Polymers J and K are made from crude oil. In the past, firefighter uniforms were made from wool. Wool is obtained from sheep.
Why are many fabrics made from polymers instead of wool?

Answer options:

Polymers are man-made

Polymers are more hard-wearing

Wool is more easily available

Wool is more flame resistant

How to approach this question

Compare the properties of synthetic polymers with a natural fibre like wool. Consider factors like durability, availability, and cost, which are important for mass production of fabrics.

Full Answer

B.Polymers are more hard-wearing✓ Correct

Polymers are more hard-wearing

Many modern fabrics are made from synthetic polymers instead of natural fibres like wool for several reasons. One of the main advantages is durability. Polymers can be designed to have specific properties, such as high tensile strength and resistance to abrasion, making them very hard-wearing and long-lasting compared to many natural fibres. They are also often cheaper to produce in large quantities.

Common mistakes

✗ Choosing "Polymers are man-made" - this is a description, not a reason for preference. ✗ Choosing an incorrect statement, such as "Wool is more easily available".
