tenant reports a leaking sink trap. What is the best first

B. Inspect the leak source and tighten or replace the trap
connections as needed
C. Shut off water to the entire building immediately
D. Ignore it because it is not an emergency

worker can make a minor repair safely and avoid unnecessary
disruption. Shutting off water to the entire building is an
overreaction to a localized issue.

**2. Which tool is most appropriate for tightening a loose faucet
nut in a confined space?**
A. Sledgehammer
B. Pry bar

**4. A tenant reports that a bathroom floor is wet after shower
use. Which condition is most likely?**
A. Roof leak
B. Failing tub caulking or shower curtain gap
C. Gas leak
D. Main drain collapse in all cases
**Correct answer:** B
**Rationale:** Water on a bathroom floor after shower use
commonly comes from splash or deteriorated sealing. A roof
leak would likely affect the ceiling, not just the floor.
