A. Dry cutting with high speed
B. Wet cutting to reduce dust and heat
C. Polishing tile surfaces
D. Drilling holes in stone
Answer: B
Explanation: A wet saw uses water to cool the blade, reducing dust and improving cutting
precision.
Question 12: In a technical drawing, what do the numbers inside a tile pattern typically
indicate?
A. Color codes
B. Tile sizes or dimensions
C. Installation sequence
D. Grout spacing
Answer: B
Explanation: Numbers usually refer to tile sizes or dimensions, which help determine layout and
spacing.
Question 13: Which of the following materials is known for its natural variation and
unique patterns?
A. Ceramic
B. Porcelain
C. Natural stone
D. Vinyl
Answer: C
Explanation: Natural stone, such as granite or marble, features inherent variations that create a
unique look.
Question 14: What is the purpose of expansion joints in tile installations?
A. To increase tile adhesion
B. To allow for thermal expansion and contraction
C. To provide extra support
D. To simplify the installation process
Answer: B
Explanation: Expansion joints accommodate movement caused by temperature changes,
preventing cracks.
