Example Input: proper question: The 1989 Scottish Constitutional Convention provided very little basis for the structure of what?
disfluent question: The 1989 Scottish Constitutional Convention provided very little basis for the political parties structure of what?
context: Throughout the 1980s and 1990s, demand for a Scottish Parliament grew, in part because the government of the United Kingdom was controlled by the Conservative Party, while Scotland itself elected relatively few Conservative MPs. In the aftermath of the 1979 referendum defeat, the Campaign for a Scottish Assembly was initiated as a pressure group, leading to the 1989 Scottish Constitutional Convention with various organisations such as Scottish churches, political parties and representatives of industry taking part. Publishing its blueprint for devolution in 1995, the Convention provided much of the basis for the structure of the Parliament.
Example Output: No

Example Input: proper question: What banks are usually sparsely populated and lack industrialization?
disfluent question: Which towns no I guess river banks are usually sparsely populated and lack industrialization?
context: The Lower Rhine flows through North Rhine-Westphalia. Its banks are usually heavily populated and industrialized, in particular the agglomerations Cologne, Dusseldorf and Ruhr area. Here the Rhine flows through the largest conurbation in Germany, the Rhine-Ruhr region. One of the most important cities in this region is Duisburg with the largest river port in Europe (Duisport). The region downstream of Duisburg is more agricultural. In Wesel, 30 km downstream of Duisburg, is located the western end of the second east-west shipping route, the Wesel-Datteln Canal, which runs parallel to the Lippe.

Near Krefeld, the river crosses the Uerdingen line, the line which separates the areas where Low German and High German are spoken.
