PROBLEM: Article: You can have your adventure and eat too at Europe's first green restaurant where traditional German food is served in a beautifully lit wooden hilltop restaurant powered by solar energy at a height of 1,025 metres among tall trees in the Black Forest. The Rappenecker Hutte is a 350-year-old farm house in south Germany which has been serving as a hikers' restaurant for several years. It was the starting point of the downhill course of the Mountain Bike World Championship (MBWC) in 1995 and is a well-known station of the Black Forest Ultra Bike Marathon (BFUBM). "People come here for adventure trips, mountain biking or hiking and stop for traditional German food. We produce all our energy from renewable sources as it is very expensive to get a power grid connection at this site," said Dirk Behringer, owner of the Rappenecker Hutte. Like the restaurant, the story of its present owner is equally amazing as Behringer, 57, left his well-paid job in 2003 to stay here with his wife. "I have traveled across the world and as I was growing old I realized I wanted to retire and live in nature. So I rented the restaurant. Since then I, along with my wife, live here in summer and we travel during winter," said the six-foot-tall man dressed in a T-shirt and shorts. Due to heavy snow during winter, the restaurant opens only for six months from April to September when it receives around 500 guests per week. The Behringer couple has employed no helper and does everything from cooking to cleaning at this hilltop restaurant which gives a picturesque view of the Black Forest. There are not many dishes on the menu for unexpected visitors. On a routine basis, there is one vegetarian dish which includes fried potatoes with dense milk cream, boiled vegetables and fresh salad. The non-vegetarian dish includes fried potatoes with pork and salad. There are also options to pick from fresh juices, hard drinks and coffee. All vegetables, fruits, dairy products and meat supplies to the restaurant come from farms in nearby villages.

Options: (A) prove the restaurant has a long history (B) advise us to do more exercise (C) stress the restaurant's being unusual (D) express his fondness of the restaurant

PROBLEM: Article: For most people,below--freezing temperatures generally put a stop to outdoor exercise,but Siberian native Boris Fyodorov is not most people. Minutes after the calendar ticked over to this past 2014 New Year's Eve,Fyodorov set off on a solo,out--and--back marathon run from his home in the Siberian village of Oymyakon,completing the 26.2-mile course-his first marathon-in just over five hours.During the run he experienced temperatures as low as -38oC. And that was just the way he wanted it. "I heard about other marathons around the globe,naming themselves 'the coldest',like the most recent North Pole marathon with runners going at -28oC.'' Fyodorov told the Siberian Times."I thought surely this cannot be right.Our Oymyakon is the coldest inhabited place in northern hemisphere.Why don't we arrange a marathon here?'' Oymyakon is widely considered to be one of the coldest places on the planet,and its record-low temperature of-68oC, recorded in 1933,is tied for the coldest recorded temperature for any inhabited place on Earth.The average January temperature in the area is -50oC. Not only did Fyodorov finish the marathon in high spirits,but he also wants it to be colder the next time he tries it."I really want to organize next Oymyakon marathon in January when the air goes down to -50oC or -60oC,"he said. Fyodorov is not the first person to take on a cold--weather athletic challenge like this.In addition to the North Pole Marathon that he mentioned,the Antarctica Marathon is held every year in late February,taking runners on an out--and--back tour from Russia's Bellingshausen Station.A second Antarctica event--the Ice Marathon--has been held80F degrees south since 2006.
