Problem: The Zipingpu Hydropower Plant (simplified Chinese: 紫坪铺水库; traditional Chinese: 紫坪鋪水庫) located 20 km east of the epicenter was damaged. A recent inspection indicated that the damage was less severe than initially feared, and it remains structurally stable and safe. The Tulong reservoir upstream is in danger of collapse. About 2,000 troops have been allocated to Zipingpu, trying to release the pressure through spillway. In total, 391 dams, most of them small, were reported damaged by the quake.
How many troops were allocated to Zipingpu?
The answer is the following: 2,000

Problem: Prince Hall Freemasonry exists because of the refusal of early American lodges to admit African-Americans. In 1775, an African-American named Prince Hall, along with fourteen other African-Americans, was initiated into a British military lodge with a warrant from the Grand Lodge of Ireland, having failed to obtain admission from the other lodges in Boston. When the military Lodge left North America, those fifteen men were given the authority to meet as a Lodge, but not to initiate Masons. In 1784, these individuals obtained a Warrant from the Premier Grand Lodge of England (GLE) and formed African Lodge, Number 459. When the UGLE was formed in 1813, all U.S.-based Lodges were stricken from their rolls – due largely to the War of 1812. Thus, separated from both UGLE and any concordantly recognised U.S. Grand Lodge, African Lodge re-titled itself as the African Lodge, Number 1 – and became a de facto "Grand Lodge" (this Lodge is not to be confused with the various Grand Lodges on the Continent of Africa). As with the rest of U.S. Freemasonry, Prince Hall Freemasonry soon grew and organised on a Grand Lodge system for each state.
What exists today because of the refusal of early American lodges to admit African Americans?
The answer is the following: Prince Hall Freemasonry

Problem: Innuendo was released in early 1991 with an eponymous number 1 UK hit and other charting singles including, "The Show Must Go On". Mercury was increasingly ill and could barely walk when the band recorded "The Show Must Go On" in 1990. Because of this, May had concerns about whether he was physically capable of singing it. Recalling Mercury's successful performance May states; "he went in and killed it, completely lacerated that vocal". The rest of the band were ready to record when Mercury felt able to come in to the studio, for an hour or two at a time. May says of Mercury: “He just kept saying. 'Write me more. Write me stuff. I want to just sing this and do it and when I am gone you can finish it off.’ He had no fear, really.” The band's second greatest hits compilation, Greatest Hits II, followed in October 1991, which is the eighth best-selling album of all time in the UK and has sold 16 million copies worldwide.
What was one single from Queen's Innuendo that charted in the UK?
