In this task you are given a disfluent question, a proper question and a context. A disfluent question is a question that has some interruptions in it while framing and a proper question is the correct form of the question without any disfluency. Classify whether the question is answerable or not based on the given context.

Example Input: proper question: In what year was the Old Rhine Bridge shortened? 
 disfluent question: when was the Old Rhine Bridge shortened? 
 context: The length of the Rhine is conventionally measured in Rhine-kilometers (Rheinkilometer), a scale introduced in 1939 which runs from the Old Rhine Bridge at Constance (0 km) to Hoek van Holland (1036.20 km). The river length is significantly shortened from the river's natural course due to number of canalisation projects completed in the 19th and 20th century.[note 7] The total length of the Rhine, to the inclusion of Lake Constance and the Alpine Rhine is more difficult to measure objectively; it was cited as 1,232 kilometres (766 miles) by the Dutch Rijkswaterstaat in 2010.[note 1]
Example Output: No

Example Input: proper question: What type of ideals generalize Noetherian arithmetic? 
 disfluent question: What type of ideals generalize the Lasker Noether theorem, whoops I meant, the Noetherian arithmetic? 
 context: In ring theory, the notion of number is generally replaced with that of ideal. Prime ideals, which generalize prime elements in the sense that the principal ideal generated by a prime element is a prime ideal, are an important tool and object of study in commutative algebra, algebraic number theory and algebraic geometry. The prime ideals of the ring of integers are the ideals (0), (2), (3), (5), (7), (11), … The fundamental theorem of arithmetic generalizes to the Lasker–Noether theorem, which expresses every ideal in a Noetherian commutative ring as an intersection of primary ideals, which are the appropriate generalizations of prime powers.
Example Output: No

Example Input: proper question: What gang entered the West Side in 2008? 
 disfluent question: Which or no make that what gang entered the West Side in 2008? 
 context: The neighborhood includes Kearney Boulevard, named after early 20th century entrepreneur and millionaire M. Theo Kearney, which extends from Fresno Street in Southwest Fresno about 20 mi (32 km) west to Kerman, California. A small, two-lane rural road for most of its length, Kearney Boulevard is lined with tall palm trees. The roughly half-mile stretch of Kearney Boulevard between Fresno Street and Thorne Ave was at one time the preferred neighborhood for Fresno's elite African-American families. Another section, Brookhaven, on the southern edge of the West Side south of Jensen and west of Elm, was given the name by the Fresno City Council in an effort to revitalize the neighborhood's image. The isolated subdivision was for years known as the Dogg Pound in reference to a local gang, and as of late 2008 was still known for high levels of violent crime.
Example Output:
No
