Which statement about synthetic rope drawbacks is TRUE?

• A. Can be damaged by ultraviolet light
• B. Is completely unaffected by heat
• C. Is immune to acids and alkalis
• D. Cannot be abraded or worn

Answer: (A)

Ultraviolet light can damage synthetic rope because UV radiation breaks down the polymer fibers, leading to embrittlement, micro-cracks, and a gradual drop in tensile strength with exposure over time. This weakens the rope even if no obvious damage is visible, which is why UV exposure is a real drawback and why that statement is true. By contrast, heat can also harm synthetics—some fibers soften, melt, or lose strength with high temperatures—so they are not immune to heat. They are not immune to acids and alkalis either, as harsh chemicals can degrade the fibers, and they can be abraded or worn through normal use.
