Activity 13 writing what you see: describing actions

I can't help that much, but what they want you to do is go to a park or some place with people and describe what they are doing for example they may be:
Riding a Bike or Playing Frisbee
Basically you need to write what you see outside using the things they want you to use 

Abiography is a description of a real person's life, including factual details as well as stories from the person's life. biographies usually include information about the subject's personality and motivations, and other kinds of intimate details excluded in a general overview or profile of a person's life.
