B. Verbal or Non-verbal. Verbal concepts are those that use language to explain them. Verbal concepts are described by using words. Examples are concepts of love, democracy, or politeness. Non-verbal concepts are those that lend themselves to be best understood by being pictured or visualized.
Examples are concepts of a circle, proportions, or evaporation.
Many times both verbal and non-verbal concepts can be used to explain something. Sometimes a person may prefer one over the other. It is a good idea to try to think about a concept both by picturing it and by putting it into words. This will give you a more thorough understanding of the concept. Process concepts are those that explain how things happen or work.
