In this task, you're given a question, along with a context passage which has extra information available on certain terms mentioned in it. Your job is to determine which sentence(s) from the passage can be used to search for further information needed to answer the question.

Input: Consider Input: Question: Where was Billboard Frolics' creator born? Passage:Cantor appears in caricature form in numerous Looney Tunes cartoons produced for Warner Bros., although he was often voiced by an imitator. Beginning with I Like Mountain Music (1933), other animated Cantor cameos include Shuffle Off to Buffalo (Harman-Ising, 1933) and Billboard Frolics (Friz Freleng, 1935). Eddie Cantor is one of the four "down on their luck" stars (along with Bing Crosby, Al Jolson, and Jack Benny) snubbed by Elmer Fudd in What's Up, Doc? (Bob McKimson, 1950). In Farm Frolics (Bob Clampett, 1941), a horse, asked by the narrator to "do a canter", promptly launches into a singing, dancing, eye-rolling impression. The Cantor gag that got the most mileage, however, was his oft-repeated wish for a son after five famous daughters. Slap-Happy Pappy (Clampett, 1940) features an "Eddie Cackler" rooster that wants a boy, to little avail. Other references can be found in Baby Bottleneck (Clampett, 1946) and Circus Today (Tex Avery, 1940). In Merrie Melodies, The Coo-Coo Nut Grove Cantor's many daughters are referenced by a group of singing quintuplet girls. In Porky's Naughty Nephew (Clampett, 1938) a swimming Cantor gleefully adopts a "buoy". An animated Cantor also appears prominently in Walt Disney's "Mother Goose Goes Hollywood" (Wilfred Jackson, 1938) as Little Jack Horner, who sings "Sing a Song of Sixpence".

Output: Beginning with I Like Mountain Music (1933), other animated Cantor cameos include Shuffle Off to Buffalo (Harman-Ising, 1933) and Billboard Frolics (Friz Freleng, 1935)

Input: Consider Input: Question: Which North American city hall building that used Superblocks was completed first? Passage:Superblocks are also used when functional units such as rail yards or shipyards, inherited from the 19th and early 20th centuries, are too big to fit in an average city block. A contemporary function which reflects ancient practices that also requires larger than typical blocks is the sports stadium or arena. Just as the Colosseum in ancient Rome, sports complexes require superblocks. The Providence Park stadium in Portland, for example, takes up four normal city blocks as does the equally large Greensboro Coliseum in North Carolina. Other contemporary institutions, establishments or functions that use superblocks are: city halls like Government Center, Boston and Toronto City Hall; regional general hospitals or specialized medical centres; convention and exhibition centers, such as Exhibition Place in Toronto and the Boston Convention and Exhibition Center; and downtown enclosed Shopping Malls such as Eaton Centre in Toronto, echoing the large gallerias of the 19th century. Cultural complexes, such as the Lincoln Center in New York City, often occupy a superblock achieved through the consolidation of regular city blocks. A recent superblock user is the merchandise distribution centre, which can range in area from one to ten city blocks.

Output: Other contemporary institutions, establishments or functions that use superblocks are: city halls like Government Center, Boston and Toronto City Hall; regional general hospitals or specialized medical centres; convention and exhibition centers, such as Exhibition Place in Toronto and the Boston Convention and Exhibition Center; and downtown enclosed Shopping Malls such as Eaton Centre in Toronto, echoing the large gallerias of the 19th century

Input: Consider Input: Question: Where was Hugh Percy's wife born? Passage:He changed his surname to Percy when he married Lady Elizabeth Seymour (17161776), daughter of His Grace The 7th Duke of Somerset, on 16 July 1740, through a private Act of Parliament. She was Baroness Percy in her own right, and indirect heiress of the Percy family, which was one of the leading landowning families of England and had previously held the Earldom of Northumberland for several centuries. The title Earl of Northumberland passed by special remainder to Hugh Percy, as Elizabeth's husband, when her father died on 7 February 1750; he had been created 1st Earl of Northumberland in 1749. In 1766, the earl was created 1st Duke of Northumberland and was created Baron Lovaine on 28 June 1784, with a special remainder in favour of his younger son, Algernon. (The Louvain family of the Landgraviate of Brabant, which married the Percy heiress, was the origin of the Percy family of England). Richard de Percy, 5th Baron Percy (c. 11701244) (who adopted the surname Percy), was the son of Joscelin of Louvain (11211180), styled "brother of the queen" (referring to Adeliza of Louvain, second wife of King Henry I of England, by his wife Agnes de Perci, suo jure Baroness Percy, the heiress of the Percy estates in England.) He was created a Knight of the Order of the Garter in 1756 and a Privy Counsellor in 1762.
Output: He changed his surname to Percy when he married Lady Elizabeth Seymour (17161776), daughter of His Grace The 7th Duke of Somerset, on 16 July 1740, through a private Act of Parliament
