making it essential for accurate millwork installation.
3. What is the primary purpose of acclimating wood before installation?
A. Increasing its weight for stability
B. Allowing it to adjust to ambient moisture and temperature
conditions
C. Strengthening its structural load capacity
D. Changing its natural color permanently
B
Acclimation allows wood to stabilize to site conditions, reducing risks
of warping, shrinking, or expanding after installation.
4. Which fastener is most appropriate for securing heavy cabinetry to
wall studs?
A. Drywall screws
B. Finish nails
C. Structural lag screws
D. Roofing nails

, 9. What does “scribing” in millwork installation refer to?
A. Painting finished wood surfaces
B. Cutting material to match irregular wall or floor surfaces
C. Assembling hardware components
D. Sanding edges to a smooth finish
B
Scribing is the process of transferring wall irregularities onto

10. Which material is commonly used for cabinet box construction
due to its stability and cost-effectiveness?
A. MDF (Medium-Density Fiberboard)
B. Solid oak only
C. Cast iron
D. Tempered glass
A
MDF is widely used for cabinet carcasses because it is stable, smooth,
and cost-effective compared to solid hardwood.

installation?
A. Locating electrical outlets
B. Detecting wall studs behind finished surfaces
C. Measuring humidity levels
D. Cutting drywall panels
B
A stud finder helps locate structural framing members for secure
