Example Input: Article: Shane Thomas is a 10-year-old pianist from England. He's being called the next Mozart because of his amazing abilities. He has only been having piano lessons for four months, and practices four hours a week, but he has already played difficult classical pieces. He was just seven when he sat down at the piano, and could play at once. He also says he never gets nervous. When Shane was three years old, he said that he could play the piano, but nobody took him seriously. At school, he could listen to the teacher and do his work while composing in his head. Shame remembers all the melodies ,and when he gets home he plays them on the piano, while his father records them. Shane loves playing the piano, and when he grows up he wants to be a composer. His tutor, Richard Goffin-Lecar, says he is like Amadeus Mozart, who lived during the 18thcentury in Salzburg, Austria, and was one of the most famous composers ever. Mr. Goffin-lecar says, "I don't teach Shane very much. I just give him directions, then sit back and watch." His father, a single parent with two other children, says that although he has little money, he wants to send Shane to a good music school. "I'm a single father, but I have this gifted child. I don't have much money, but I want to give him the best teachers, and also take him into a studio to record."
Question: When did Shane tell others that he could play the piano?
Options: (A) At age three. (B) At age ten. (C) At age seven. (D) At age four.
Example Output: A

Example Input: Article: Every culture has a recognized point when a child becomes an adult, when rules must be followed and tests passed. In China, although teenagers can get their ID cards at 16, many only see themselves as an adult when they are 18. In the US, where everyone drives, the main step to the freedom of adult life is learning to drive. At 16, American teens take their driving test. When they have their license, they drive into the grown-up world. "Nobody wants to ride the cheese bus to school," said Eleanor Fulham, 17. She brought the pressure back to memory, especially from kids from wealthier families. "It's like you're not cool if you don't have a car," she said. According to recent research, 41% of 16 to 19-year-olds in the US own cars, up from 23% in 1985. Although, most of these cars are bought by parents, some teens get part-time jobs to help pay. Not all families can afford cars for their children. In cities with subways and limited parking, some teenagers don't want them. But in rich suburban areas without subways, and where bicycles are more for fun than transportation, it is strange for a teenager not to have a car. But police say 16-year-olds have almost three times more accidents than 18 and 19-year-olds. This has made many parents pause before letting their kids drive. Julie Sussman, of Virginia, decided that her son Chad, 15, will wait until he is 17 to apply for his learner's permit. Chad said he has accepted his parents' decision, although it has caused some teasing from his friends. "They say that I am unlucky," he said, "But I'd rather be alive than driving, and I don't really trust my friends on the road, either." In China, as more families get cars, more 18-year-olds learn to drive. Will this become a big step to becoming an adult?
Question: Which may serve as the BEST title of the article?
Options: (A) Cars Helping You to Grow-Up (B) Driving into the Grown-Up World (C) Teenagers' Driving in America (D) Recognized Point of Becoming an Adult
Example Output: B
