Example Input: proper question: What rive joins the Rhine in Duisburg?
disfluent question: What city umm I mean rive joins the Rhine in Duisburg?
context: Until the early 1980s, industry was a major source of water pollution. Although many plants and factories can be found along the Rhine up into Switzerland, it is along the Lower Rhine that the bulk of them are concentrated, as the river passes the major cities of Cologne, Dusseldorf and Duisburg. Duisburg is the home of Europe's largest inland port and functions as a hub to the sea ports of Rotterdam, Antwerp and Amsterdam. The Ruhr, which joins the Rhine in Duisburg, is nowadays a clean river, thanks to a combination of stricter environmental controls, a transition from heavy industry to light industry and cleanup measures, such as the reforestation of Slag and brownfields. The Ruhr currently provides the region with drinking water. It contributes 70 m3/s (2,500 cu ft/s) to the Rhine. Other rivers in the Ruhr Area, above all, the Emscher, still carry a considerable degree of pollution.

Example Input: proper question: Who was thought to have loved Tugh Temur?
disfluent question: Who was thought to have loved Ragibagh or no make that Tugh Temur?
context: When Yesun Temur died in Shangdu in 1328, Tugh Temur was recalled to Khanbaliq by the Qipchaq commander El Temur. He was installed as the emperor (Emperor Wenzong) in Khanbaliq, while Yesun Temur's son Ragibagh succeeded to the throne in Shangdu with the support of Yesun Temur's favorite retainer Dawlat Shah. Gaining support from princes and officers in Northern China and some other parts of the dynasty, Khanbaliq-based Tugh Temur eventually won the civil war against Ragibagh known as the War of the Two Capitals. Afterwards, Tugh Temur abdicated in favour of his brother Kusala, who was backed by Chagatai Khan Eljigidey, and announced Khanbaliq's intent to welcome him. However, Kusala suddenly died only four days after a banquet with Tugh Temur. He was supposedly killed with poison by El Temur, and Tugh Temur then remounted the throne. Tugh Temur also managed to send delegates to the western Mongol khanates such as Golden Horde and Ilkhanate to be accepted as the suzerain of Mongol world. However, he was mainly a puppet of the powerful official El Temur during his latter three-year reign. El Temur purged pro-Kusala officials and brought power to warlords, whose despotic rule clearly marked the decline of the dynasty.
