The correct response to the difference between a mass extinction and a regular (background) extinction is:
**Mass extinction involves many species over a short period of geologic time.**
This captures the key distinction, as mass extinctions are characterized by a significant loss of biodiversity across numerous taxa in a relatively brief timespan, whereas background extinctions occur at a more gradual rate and typically affect fewer species.
