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.

Article: It is a reply to a letter written by Zhai Mingjun, a 16-year-old girl in the class. The two astronauts thank the student for her concerns and wish the class luck in their future studies. "I' m so happy that the two space men replied with a few encouraging words," said Zhai. Her letter was one of the 10 winning letters taken into space by Fei and Nie, who have succeeded in traveling space in the Sixth Shenzhou Spaceship. Zhai wrote the letter as if she were a younger sister of the astronauts. "As the single child in my family, I always hoped that I would have an elder brother that I could be proud of," Zhai said. "I thought that the astronauts would be lonely during such a long space trip. I hoped they would feel happy and warm when reading my letter." Many of Zhai' s classmates also wrote their words of encouragement and admiration to the astronauts. "The letter to the astronauts made us believe that we can also be part of the manned space programme," said Zhao Dongxu. All the students have high expectations for China' s future space programme. "I heard that Snoopy is the mascot for US astronauts. I hope I can design a mascot for our heroes," said Liu Mengjie, 16. "A physics class taught by astronauts in outer space would be very interesting. I want to be the astronaut who teaches students about zero gravity with my head upside down in the spaceship," said Han Yinan. Many students think that the manned space program is still far away from them. But they feel proud that ordinary students could participate in such a great scientific achievement and hope there will be more possibilities to take part.
