Mr. John Evans had never found the time or money to make the trip from his home in Forest Fach, near Swansea. But, when British Rail offered him an all-expenses-paid birthday trip to the capital he just could not refuse. He arrived at Paddington Station and smartly turned out in his best suit, favorite Panama hat and a red rose in his buttonhole. "It's very exciting. There's no doubt about it," he said. Until yesterday he had never been far from home, except for one trip to Aberdeen. "But I've been on the seas to that faraway land called Ilfracombe 21 miles from home," he joked. Mr Evans, who spent 60 years working as a miner in South Wales, almost made the journey to London once before, at the turn of the century. "There was a trip to the White City but it was ten shillings return from Swansea -- too much I thought. All my money went to the family then," he said. During the next two days Mr. Evans will be taken on a short tour of London to see the sights. Top of his list is a visit to the House of Parliament organized by his MP, Mr. Gareth Wardell. The only arrangement he does not care for is the wheelchair provided for him if he gets tired. "I don't like the chair -- people will think I am getting old. " he said. His secret for a long and healthy life has been well publicized -- no wine, no tobacco and no anger. Before setting off from Swansea with his 76-year-old son, Amwell, he said jokingly, "I'm glad to see they've given me a return ticket. " Question: The probable explanation to Mr. Evans' long life lies in   _  . Options: A: his good living habits B: his hard working for the family C: his sticking to his hometown D: his living conditions near the Swansea

What most passengers don't realize is that their minute is already there.     Every commuter train that departs from New York Cityabout 900 a d leaves a minute later than scheduled. If the timetable says 8:14, the train will actually leave at 8:15.In other words, if you think you have only a minute to get that trainwell, relax. You have two.     The courtesy minute , in place for decades and published only in private timetables for employees, is meant for those who need the extra time to get off the platform and onto the train.     "If everyone knows they get an extra minute, they're going to waste time doing unimportant things," explained Marjorie Anders, a spokeswoman for the Metro-North Railroad. Told of this article, Ms. Anders laughed. "Don't blow our cover!"she said.     Entirely hidden from the riding public, the secret minute is an odd departure from the railroad culture of down-to-the-second accuracy. The railroad industry helped invent the concept* of standard time, and time zones were established in the United States in the 1880s, 35 years before they were written into law. And most commuters know their train by the accurate minute it departs. The trains quickly make up the minute:at all other stops, the public timetable is carried out. The courtesy minute does not exist at commuter railroads in Chicago, Los Angeles, Philadelphia, or San Francisco. But in New York, the secret minute dates back decades.     "That's been done forever, from my knowledge," said Jack Swanberg, 70, an unofficial historian of Metro-North. "I was the trainmaster starting in 1970 and I'm sure it's been the case since 1870 for all I know." Question: The passage mainly talks about  _  * Options: A: the railroads in the US B: .the secret of New York minute C: .the mistake of the railroad industry D: the history of New York commuter trains
