The empress found white worms eating up mulberry leaves. She also noticed that they were spinning shiny cocoons around them. Accidentally a cocoon dropped into her cup of tea and a tangle of delicate threads separated from the cocoon.

The route they traveled is still called the 'silk route'. What is the purpose of including the above in a science textbook? a. to develop a historical perspective. b. to develop an appreciation of how incidents/ideas give rise to the discovery of new things. c. to develop a holistic understanding of science d. to make science textbooks light as the above is just for information and not for testing
