Example Input: Article: British writer John Bunyan was born at Elstow, Bedfordshire, England, in November, 1628. His father was a maker and mender of pots and kettles, and the son followed the same trade. Though he is usually called a tinker, Bunyan had a settled home and place of business. He had little schooling, and he describes his early surroundings as poor and mean. He became much interested in religions, but it was only after a tremendous spiritual conflict, lasting three or four years, that he found peace. His struggles are related with extraordinary vividness and intensity in his "Grace Abounding to the Chief of Sinners." His writing began with a controversy against the Quakers , and shows from the first the command of a homely but vigorous style. Like most working men at the time, Bunyan had a deep hatred for the corrupted, hypocritical rich who accumulated their wealth "by hook and by crook." As a stout Puritan , he had made a conscientious study of the Bible and firmly believed in salvation through spiritual struggle. Bunyan's style was modeled after that of the English Bible. With his concrete and living language and carefully observed and vividly presented details, he made it possible for the reader of the least education to share the pleasure of reading his novel and to relive the experience of his characters. Bunyan's works include Grace Abounding to the Chief of Sinners (1666), The Life and Death of Mr. Badman (1680), The Holy War (1682) and The Pilgrim's Progress (1684). The Pilgrim's Progress is the most successful religious allegory in the English language. Its purpose is to urge people to observe Christian doctrines and seek salvation through constant struggle with their own weaknesses and all kinds of social evils. It is not only about something spiritual but also bears much relevance to the time. Its predominant metaphor -- life as a journey -- is simple and familiar. The objects that Christian meets are homely and commonplace, and the scenes presented are typical English ones, but throughout the allegory a spiritual significance is added to the commonplace details. Here the strange is combined with the familiar and the trivial joined to the divine, and, a rich imagination and a natural talent for storytelling also contribute to the success of the work which is at once entertaining and morally instructive. "The Vanity Fair," is an excerpt from The Pilgrim's Progress. The story starts with a dream in which the author sees Christian the Pilgrim, with a heavy burden on his back, reading the Bible. When he learns from the book that the city in which he and his family live shall be burnt down in a fire, Christian tries to convince his family and his neighbors of the oncoming disaster and asks them to go with him in search of salvation, but most of them simply ignore him. So he starts off with a friend, Pliable. Pliable turns back after they stumble into a pit, the Slough of Despond. Christian struggles on by himself. Then he is misled by Mr. Wordly Wiseman and is brought back onto the right road by Mr. Evangelist. There he joins Faithful, a neighbor who has set out later but has made better progress. The two go on together through many adventures, including the great struggle with Apollyon, who claims them to be his subjects and refuse to accept their allegiance to God. After many other adventures they come to the Vanity Fair where both are arrested as alien agitators. They are tried and Faithful is condemned to death. Christian, however manages to escape and goes on his way, assisted by a new friend, Hopeful. Tired of the hard journey, they are tempted to take pleasant path and are then captured by Giant Despair. Finally they get away and reach the Celestial City, where they enjoy eternal life in the fellowship of the blessed.

Example Input: Article: -For five days, Edmonton's Downtown Park is transformed into one huge stage where artists are able to share their talents, and where people are able to celebrate and enjoy themselves. Since its beginning in 1980, the Edmonton Folk Music Festival has been commemorating the true feeling of what folk music is all about and that's the traditional togetherness that is felt when people gather to share stories and feelings through song. This year will be the sixth year when volunteer Riedel will be offering up her time to the festival. "People coming off a busy spring and summer have a moment of relaxation," Riedel said. "It's really easy to relax, and it's great seeing family and friends have fun together." These families and friends come from all different kinds of musical tastes. People who take pleasure in Blues are there, so are people who love Bluegrass. This festival does its best to develop everyone's musical interests. With so many years of experience, the festival has become a well-oiled machine, and does whatever it can to make attendees feel as comfortable as possible. There are free water stations throughout the venue for people to fill up their travel cups. When people buy food, reusable dishes are given a $2 plate fee, but that is returned when the plate is brought back. The festival has completely sold out of tickets, and in record time. But with big names such as Van Morrison and Jakob Dylan, it's easy to see how that was going to happen. There is no parking area during the festival, so using the Park & Ride system or Edmonton Transit is highly recommended. A bike lock-up area is provided and will be available Thursday until Sunday one hour before the gates open until 45 minutes after the gates close. The Edmonton Folk Music Festival begins on Wednesday, Aug. 4 with Van Morrison playing the special donation fund concert, and will finish up on Sunday, Aug. 8.

Example Input: Article: If cars had wings, they could fly and that just might happen, beginning in 2012.The company Terrafugia, based in Woburn, Massachusetts, says it plans to deliver its carplane, the Transition, to customers by the end of 2012. " It's the next 'wow' vehicle," said Terrafugia vice president Richard Gersh."Anybody can buy a Ferrari, but as we say, Ferraris don't fly." The car plane has wings that unfold for flying-a process the company says takes one minute-and fold back up for driving. A runway is still required to take off and land. The Transition is being marketed more as a plane that drives than a car that flies, although it is both.The company has been working with FAA to meet aircraft regulations, and with the National High way Traffic Safety Administration to meet vehicle safety regulations. The company is aiming to sell the Transition to private pilots as a more convenient and cheaper way to fly.They say it saves you the trouble of trying to find another mode of transportation to get to and from airports: You drive the car to the airport and then you're good to go.When you land, you fold up the wings and hit the road.There are no expensive parking fees because you don't have to store it at an air port-you park it in the garage at home. The carplane is designed to fly primarily under 10,000 feet.It has a maximum takeoff weight of 1,430 pounds, including fuel and passengers.Terrafugia says the Transition reduces the potential for an accident by allowing pilots to drive under bad weather instead of flying into marginal conditions. The Transition's price tag: $ 194,000.But there may be additional charges for options like a radio, transponder or GPS.Another option is a fullplane parachute. "If you get into a very awful situation, it is the necessary safety option,"Gersh said. So far, the company has more than 70 0rders with deposits. "We're working very closely with them, but there are still some remaining steps, " Brown said.
