Answer the following question: Information: - The Varsity Match is an annual rugby union fixture played between the universities of Oxford and Cambridge in England. The event began in 1872, with interruptions only for the two World Wars. Since 1921, the game has been played at Twickenham Stadium, London. It is normally played in early December. - The University of Oxford (informally Oxford University or simply Oxford) is a collegiate research university located in Oxford, England, United Kingdom. While having no known date of foundation, there is evidence of teaching as far back as 1096, making it the oldest university in the English-speaking world and the world's second-oldest university in continuous operation. It grew rapidly from 1167 when Henry II banned English students from attending the University of Paris. After disputes between students and Oxford townsfolk in 1209, some academics fled northeast to Cambridge where they established what became the University of Cambridge. The two "ancient universities" are frequently jointly referred to as "Oxbridge". - The University of Paris, metonymically known as the Sorbonne (its historical house), was a university in Paris, France. Appearing around 1150 as a corporation associated with the Notre Dame de Paris cathedral school, it was the second-oldest modern university in Europe. Chartered in 1200 by King Philip II (Philippe-Auguste) of France and recognised in 1215 by Pope Innocent III, it was often nicknamed after its theology collegiate institution, College of Sorbonne, founded about 1257 by Robert de Sorbon. - The Oxford University Rugby Football Club ( Oxford University RFC or OURFC ) is the rugby union club of the University of Oxford .

More than half of these (231 million) live in the United States, followed by some 55 million in England, the first place where English was spoken. - England is a country that is part of the United Kingdom. It shares land borders with Scotland to the north and Wales to the west. The Irish Sea lies northwest of England and the Celtic Sea lies to the southwest. England is separated from continental Europe by the North Sea to the east and the English Channel to the south. The country covers five-eighths of the island of Great Britain (which lies in the North Atlantic) in its centre and south; and includes over 100 smaller islands such as the Isles of Scilly, and the Isle of Wight. - A team sport includes any sport which involves two or more players working together towards a shared objective.

With a population of 159,994 it is the 52nd largest city in the United Kingdom, and one of the fastest growing and most ethnically diverse. The city is situated from London, from Bristol, from both Southampton and Birmingham and from Reading. - London is the capital and most populous city of England and the United Kingdom, as well as the most populous city proper in the European Union. Standing on the River Thames in the south east of the island of Great Britain, London has been a major settlement for two millennia. It was founded by the Romans, who named it "Londinium". London's ancient core, the City of London, largely retains its medieval boundaries. Since at least the 19th century, "London" has also referred to the metropolis around this core, historically split between Middlesex, Essex, Surrey, Kent, and Hertfordshire, which today largely makes up Greater London, governed by the Mayor of London and the London Assembly. - Cambridge is a university city and the county town of Cambridgeshire, England, on the River Cam about north of London.

Other rugby union games played at the stadium include the Middlesex Sevens, the Aviva Premiership final, the LV Cup, the Varsity Match between the universities of Oxford and Cambridge, and European Rugby Champions Cup matches. The RFU headquarters are based in the stadium. - A try is a way of scoring points in rugby union and rugby league football. A try is scored by grounding the ball (the ball must be touching the player when coming into contact with the ground) in the opposition's in-goal area (on or behind the goal line). Rugby union and league differ slightly in defining 'grounding the ball' and the 'in-goal' area. - Rugby union, or simply rugby, is a contact team sport which originated in England in the first half of the 19th century.

Such universities can be recognized by their strong focus on innovative research and the prestige of their brand names. On the one hand, research universities strive to recruit faculty who are the most brilliant minds in their disciplines in the world, and their students enjoy the opportunity to learn from such experts. On the other hand, new students are often disappointed to realize their undergraduate courses at research universities are overly academic and fail to provide vocational training with immediate "real world" applications; but many employers value degrees from research universities because they know that such coursework develops fundamental skills like critical thinking.
