Properties and Applications

Question 13mcq

B.Smell the fleece closely to test quality.

C.Eat food while sorting fleece.

D.Avoid cleaning the workplace.

Question 14mcq

Which statement shows a balanced ethical understanding of silk production?

A.Silk has no connection with living organisms.

B.Traditional silk gives useful fibre, but it may raise concern because living pupae can be killed.

A.The silk scarf, because silk is always the warmest fibre.

B.The wool muffler, because wool comes from cocoons.

C.Both are equally warm because all fibres trap the same amount of air.
