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.
One example: 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 is here: Yes
Explanation: 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.

Now, solve this: proper question: What does the name The Rhine come from?
disfluent question: Where, sorry, what does the name The Rhine come from?
context: The variant forms of the name of the Rhine in modern languages are all derived from the Gaulish name Renos, which was adapted in Roman-era geography (1st century BC) as Greek (Rhenos), Latin Rhenus.[note 3] The spelling with Rh- in English Rhine as well as in German Rhein and French Rhin is due to the influence of Greek orthography, while the vocalisation -i- is due to the Proto-Germanic adoption of the Gaulish name as *Rinaz, via Old Frankish giving Old English Rin, Old High German Rin, Dutch Rijn (formerly also spelled Rhijn)). The diphthong in modern German Rhein (also adopted in Romansh Rein, Rain) is a Central German development of the early modern period, the Alemannic name Ri(n) retaining the older vocalism,[note 4] as does Ripuarian Rhing, while Palatine has diphthongized Rhei, Rhoi. Spanish is with French in adopting the Germanic vocalism Rin-, while Italian, Occitan and Portuguese retain the Latin Ren-.
Solution:
Yes
