a. True

b. False

It is true that the Chinese knew the ways to produce silk during 2700 BC. They kept it secret for a long time because it was a tough process and they could earn profits selling the silk threads to the other regions of the world. Firstly the silk produced was used to make dresses for the people of the royal family in China. Silk is itself a very expensive material as it takes time and labor to produce the fine silk thread.
