What is the primary characteristic of a soft story in a building?
- It lacks commercial areas or large openings on any floor.
- It contains multiple shear walls for added stability.
- It has a rigid structure capable of withstanding lateral loads.
- It has one or more levels that are significantly weaker against lateral forces. (correct)
