QUES: Under the supervision of May and Taylor, numerous restoration projects have been under way involving Queen's lengthy audio and video catalogue. DVD releases of their 1986 Wembley concert (titled Live at Wembley Stadium), 1982 Milton Keynes concert (Queen on Fire – Live at the Bowl), and two Greatest Video Hits (Volumes 1 and 2, spanning the 1970s and 1980s) have seen the band's music remixed into 5.1 and DTS surround sound. So far, only two of the band's albums, A Night at the Opera and The Game, have been fully remixed into high-resolution multichannel surround on DVD-Audio. A Night at the Opera was re-released with some revised 5.1 mixes and accompanying videos in 2005 for the 30th anniversary of the album's original release (CD+DVD-Video set). In 2007, a Blu-ray edition of Queen's previously released concerts, Queen Rock Montreal & Live Aid, was released, marking their first project in 1080p HD.

QUES: Colonial records of French and Spanish slave ships and sales, and plantation records in all the former colonies, often have much more information about slaves, from which researchers are reconstructing slave family histories. Genealogists have begun to find plantation records, court records, land deeds and other sources to trace African-American families and individuals before 1870. As slaves were generally forbidden to learn to read and write, black families passed along oral histories, which have had great persistence. Similarly, Native Americans did not generally learn to read and write English, although some did in the nineteenth century. Until 1930, census enumerators used the terms free people of color and mulatto to classify people of apparent mixed race. When those terms were dropped, as a result of the lobbying by the Southern Congressional bloc, the Census Bureau used only the binary classifications of black or white, as was typical in segregated southern states.
Who caused the Census Burea to drop the terms free people of color and mulatto?

ANS: Southern Congressional bloc


In Sand Springs, an outdoor amphitheater called "Discoveryland!" is the official performance headquarters for the musical Oklahoma! Ridge Bond, native of McAlester, Oklahoma, starred in the Broadway and International touring productions of Oklahoma!, playing the role of "Curly McClain" in more than 2,600 performances. In 1953 he was featured along with the Oklahoma! cast on a CBS Omnibus television broadcast. Bond was instrumental in the title song becoming the Oklahoma state song and is also featured on the U.S. postage stamp commemorating the musical's 50th anniversary. Historically, the state has produced musical styles such as The Tulsa Sound and western swing, which was popularized at Cain's Ballroom in Tulsa. The building, known as the "Carnegie Hall of Western Swing", served as the performance headquarters of Bob Wills and the Texas Playboys during the 1930s. Stillwater is known as the epicenter of Red Dirt music, the best-known proponent of which is the late Bob Childers.

Ah, so.. more than 2,600


Question: Neoclassical architecture was introduced in Malta in the late 18th century, during the final years of Hospitaller rule. Early examples include the Bibliotheca (1786), the De Rohan Arch (1798) and the Hompesch Gate (1801). However, neoclassical architecture only became popular in Malta following the establishment of British rule in the early 19th century. In 1814, a neoclassical portico decorated with the British coat of arms was added to the Main Guard building so as to serve as a symbol of British Malta. Other 19th century neoclassical buildings include RNH Bighi (1832), St Paul's Pro-Cathedral (1844), the Rotunda of Mosta (1860) and the now destroyed Royal Opera House (1866).
Try to answer this question if possible: In what year did the St Paul's Pro-Cathedral get built?
