___________

1. We have no idea. The sponges may have lived before and after the Jurassic.
2. Same as A. We have no idea how common sponges were in other eras.
3. CORRECT. If this weren’t true then those sponges couldn’t have been “widespread.” They only do well in slow-moving waters.
4. We have no idea where other types of sponges can live.
5. We don’t know. The stimulus doesn’t tell us this.
