The questions will either be “G” general or “S” specific. Label them as such. General questions will ask you about the passage as a whole and don’t require you to refer to any particular part of the passage – they may ask for tone, theme or main idea. Specific questions ask you to reference a particular word, phrase, or line in the text. After you've read the text, you'll answer the specific questions first and the general questions last. Don't start answering yet, though! You have another step to complete before you get there.
I labeled this first one with a "G" because it's asking for the author's primary purpose, which isn't directly stated in the text.
