As I understand it, the fact that you got the question wrong is what flags it as "Very High" priority. I believe that priority is factored into your analytics and helps the Virtual Tutor create drills that are more likely to address your weak points.

I don’t think that “usually” was explicitly listed as a quantifier anywhere, but just like the other word categories that we explored in the last section, I think it is fair to say that it is impossible to define a strict set of English quantifiers that is worth memorizing. It is more helpful to recognize the qualities of quantifiers we find “in the wild” and relate them to ones we already know.

In the case of “usually”, I would recognize that it means “most of the time” and proceed with my analysis based on that fact.
