The document discusses prepositional phrases and the use of commas with them. Prepositional phrases answer questions of when or where and are separated from the main idea with a comma if they come at the beginning of a sentence. Examples are provided of sentences with prepositional phrases that use commas correctly, including ones about passengers on a train, rooms below deck, clues in chapters, and voices in someone's head. It also explains that a comma is needed in the sentence "When Sarah Winchester passed, the house had 160 rooms" to avoid changing the meaning.

2. Identifying Prepositional phrases
• Prepositional phrases tell when or where. Commas will follow the
prepositional phrase to separate the ideas as one being introductory
and the other being the main idea.

4. All the passengers aboard the runaway train were
frightened.
• This prepositional phrase answers the question of where.
• The passengers are on the runway train.

5. All rooms below deck are for sleeping.
• This prepositional phrase answers the question of where.
• This tells where the rooms are located.

6. The clues within the first few chapters will lead to
the murderer.
• This prepositional phrase answers the question of when.
• This tells where the clues where given

7. I will not obey the voices in my head.
• This prepositional phrase answers the question of where.
• This informs us that the voices exist in my head.

8. “When Sarah Winchester passed, the house had
160 rooms.”
• “when Sarah Winchester passed,” is the prepositional phrase because
it answers the question of when. It is when she passed or died.
• “the house had 160 rooms.” Is the main idea because Sarah's house
had 160 rooms after she passed.

9. When Sarah Winchester passed the house
had 160 room.
• This would be wrong because without the comma the sentence
changes to talking about Sarah passing a house.
