6. Fourth, the invitations should be sent.
The structure of the paragraph is organized as a numbered list that the host must do in order to have a great party. Each sentence that is part of the list begins with an ordinal number (first, second, third). It would make sense to have the next sentence begin with the word fourth. Also, the only thing left out to planning the party is inviting the guests.
12. C. I thought about what he'd said soon I realized he was right.
There are two independent clauses in this sentence: "I though about what he'd said" and "soon I realized he was right." These two indpendent clauses must be separated with a period or joined together with a semicolon or a comma and a conjunction.
14. Prewriting
John is doing some brainstorming of his topic ideas. Brainstorming is in the prewriting stage because he is still trying to figure out exactly what he wants his topic to be. The planning step would involve creating an outline.
15. The game will be called if the storm continues, the weather is dangerous.
This sentence is a runon because it has two independent clauses "The game will be called" and "the weather is dangerous". There is a dependent clause as well: "if the storm continues". The two independent clauses are only separated with a comma. This is not enough. There should be a conjunction as well as a comma or a semicolon.
