A feature measuring 20 inches high is classified as what?

• A. No
• B. Yes
• C. Only if slope present
• D. Only if wide

Answer: (C)

In this kind of assessment, how you classify a feature often depends on whether there is slope. A measurement of height by itself doesn’t automatically place the feature into a specific category; you need to know if there’s slope present to determine if that height creates a hazardous slope feature or a different classification. So a feature that’s 20 inches high is not automatically labeled one way or another unless you also know whether there’s slope. If there is slope, that height can trigger the specific slope-related classification; if there isn’t slope, that same height doesn’t meet those slope-based criteria.

That’s why the best choice is the one that says you classify it only if slope is present. The other options imply a definite classification regardless of slope or rely on other factors like width, which aren’t the gating condition for this scenario.
