Answer 1

Smooth muscles are primarily responsible for involuntary movements within internal organs. Among the options provided, the activity that involves smooth muscles is:

**digesting food**

Smooth muscles are found in the walls of the digestive tract and help move food through peristalsis. While smooth muscles are not responsible for playing the piano, pumping blood (which involves cardiac muscle), or walking (which involves skeletal muscle), they do play a critical role in the digestive process.
