Question: Is the club Charles played against in 1883 still active? Passage:Educated at Wellington College and later attending Trinity Hall, Cambridge, Willock made a single first-class appearance for Cambridge University against the Marylebone Cricket Club at Fenner's in 1883. He was dismissed in Cambridge University's first-innings of 100 for a duck by Wilfred Flowers, while in the Marylebone Cricket Club's first-innings of 159 he took the wickets of Billy Gunn and Percy de Paravicini to finish with figures of 2/18 from 28 overs. In the University's second-innings of 65, he was once again dismissed for a duck by Flowers, while in the Marylebone Cricket Club's successful chase, he dismissed Gunn for a second time. Later that season he made a single first-class appearance for Sussex against Hamshire at Day's Antelope Ground. In Hampshire's first-innings of 110, he bowled ten wicketless overs which conceded 5 runs, while he ended Sussex's first-innings of 94 unbeaten on 8. In Hampshire's second-innings of 180, he bowled five wicketless overs which conceded 9 runs. In Sussex's second-innings of 165, he was dismissed for 6 runs by William Dible, with Hampshire winning the match by 31 runs.

Question: Did TJ Maxx make a profit the year Famous-Barr was re-branded as Macy's? Passage:Northpark Mall opened in 1972, on Range Line Road on the east side of Joplin. At the time, the mall was anchored by Montgomery Ward to the north, JCPenney to the south, and local chain Newman's the middle. Other stores included Walgreens, McCrory's, Ramsay's department store, For All Bible (which is still in business), Wyatts cafeteria, as well as many other stores. Newman's became Heer's in 1987, the same year that a new wing was built, and the mall received its first renovation. The new wing extended easterly from the JCPenney store. This new wing included two new anchors, Famous-Barr and Venture. The renovation also brought a food court as well as a new 5 screen cinema. In 1994, Heer's closed, and Famous-Barr moved its men's wear and home goods to the former Heer's space. That same year Sears built a store adjacent to Montgomery Ward, moving from an older store near downtown Joplin. In 1998 the mall received a minor renovation, changing only the color scheme. After the closure of the Venture chain in 1998, its anchor at the mall was converted to Shopko, but it closed in the early 2000s following the closure of Montgomery Ward in 2001. Both Famous-Barr locations were re-branded as Macy's in 2006. Montgomery Ward remained vacant until mid-2007, when its space was split between TJ Maxx and Steve & Barry's, the latter of which closed in 2008 and was replaced by Vintage Stock. In 2006 the mall received its first major renovation in nearly 20 years, changing the color scheme, adding all new lighting and floor tiles, and renovating the food court to a route 66 theme.

Question: How many scenes are there in Sullivan's successful ballet performed in 1897? Passage:When the Gilbert and Sullivan partnership collapsed after the production of The Gondoliers in 1889, their producer Richard D'Oyly Carte struggled to find successful new works to show at the Savoy Theatre. Carte produced Sullivan's grand opera, Ivanhoe at another theatre, and afterwards, he turned to Sullivan to create more comic operas for the Savoy. With Sydney Grundy, Sullivan wrote the nostalgic and sentimental Haddon Hall (1892) then, reunited with W. S. Gilbert, he produced Utopia, Limited (1893). He next returned, with his earlier collaborator F. C. Burnand, with The Chieftain (1894) and collaborated for the last time with Gilbert on The Grand Duke (1896). None of these had proved to be more than modestly successful, and Carte's other new pieces for the Savoy in the 1890s had done no better. Following the success of Sullivan's ballet Victoria and Merrie England in 1897, Carte asked Sullivan to work on another new opera for the Savoy.
