Problem: London:

London's first and only cable car, known as the Emirates Air Line, opened in June 2012. Crossing the River Thames, linking Greenwich Peninsula and the Royal Docks in the east of the city, the cable car is integrated with London's Oyster Card ticketing system, although special fares are charged. Costing 60 million to build, it carries over 3,500 passengers every day, although this is very much lower than its capacity. Similar to the Santander Cycles bike hire scheme, the cable car is sponsored in a 10-year deal by the airline Emirates.

Peruvian Carnival incorporates elements of violence and reflects the urban violence in Peruvian society following the internal conflict in Peru. Traditionally, Peruvian Andean festivities were held on this period every year because it is the rainy season. It was already violent during the 19th century, but the government limited the practice. During the early 20th century it consisted partying and parading, while in the second half of the 20th century it acquired violent characteristics that continued. It was banned, first from the streets in 1958 and altogether in 1959 by the Prado government. It consisted basically of water battles in a traditional way,[clarification needed] while in later years it included playing with dirty water, mud, oil and colorants -and also including fighting and sometimes looting private property and sexual assaults on women. It has become an excuse for criminal gangs to rob people while pretending to celebrate. As of 2010, it had become so violent that the government imposed penalties of up to eight years in prison for violence during the games (the games themselves are not forbidden, but using violence during the games or coercing others to participate is).
How many years in prison can someone expect for being violent during the fun and games?
A: eight

Question: Although used in the Census and the American Community Survey, "Some other race" is not an official race, and the Bureau considered eliminating it prior to the 2000 Census. As the 2010 census form did not contain the question titled "Ancestry" found in prior censuses, there were campaigns to get non-Hispanic West Indian Americans, Turkish Americans, Armenian Americans, Arab Americans and Iranian Americans to indicate their ethnic or national background through the race question, specifically the "Some other race" category.
Is there an answer to this question: There were campaigns to try to get minorities to use what race category into 2010 census?
