London's buildings are too diverse to be characterised by any particular architectural style, partly because of their varying ages. Many grand houses and public buildings, such as the National Gallery, are constructed from Portland stone. Some areas of the city, particularly those just west of the centre, are characterised by white stucco or whitewashed buildings. Few structures in central London pre-date the Great Fire of 1666, these being a few trace Roman remains, the Tower of London and a few scattered Tudor survivors in the City. Further out is, for example, the Tudor period Hampton Court Palace, England's oldest surviving Tudor palace, built by Cardinal Thomas Wolsey c.1515.
What, in part, is the reason for London's lack of a singularly characteristic architectural style among its buildings?
their varying ages

New York has been described as the "Capital of Baseball". There have been 35 Major League Baseball World Series and 73 pennants won by New York teams. It is one of only five metro areas (Los Angeles, Chicago, BaltimoreWashington, and the San Francisco Bay Area being the others) to have two baseball teams. Additionally, there have been 14 World Series in which two New York City teams played each other, known as a Subway Series and occurring most recently in 2000. No other metropolitan area has had this happen more than once (Chicago in 1906, St. Louis in 1944, and the San Francisco Bay Area in 1989). The city's two current Major League Baseball teams are the New York Mets, who play at Citi Field in Queens, and the New York Yankees, who play at Yankee Stadium in the Bronx. who compete in six games of interleague play every regular season that has also come to be called the Subway Series. The Yankees have won a record 27 championships, while the Mets have won the World Series twice. The city also was once home to the Brooklyn Dodgers (now the Los Angeles Dodgers), who won the World Series once, and the New York Giants (now the San Francisco Giants), who won the World Series five times. Both teams moved to California in 1958. There are also two Minor League Baseball teams in the city, the Brooklyn Cyclones and Staten Island Yankees.
How many World Series have New York teams won?

The strength of beers has climbed during the later years of the 20th century. Vetter 33, a 10.5% abv (33 degrees Plato, hence Vetter "33") doppelbock, was listed in the 1994 Guinness Book of World Records as the strongest beer at that time, though Samichlaus, by the Swiss brewer Hurlimann, had also been listed by the Guinness Book of World Records as the strongest at 14% abv. Since then, some brewers have used champagne yeasts to increase the alcohol content of their beers. Samuel Adams reached 20% abv with Millennium, and then surpassed that amount to 25.6% abv with Utopias. The strongest beer brewed in Britain was Baz's Super Brew by Parish Brewery, a 23% abv beer. In September 2011, the Scottish brewery BrewDog produced Ghost Deer, which, at 28%, they claim to be the world's strongest beer produced by fermentation alone.
What do brewing companies sometimes use to give more alcohol content to their beer?
