input: Make use of the article to answer the questions. The Dupont Circle park in Washington DC is a busy, crowded place. Popular restaurants and businesses around the circle attract many city residents and visitors. But few people know about the old streetcar station below the street. Braulio Agnese is the Managing Director of an organization called Dupont Underground. The group wants to change the old station into a place for the arts."We see everything from site-specific art work, which fills the space in different ways, light and sound or appliances. Or it can be used like a traditional gallery. But also as a curved space, it offers a chance for new kinds of performance. DC has quite a few experimental theater groups that would like to work in an unusual space and do different kinds of production."

The system of tunnels was built in the late 1940s. But the streetcars only ran for a short time. They stopped running in the 1960s. Mr. Agnese says the station could become a symbol of how quickly Washington is changing."Changes in the last five or ten years have been tremendous. The restaurant scene is changing, new development, new opportunities. We think there is an opportunity to create something here that helps the city to move forward."

Dupont Underground is just one example of the trend toward giving a new purpose to unused industrial sites. In New York, builders want to make a forgotten street car garage into a park below the street. And New York already has the popular High Line Park. It was once an old railroad path. The question is -- can Dupont Underground be as successful?

Bill McLeod is Executive Director of Historic DuPont Circle Main Streets. The group helps small businesses in the DuPont Circle area. Mr. McLeod says the underground will fill a need in the area."I think there is definitely need for art space, or event space, in DuPont. And I think that will be the perfect space to activate because it's very large - it's 75 thousand square feet. Very cool, right?"

Another organization tried to open a group of eating places in the space 15 years ago. That food court project failed. Mr. McLeod says the group leading the new effort has a better understanding of the project. He says the group knows it will take a lot of time and money and is successfully seeking financial support. Braulio Agnese and his co-workers hope to open the underground station to the public in the next few months. 1. Where is Dupont Circle?

input: Make use of the article to answer the questions. Christmas is an annual festival commemorating the birth of Jesus Christ, observed most commonly on December 25 as a religious and cultural celebration among billions of people around the world. A feast central to the Christian liturgical year, it is prepared for by the season of Advent or the Nativity Fast and initiates the season of Christmastide, which historically in the West lasts twelve days and culminates on Twelfth Night; in some traditions, Christmastide includes an Octave. The traditional Christmas narrative, the Nativity of Jesus, delineated in the New Testament says that Jesus was born in Bethlehem, in accordance with messianic prophecies; when Joseph and Mary arrived in the city, the inn had no room and so they were offered a stable where the Christ Child was soon born, with angels proclaiming this news to shepherds who then disseminated the message furthermore. Christmas Day is a public holiday in many of the world's nations, is celebrated religiously by the vast majority of Christians, as well as culturally by a number of non-Christian people, and is an integral part of the holiday season, while some Christian groups reject the celebration. In several countries, celebrating Christmas Eve on December 24 has the main focus rather than December 25, with gift-giving and sharing a traditional meal with the family. 1. what holiday occurs on Dec 25?
