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.

[Q]: proper question: How many vector equations did Heaviside and Gibbs reformilate Maxwell's 20 scalar equtions into? 
 disfluent question: How many fields no vector equations did Heaviside and Gibbs reformulate Maxwell's 20 scalar equations into? 
 context: The origin of electric and magnetic fields would not be fully explained until 1864 when James Clerk Maxwell unified a number of earlier theories into a set of 20 scalar equations, which were later reformulated into 4 vector equations by Oliver Heaviside and Josiah Willard Gibbs. These Maxwell Equations fully described the sources of the fields as being stationary and moving charges, and the interactions of the fields themselves. This led Maxwell to discover that electric and magnetic fields could be self-generating through a wave that traveled at a speed that he calculated to be the speed of light. This insight united the nascent fields of electromagnetic theory with optics and led directly to a complete description of the electromagnetic spectrum.
[A]: Yes


[Q]: proper question: Where can Aeolian sand with a number of dunes be found? 
 disfluent question: What type er where can Aeolian sand with a number of dunes be found? 
 context: The plain moraine plateau has only a few natural and artificial ponds and also groups of clay pits. The pattern of the Vistula terraces is asymmetrical. The left side consist mainly of two levels: the highest one contains former flooded terraces and the lowest one the flood plain terrace. The contemporary flooded terrace still has visible valleys and ground depressions with water systems coming from the Vistula old – riverbed. They consist of still quite natural streams and lakes as well as the pattern of drainage ditches. The right side of Warsaw has a different pattern of geomorphological forms. There are several levels of the plain Vistula terraces (flooded as well as former flooded once) and only small part and not so visible moraine escarpment. Aeolian sand with a number of dunes parted by peat swamps or small ponds cover the highest terrace. These are mainly forested areas (pine forest).
[A]: Yes


[Q]: proper question: Residential construction practices, technologies, and resources must conform to what? 
 disfluent question: Residential construction waste sorry no practices, technologies, and resources must conform to what? 
 context: Residential construction practices, technologies, and resources must conform to local building authority regulations and codes of practice. Materials readily available in the area generally dictate the construction materials used (e.g. brick versus stone, versus timber). Cost of construction on a per square meter (or per square foot) basis for houses can vary dramatically based on site conditions, local regulations, economies of scale (custom designed homes are often more expensive to build) and the availability of skilled tradespeople. As residential construction (as well as all other types of construction) can generate a lot of waste, careful planning again is needed here.
[A]:
Yes
