A parapet is defined as which of the following?

• A. A decorative feature around windows
• B. Portion of exterior walls that extends above the roof
• C. A rain gutter
• D. A curved roof support

Answer: (B)

The key idea is understanding what a parapet is in building construction. A parapet is a portion of exterior walls that extends above the roofline. This definition matters because parapets are wall sections that protrude past the roof edge, not decorative features, gutters, or structural roof supports. The other options describe features that aren’t wall extensions above the roof: a decorative surround around windows, a rain gutter along the roof edge, and a curved roof support. So the correct understanding is that a parapet is the wall portion that rises above the roof.
