Correct option is C
The correct answer is A and C.
· A pashmina shawl is very thin yet very warm.
· The goats from which the soft pashmina wool is collected, are found on very high altitudes of 5000 metres.
· In winter, the temperature here drops below 0° C (–40°C).
· A coat of warm hair grows on the goat’s body which protects it from extreme cold.
· The goats shed some of their hair(fur) in summer.
· This hair is so fine that six of these would be as thick as one hair.
· The fine hair cannot be woven on machines and so weavers of Kashmir make these shawls by hand.
· This is a long and difficult process.
· After almost 250 hours of weaving, one plain pashmina shawl is made.
· The Changpa tribe, of Ladakh, is known for making pashmina shawls.
· It is believed that a pashmina shawl is as warm as six sweaters.
