Example Input: The expansion of what further cemented Houston's emergence as a powerhouse commercial city?, Context: By 1860, Houston had emerged as a commercial and railroad hub for the export of cotton. Railroad spurs from the Texas inland converged in Houston, where they met rail lines to the ports of Galveston and Beaumont. During the American Civil War, Houston served as a headquarters for General John Bankhead Magruder, who used the city as an organization point for the Battle of Galveston. After the Civil War, Houston businessmen initiated efforts to widen the city's extensive system of bayous so the city could accept more commerce between downtown and the nearby port of Galveston. By 1890, Houston was the railroad center of Texas.
Example Output: bayous

Example Input: Who can remove the plague?, Context: A number of non-Greek etymologies have been suggested for the name, The Hittite form Apaliunas (dx-ap-pa-li-u-na-as) is attested in the Manapa-Tarhunta letter, perhaps related to Hurrian (and certainly the Etruscan) Aplu, a god of plague, in turn likely from Akkadian Aplu Enlil meaning simply "the son of Enlil", a title that was given to the god Nergal, who was linked to Shamash, Babylonian god of the sun. The role of Apollo as god of plague is evident in the invocation of Apollo Smintheus ("mouse Apollo") by Chryses, the Trojan priest of Apollo, with the purpose of sending a plague against the Greeks (the reasoning behind a god of the plague becoming a god of healing is of course apotropaic, meaning that the god responsible for bringing the plague must be appeased in order to remove the plague).
Example Output: god of plague

Example Input: The founder of Bainbridges department store was born in what year?, Context: In 2010, Newcastle was positioned ninth in the retail centre expenditure league of the UK. There are several major shopping areas in Newcastle City Centre. The largest of these is the Eldon Square Shopping Centre, one of the largest city centre shopping complexes in the UK. It incorporates a flagship Debenhams store as well as one of the largest John Lewis stores in the UK. John Lewis is still known to many in Newcastle as Bainbridges. Newcastle store Bainbridge's, opened in 1838, is often cited as the world's first department store. Emerson Bainbridge (18171892), a pioneer and the founder of Bainbridges, sold goods via department, a new for merchant custom for that time. The Bainbridge's official ledgers reported revenue by department, giving birth to the name department store. Eldon Square is currently undergoing a full redevelopment. A new bus station, replacing the old underground bus station, was officially opened in March 2007. The wing of the centre, including the undercover Green Market, near Grainger Street was demolished in 2007 so that the area could be redeveloped. This was completed in February 2010 with the opening of a flagship Debenhams department store as well as other major stores including Apple, Hollister and Guess.
