Which part of the ladder is raised or extended from the bed section?

• A. Rungs
• B. Fly
• C. Rail
• D. Butt

Answer: (B)

The part raised or extended from the bed section is the fly. In an extension ladder, the lower portion stays as the bed or base, and the upper portion that slides out is the fly (the extension section) used to gain height. The rungs are just the steps you climb, not the moving part. The rails are the side supports, and the butt is the bottom end that sits on the ground. When you raise the ladder, you extend the fly and engage the locking mechanism to hold it at the desired height.
