2. Which tool is BEST suited for tightening a hex bolt
A. Flathead screwdriver
B. Adjustable wrench
C. Needle-nose pliers
D. Hammer
Correct Answer: B ✓
Rationale: An adjustable wrench is designed for gripping and turning
hexagonal fasteners, ensuring proper torque and preventing damage.
3. A leaking pipe under a sink is most commonly caused by
A. Electrical failure
B. Loose fittings or worn washers
C. High voltage
D. Broken tiles
, Correct Answer: B ✓
Rationale: Leaks are typically due to loose connections or degraded
washers, both common in plumbing systems.
4. What is the purpose of a GFCI outlet
A. Increase voltage
B. Reduce lighting
C. Protect against electrical shock
D. Improve wiring speed
Correct Answer: C ✓
Rationale: A Ground Fault Circuit Interrupter (GFCI) detects imbalance in
current and shuts off power to prevent shock hazards.
5. When using a ladder, it should be placed at what angle
A. 90 degrees
B. 45 degrees
C. 75 degrees
D. 30 degrees
Correct Answer: C ✓
Rationale: The 4-to-1 rule establishes a safe ladder angle of approximately
75 degrees for stability.
6. A clogged drain is best cleared first using
A. Hammer
B. Plunger
C. Paintbrush
D. Saw
Correct Answer: B ✓
Rationale: A plunger uses pressure and suction to remove simple
blockages without damaging pipes.
7. Which material is commonly used for water supply pipes in modern
buildings

Correct Answer: B ✓
Rationale: The thermostat controls heating systems and is the first
diagnostic step.
12.Which tool measures electrical voltage
A. Multimeter
B. Hammer
C. Wrench
D. Level
Correct Answer: A ✓
Rationale: A multimeter measures voltage, current, and resistance.
13.Mold growth is primarily caused by
A. Dry air
B. Excess moisture
C. Bright light
D. Clean surfaces
Correct Answer: B ✓
Rationale: Moisture accumulation promotes mold development, especially
in poorly ventilated areas.
14.What is the function of a fuse
A. Increase power
B. Store energy
C. Protect circuit from overload
D. Cool wires
