Question

___ is a strong and elastic fibre that is used to make ropes for rock climbing.

Answer 1

Nylon fibre has properties like high strength, elasticity and lightweight. We use many products made from nylon. For example, socks, ropes, tents, toothbrushes, car seat belt, sleeping bags, curtains, etc. Nylon is so strong that it is also used for making parachutes and ropes for rock climbing. A nylon thread is actually stronger than steel wire.
