Answer 1

The correct option is d) Image (iv).

Explanation:

• This question is regarding the Sparrows – here today, gone tomorrow?

• The sheath is a kind of protective cover in which a blade attached to any knife is placed in.

• Similarly, the eggshell acts like a sheath for sparrows. It protects them from the harsh environment and nurtures them until they are hatched.

• Pesticides infect this fatty tissue hence the egg dies.
