You will be given a definition of a task first, then an example. Follow the example to solve a new instance of the task.
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.

proper question: Who recorded Walking in Fresno? 
 disfluent question: Where no sorry who recorded Walking in Fresno? 
 context: In the 1970s, the city was the subject of a song, Walking Into Fresno, written by Hall Of Fame guitarist Bill Aken and recorded by Bob Gallion of the world-famous WWVA Jamboree radio and television show in Wheeling, West Virginia. Aken, adopted by Mexican movie actress Lupe Mayorga, grew up in the neighboring town of Madera and his song chronicled the hardships faced by the migrant farm workers he saw as a child. Aken also made his first TV appearance playing guitar on the old country-western show at The Fresno Barn.
Solution: Yes
Why? The input sentence is correctly recognized as answerable or not because the answer to the question is 'Bill Aken' and it is present in the context so it is a positive example.

New input: proper question: When was the Rhine crisis? 
 disfluent question: Where rather when was the Rhine crisis? 
 context: Since the Peace of Westphalia, the Upper Rhine formed a contentious border between France and Germany. Establishing natural borders on the Rhine was a long-term goal of French foreign policy, since the Middle Ages, though the language border was – and is – far more to the west. French leaders, such as Louis XIV and Napoleon Bonaparte, tried with varying degrees of success to annex lands west of the Rhine. The Confederation of the Rhine was established by Napoleon, as a French client state, in 1806 and lasted until 1814, during which time it served as a significant source of resources and military manpower for the First French Empire. In 1840, the Rhine crisis, prompted by French prime minister Adolphe Thiers's desire to reinstate the Rhine as a natural border, led to a diplomatic crisis and a wave of nationalism in Germany.
