A. Increase building weight
B. Slow fire spread and maintain structural integrity
C. Improve aesthetics only
D. Reduce construction cost
Answer: B. Slow fire spread and maintain structural integrity
Rationale: Fire-resistant materials are designed to delay fire damage and
preserve structural stability.
2. Which material is commonly used for fire-resistant walls?
A. Gypsum board
B. Cardboard
C. Plastic panels
D. Fabric sheets
Answer: A. Gypsum board

A. Ability to withstand high temperatures for a period of time
B. Color durability
C. Weight reduction
D. Flexibility only
Answer: A. Ability to withstand high temperatures for a period of time
Rationale: Fire resistance is measured by time before structural failure.
4. Which material is naturally fire-resistant?
A. Concrete
B. Paper
C. Wood (untreated)
D. Foam
Answer: A. Concrete
Rationale: Concrete resists fire and does not burn easily.
5. What is the purpose of fire rating in construction materials?
A. Measure fire resistance duration
B. Determine paint color
C. Measure cost efficiency
D. Improve texture
Answer: A. Measure fire resistance duration
,Rationale: Fire ratings define how long materials resist fire.
