Answer:
a) Apart from sheep, wool also comes from the angora goat, yak, llama, alpaca, and even camels. All these animals have a thick coat of hair or fleece, which keeps them warm. Wool is obtained from this fleece. Shearing is the first step in processing fibre into wool.
b) Cashmere wool, angora wool, mohair wool and camel wool are some common variety of wool
c) Sorting is any process of arranging items systematically, and has two common, yet distinct meanings: ordering: arranging items in a sequence ordered by some criterion; categorizing: grouping items with similar properties.
d) the production of silk and the rearing of silkworms for this purpose.
