folkways are probably the real meaning of human laws, as well as of religion, morals, and education. As life became more complex, folkways became more complete guides to living. After thousands of years, some of the important folkways were put into writing as the earlier laws. And as life grew more and more complicated with faster transportation and the rise of modern industry and big cities, more human acts and interests had to be ruled by law. This led to a great increase in the number of laws. But we know that unless laws are enforced, they cannot protect us. Poorly enforced laws invite crime and violence. So we agree that the best protection against crime is planned social change and law reform -- to reduce the causes of crime and to encourage people to obey the laws. Such a solution would join a sound system of law enforcement with forces working to prevent crime. To attain this goal, all citizens must understand the need for good laws and for their enforcement.
Question: Some persons look on laws with fear, hatred, or annoyance, because _ .

A
