[EX Q]: 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.

[EX Q]: Article: (PARIS) ----An English tourist who was highly praised for rescuing a three-year-old boy in Paris said he didn't think twice before diving into the freezing river. Tuesday's news said 25-year-old John Smith from England was the man who left the spot quickly after the rescue last Saturday. He lifted the little boy out of the water after he fell off the bank. He handed the child to his father, David Anderson, who had dived in after him. "I didn't think at all," John told the News. "It happened very fast. I reacted very fast." John, an engineer on vacation, was walking with his girlfriend along the pier when he saw something falling into the water. He thought it was a doll, but realized it was a child when he approached the river. Immediately, he took off his coat and jumped into the water. When he reached the child, he appeared lifeless, he said. Fortunately, when he was out of the water, he opened his eyes. Anderson said his son slipped off the bank when he was adjusting his camera. An ambulance came later for him, said John, who was handed dry clothes from onlookers. John caught a taxi with his girlfriend shortly after. The rescue happened on the day before he left for England. John said he didn't realize his story had greatly moved Paris until he was leaving the city the next morning. "I don't really think I'm a hero," said John. "Anyone would do the same thing."
Question: What is the probable reason why John was in Paris?
Options: (A) To meet his girlfriend. (B) To visit his parents. (C) To work as an engineer. (D) To spend his vacation.
