Example Input: Article: People like to look in the mirror often when they have a young and beautiful face. However, when one grows old, nobody wants to see their wrinkled old face in the mirror any more. So, many old people seldom look at their faces in the mirror. This is completely wrong. According to Wu Zhenyun, a professor from the Psychological Research Institute under the Chinese Academy of Sciences, a person's willingness to look in the mirror can reflect his or her mentality. When people don't care too much about their age, they will try to carry themselves with ease and natural poise . They don't mind looking in the mirror to see their own faces. Some people even love to look in the mirror from time to time to see whether they keep a good appearance. In this way, mirror becomes their best friend that help them to look confident. On the other hand, some people are afraid of being old. They don't want to see the wrinkles on their face and their hair turning grey. So they don't want to look in the mirror. This actually reflects a negative attitude they hold towards life. In the long term, they might suffer from psychological pressure or some sort of depression, which is actually not a wise act. " Everyone can make themselves look charming at every age stage. If one is confident, one will always look beautiful, it shows that they accept themselves." professor Wu said. Mirror cannot only give confidence to one. By looking in the mirror, one can even find the traces of some diseases from one's own face.

Example Input: Article: "How did Norman know, Sister Emma?" "He overheard you and Aryan arguing. I suspect that he purposely overheard on you. Norman knew or concluded what profession Aryan practiced. He might well have followed Aryan on his explorations. Whether he did or not is beside the point. When Aryan came back yesterday afternoon, Norman certainly decided that he had made some find, for Aryan told Norman that he would be leaving for the capital to meet the detective the next morning. He probably followed Aryan to your room and overheard what passed between you. "Since you could not act against the law of man and God, he would serve a natural justice in his own way. He took the jar of poison hemlock from the chemistry shop and when Aryan asked for a drink, he supplied it. Norman did not know the precise quantity needed and so Aryan did not suffer the full effects until after the bell called the community into the dining hall for the evening meal." Abbess was following Sister Emma closely. "And then?" "Then I began my investigation, and then the detective arrived seeking Aryan for an explanation for his death." "But who killed Norman?" "Norman knew that sooner or later he would be discovered. But more importantly in his guileless mind there was also the guilt of having taken a man's life to be considered. Norman was a simple man. He decided that he should accept the punishment--the honor-price of a life. What greater honor-price for the life of Aryan could he offer than his own? He also took a draught of poison hemlock." There was a pause.
Question: What may have happened to Aryan?
Options: (A) He was killed by poison. (B) He was found missing. (C) He was poisoned but saved. (D) He went away with what he had found.

Example Input: Article: After commuting, cooking dinner and doing household chores, the average parent has just 30 minutes to devote to their children in the evenings, according to a new study. One in four working parents worry that half an hour simply isn't enough, while almost half fret that they aren't a good enough parent during the week. However, parenting experts believe just 12 minutes a day may be enough for mothers and fathers to fully _ with their child -- as long as they ask the right questions. Child psychologist Dr Claire Halsey said asking a series of open-ended questions can help improve parents' relationship with their children. Among the questions recommended in the research are: "How many times have you smiled today -- what made you laugh?"; "Can you act out what you did at breaktime?"; "Who is taller -- mummy or your teacher?" and "What are the names of the toys you played with today?" Parents of older children are advised to start up a conversation with: "I've got a great story for you but I want one in return... you first!" or "Tell me some school gossip ... _ !" Dr Halsey, working with the makers of Ribena Plus, who commissioned the research, said: "There is no one as tough on their own parenting skills as a parent -- but this study shows there is no need for parents to be so harsh. It's hard for working parents to juggle all their responsibilities and it can feel like guilt is simply a parent's lot -- but it's absolutely not. By using clever tactics such as a little preparation alongside use of open-ended questions -- such as 'Tell me what the best bit about your day was?' -- parents can reduce the time worrying about chores and work and spend more time learning about their children's day."
