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.

Let me give you an 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.
The answer to this example can be: Yes
Here is 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.

OK. solve this:
proper question: Horizontal layers of what are pulled along a surface into a back stop in analog versions of orogenic wedge experiments? 
 disfluent question: Horizontal zones or uh layers of what are pulled along a surface into a back stop in analog versions of organic wedge experiments? 
 context: Among the most well-known experiments in structural geology are those involving orogenic wedges, which are zones in which mountains are built along convergent tectonic plate boundaries. In the analog versions of these experiments, horizontal layers of sand are pulled along a lower surface into a back stop, which results in realistic-looking patterns of faulting and the growth of a critically tapered (all angles remain the same) orogenic wedge. Numerical models work in the same way as these analog models, though they are often more sophisticated and can include patterns of erosion and uplift in the mountain belt. This helps to show the relationship between erosion and the shape of the mountain range. These studies can also give useful information about pathways for metamorphism through pressure, temperature, space, and time.
Answer:
Yes
