Question

a wooden folding rule is usually marked in ______ on both edges of each side.
a. inches
b. quarter inches
c. eighths of an inch
d. sixteenths of an inch

Explanation:

A wooden folding rule (carpenter's rule) is typically marked with fine graduations for precise measurements in woodworking. Sixteenths of an inch are a common and practical graduation for such tools, as they balance precision and readability for typical woodworking tasks. Inches (A) are too broad, quarter inches (B) and eighths of an inch (C) are less precise than what's standard for a folding rule used in detailed work.

Answer:

D. sixteenths of an inch
