What is the thickness of scratch lines in javelin throwing__________?
Show answer Hide answer
Answer: D. 7cm
Explanation
Scratch lines and arc boundaries in javelin throwing have a mandated thickness of seven centimeters. This wide painted line marks the foul boundary that athletes must not touch or cross during their throwing motion. Field officials use these clear white lines to instantly determine whether a throwing attempt is legal or a foul. The javelin throwing arc is formed by a painted strip curving outward from the edges of the runway approach. Athletes must release the implement before any part of their body touches or crosses beyond the scratch line. Precise field markings are essential for maintaining accurate officiating standards in all throwing disciplines.
Option A suggests four centimeters, which is too thin to meet the official thickness requirement for scratch lines. Option B proposes five centimeters, representing a line width commonly used for standard lanes rather than throwing arcs. Option C lists six centimeters, an intermediate measurement that falls short of the mandatory seven-centimeter width.
