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 Q]: proper question: When did the bubonic plague begin in Europe?
disfluent question: How did the or no rather when did the bubonic plague begin in Europe?
context: The historian Francis Aidan Gasquet wrote about the 'Great Pestilence' in 1893 and suggested that it would appear to be some form of the ordinary Eastern or bubonic plague. He was able to adopt the epidemiology of the bubonic plague for the Black Death for the second edition in 1908, implicating rats and fleas in the process, and his interpretation was widely accepted for other ancient and medieval epidemics, such as the Justinian plague that was prevalent in the Eastern Roman Empire from 541 to 700 CE.
[EX A]: No

[EX Q]: proper question: How high did the sea level rise during the ice ages?
disfluent question: How high did the northern part no the sea level rise during the ice ages?
context: Around 2.5 million years ago (ending 11,600 years ago) was the geological period of the Ice Ages. Since approximately 600,000 years ago, six major Ice Ages have occurred, in which sea level dropped 120 m (390 ft) and much of the continental margins became exposed. In the Early Pleistocene, the Rhine followed a course to the northwest, through the present North Sea. During the so-called Anglian glaciation (~450,000 yr BP, marine oxygen isotope stage 12), the northern part of the present North Sea was blocked by the ice and a large lake developed, that overflowed through the English Channel. This caused the Rhine's course to be diverted through the English Channel. Since then, during glacial times, the river mouth was located offshore of Brest, France and rivers, like the Thames and the Seine, became tributaries to the Rhine. During interglacials, when sea level rose to approximately the present level, the Rhine built deltas, in what is now the Netherlands.
[EX A]: No

[EX Q]: proper question: How many bits are often in the primes used for RSA private key cryptography algorithms?
disfluent question: How many bits are often in the exchange no primes used for RSA private key cryptography algorithms?
context: Several public-key cryptography algorithms, such as RSA and the DiffieHellman key exchange, are based on large prime numbers (for example, 512-bit primes are frequently used for RSA and 1024-bit primes are typical for DiffieHellman.). RSA relies on the assumption that it is much easier (i.e., more efficient) to perform the multiplication of two (large) numbers x and y than to calculate x and y (assumed coprime) if only the product xy is known. The DiffieHellman key exchange relies on the fact that there are efficient algorithms for modular exponentiation, while the reverse operation the discrete logarithm is thought to be a hard problem.
