What story is this from, i need a ll more info to help
You could use a topic such as "2 common breeds of dogs and their characteristics" or "How to raise a tomato plant from seed" or "Critical tips for surviving in the wilderness", etc. (Basically, you need to do it on a topic you are familiar with and interested in)
The verb is walked because it's an action, quickly describes the action that is an adverb so the correct answer is walked
Repetitious or Drab, Hope this helps!
