Extend a gun can flow water and be raised or lowered, but not in between. Which of the following is true?

Extend a gun can flow water and be raised or lowered, but not in between. Which of the following is true?

• A. Cannot determine
• B. False
• C. Not applicable
• D. True

Answer: (D)

The idea being tested is that some master-stream devices use discrete, two-position adjustments rather than a continuous range. In this kind of setup, the gun can be extended and then moved to either a raised or a lowered position, but there aren’t intermediate angles because mechanical stops or detents lock it into those two states. Water flow is controlled by the valve and can occur in either position; the important point is that the elevation has only two stable settings. So the statement is true because the design allows only two distinct elevations (raised or lowered) rather than a continuum of positions.
