1. Which material is commonly used for high-quality architectural cabinet face
frames because of its stability and appearance?
A. Particleboard
B. Hardwood lumber
C. Gypsum board
D. Concrete
Answer: Hardwood lumber
Rationale: Hardwood lumber is commonly selected for exposed face frames
because it provides strength, durability, and an attractive finished appearance.
2. What is the primary purpose of a shop drawing for architectural
woodwork?
A. To replace the construction contract
B. To show detailed fabrication and installation information
C. To determine the contractor's insurance premium
D. To calculate payroll taxes
Answer: To show detailed fabrication and installation information
,Rationale: Shop drawings communicate dimensions, materials, construction
details, hardware, finishes, and installation requirements before fabrication.
3. Which sheet material is manufactured by bonding wood fibers with resin
under heat and pressure?
A. MDF
B. Solid-sawn lumber
C. Plywood veneer
D. Laminated glass
Answer: MDF
Rationale: Medium-density fiberboard is manufactured from refined wood fibers
combined with resin and compressed under heat and pressure.
4. What is the primary advantage of plywood over solid wood for many
cabinet components?
A. It always costs less
B. It has greater dimensional stability
C. It requires no finishing
D. It cannot absorb moisture
Answer: It has greater dimensional stability
Rationale: Cross-laminated veneers in plywood reduce movement compared
with many solid-wood components.
5. What does the term "veneer" generally refer to in architectural woodwork?
A. A thin layer of wood
B. A metal reinforcement
C. A plastic fastener
D. A concrete coating
Answer: A thin layer of wood

8. What is a major concern when installing solid wood panels in a controlled
interior environment?
A. Electrical conductivity
B. Seasonal dimensional movement
C. Concrete curing
D. Glass tempering
Answer: Seasonal dimensional movement
Rationale: Solid wood expands and contracts with changes in moisture content,
so fabrication and installation must allow for movement.
9. What does "kerf" refer to in woodworking?
A. The width of material removed by a saw blade
, B. The thickness of a veneer
C. The length of a cabinet
D. The depth of a screw head
Answer: The width of material removed by a saw blade
Rationale: Kerf is the width of the cut produced by a saw blade and must be
considered when calculating cut dimensions.
10.Which tool is commonly used to make precise straight cuts in sheet goods?
A. Table saw
B. Pipe wrench
