Question: What were the combined ages of Sabrina Washington and Alesha Dixon the year that they met at Dance Attic studios? Passage 1:He was born on 29 August 1874 in Athens, where he spent his childhood. In September 1891 he went to Paris for the first time to study at Lycee Janson-de-Sailly, preparing for the French Naval School and pursuing a military career. His guardian during that time was Dimitrios Vikelas. However, in June 1893 he failed the Naval School exams and in October of the same year he enrolled at the Sorbonne Law School. In the summer of 1896 he was in Munich to study law at the University of Ludwig-Maximilans, while at the same time he became friend with the painter Dimitrios Geraniotis, who studied at the Munich Academy. In November 1897, Nikos Dragoumis obtained his degree from the University of Sorbonne and returned to Greece to pursue a career in the Foreign Ministry. However, he broke up with his family and his father, Stephanos, sent him to Volos to work as an assistant manager of the Thessaly Railway Company. But Nikos Dragoumis secretly left Volos in May 1899 and returned to Paris this time to study painting.
Passage 2:The peak of rail freight came during World War II, when New York industries, including the Brooklyn Navy Yard, worked around the clock to support the war effort. After the war, the Interstate Highway System was built, along with many inland waterways, both competing with the railroads. The rail industry went through widespread consolidations and bankruptcies. Containerization revolutionized shipping. The Port Authority developed the Port Newark-Elizabeth Marine Terminal on Newark Bay. Piers in Brooklyin and Manhattan declined in usage and were abandoned. The 1980 Staggers Rail Act largely deregulated the U.S. railroads. The railroads de-emphasized "retail" railroadingmovement of one or a few rail cars from a shipper's siding to a destination sidingin favor of long unit trains for bulk commodities, such as coal and ore. General cargo shifted to intermodal movement, first trailers on flat cars (TOFC), intermodal containers on flat cars (COFC), and then double-stacked containers, loaded on special well cars. Much manufacturing shifted to Asia, particularly Japan and China, leading to a sharp increase in international container movements.
Passage 3:Alesha Dixon and Sabrina Washington met in 1997 at Dance Attic studios in Fulham through Louise Porter, who was putting together a group for her production company Big Out Ltd. The two worked with Louise Porter for a couple of years before being joined by Tina Barrett to form a trio performing singing and dancing. They were named Face2Face, were unsigned, and all band members still worked day jobs. Barrett left to join S Club 7 after a successful audition for Simon Fuller and was replaced by Zena McNally and Su-Elise Nash. Their then producer David Brant (writer of their first two hit singles, "Why?" and "All I Want") introduced them via DJ Darren Stokes (TinTinOut) to Inferno Records (sub pop) A&R man Pat Travers, who went on to sign them to Telstar Records and changed their name to Mis-Teeq. After months of recordingincluding sessions with producers Norwegian duo Stargate along with Brant (Vybrant Music), Ed Case, Blacksmith, Rishi Rich, and Ceri EvansMis-Teeq released their debut single in 2000, "Why?", a Latin-flavoured mid-tempo song co-written and produced by Brant. A garage remix by Matt "Jam" Lamont soon became a success in the underground UK garage scene, and as a result a second music video for the song was filmed and released. "Why" became a hit on the UK Singles Chart with a peak position of number eight. McNally decided to leave the line-up in spring 2001 saying she felt unhappy about "an unbalance in the group".
