Question

Sweaters made of acrylic keep us as warm as woolen sweaters.

• A. Acrylic
• B. Rayon

Answer 1

The correct option is B

Rayon

Many of the sweaters, shawls are actually not made from natural wool, though they resemble wool. These are prepared from a synthetic fibre called acrylic. The wool obtained from natural sources is quite expensive, whereas clothes made from acrylic are comparatively cheap. However, acrylic sweaters are not as good insulators as sweaters made of wool and hence are unsuitable for very cold temperatures.
