Could you tell me how to determine the complexity of a category? What is the method? Such as "run" is specific and "take" is confusable. Thank you !

Each activity in Charades consists of (noun,verb,proposition) where noun and proposition can be "None". Verb complexity is calculated by asking "How many activities (categories) in Charades have this same verb?" Take, for example, includes "take cup" "take dish" "take picture" etc, but run only includes "Running somewhere". That is, this is a measure of how many activities can be confused based on the verb. The verb complexity of an activity is the verb complexity of the verb in that activity.

Does that clarify it?
