Which term means 'downward measurement'?

• A. Deteriorating
• B. Depth
• C. Constrict
• D. Contingent

Answer: (B)

Depth is the term that means downward measurement. It describes how far something extends from a surface toward the bottom, capturing vertical extent in a downward direction. For example, you talk about the depth of water in a pool, which is how deep the water goes from surface to bottom.

The other words refer to different ideas: deteriorating means getting worse over time, not a directional measurement; constrict means to make something tighter or narrower; contingent means dependent on something else. None of these convey the idea of measuring downward from a surface like depth does.
