Definition: 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.
Input: proper question: What notion causes one to deal with classical variables instead of operators? 
 disfluent question: What notion causes one to deal with operators no classical variables instead of operators? 
 context: The notion force keeps its meaning in quantum mechanics, though one is now dealing with operators instead of classical variables and though the physics is now described by the Schrödinger equation instead of Newtonian equations. This has the consequence that the results of a measurement are now sometimes quantized, i.e. they appear in discrete portions. This is, of course, difficult to imagine in the context of forces. However, the potentials V(x,y,z) or fields, from which the forces generally can be derived, are treated similar to classical position variables, i.e., .
