Which feature is listed as a characteristic of nylon rope but not specifically attributed to polyester in the material?

• A. More stretch
• B. Higher melting point
• C. Excellent strength
• D. Lightweight

Answer: (A)

Nylon rope is typically described as having more stretch under load because its polymer chains can extend more before reaching their limit. This greater elasticity lets nylon absorb shock and elongate as a rope under tension, a trait that is highlighted for nylon but not specifically attributed to polyester. Polyester, while strong and light, is comparatively stiffer and stretches less, so it doesn’t share the same level of elongation. The other traits listed—melting point, strength, and lightweight nature—are not unique to nylon and can be true for both materials, so they don’t single out nylon in the same way.
