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 did Alexandre Yersin discover the Yersinia pestis? 
 disfluent question: In what year did Paul-Louis er uh Alexandre Yersin discover the Yersinia pestis? 
 context: The dominant explanation for the Black Death is the plague theory, which attributes the outbreak to Yersinia pestis, also responsible for an epidemic that began in southern China in 1865, eventually spreading to India. The investigation of the pathogen that caused the 19th-century plague was begun by teams of scientists who visited Hong Kong in 1894, among whom was the French-Swiss bacteriologist Alexandre Yersin, after whom the pathogen was named Yersinia pestis. The mechanism by which Y. pestis was usually transmitted was established in 1898 by Paul-Louis Simond and was found to involve the bites of fleas whose midguts had become obstructed by replicating Y. pestis several days after feeding on an infected host. This blockage results in starvation and aggressive feeding behaviour by the fleas, which repeatedly attempt to clear their blockage by regurgitation, resulting in thousands of plague bacteria being flushed into the feeding site, infecting the host. The bubonic plague mechanism was also dependent on two populations of rodents: one resistant to the disease, which act as hosts, keeping the disease endemic, and a second that lack resistance. When the second population dies, the fleas move on to other hosts, including people, thus creating a human epidemic.

Ex Output:
No


Ex Input:
proper question: Who is the university accredited by? 
 disfluent question: How many or uh who is the university accredited by? 
 context: The academic bodies of the University of Chicago consist of the College, four divisions of graduate research and seven professional schools. The university also contains a library system, the University of Chicago Press, the University of Chicago Laboratory Schools, and the University of Chicago Medical Center, and holds ties with a number of independent academic institutions, including Fermilab, Argonne National Laboratory, and the Marine Biological Laboratory. The university is accredited by The Higher Learning Commission.

Ex Output:
Yes


Ex Input:
proper question: What happens in a phase 2 contract? 
 disfluent question: What happens in a phase 1 or no make that in a phase 2 contract? 
 context: The owner produces a list of requirements for a project, giving an overall view of the project's goals. Several D&B contractors present different ideas about how to accomplish these goals. The owner selects the ideas he or she likes best and hires the appropriate contractor. Often, it is not just one contractor, but a consortium of several contractors working together. Once these have been hired, they begin building the first phase of the project. As they build phase 1, they design phase 2. This is in contrast to a design-bid-build contract, where the project is completely designed by the owner, then bid on, then completed.

Ex Output:

No
