Another excellent submission from avid ZOoF reader Michael!
In his own words:
3. Use a comma to set of a mild exclamation
My answer: Oh no, im not sure how to this!
4. Use a comma to set off an introductory participal phrase
My answer: While trying to order a hotdog, the zebra suddenly realized his true home was in Switzerland
5. Use a comma to set off an introductory adverbial clause
My answer: Somewhere over the rainbow, a unicorn gallops in its freedom.
6. (My fave) Use a comma to set off an introductory phrase.
My answer: When i woke up, I was greeted by the sight of giant Furbys running at me angrly.
