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.

Ex 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]

Ex Output:
No


Ex Input:
proper question: Why has the Muslim Brotherhood not facilitated inexpensive mass marriage ceremonies? 
 disfluent question: How, sorry, why has the Muslim Brotherhood not facilitated inexpensive mass marriage ceremonies? 
 context: Islamist movements such as the Muslim Brotherhood, are well known for providing shelters, educational assistance, free or low cost medical clinics, housing assistance to students from out of town, student advisory groups, facilitation of inexpensive mass marriage ceremonies to avoid prohibitively costly dowry demands, legal assistance, sports facilities, and women's groups. All this compares very favourably against incompetent, inefficient, or neglectful governments whose commitment to social justice is limited to rhetoric.

Ex Output:
No


Ex Input:
proper question: In what year did the Black Death reach the Mediterranean? 
 disfluent question: Where did the black death reach no no when did the Black Death reach the Mediterranean shores? 
 context: The Black Death is thought to have originated in the arid plains of Central Asia, where it then travelled along the Silk Road, reaching Crimea by 1343. From there, it was most likely carried by Oriental rat fleas living on the black rats that were regular passengers on merchant ships. Spreading throughout the Mediterranean and Europe, the Black Death is estimated to have killed 30–60% of Europe's total population. In total, the plague reduced the world population from an estimated 450 million down to 350–375 million in the 14th century. The world population as a whole did not recover to pre-plague levels until the 17th century. The plague recurred occasionally in Europe until the 19th century.
