Write an “Initial Reaction” of at least 3 sentences

I’m working on a english writing question and need an explanation and answer to help me learn.

Read So What? Chapter 3 “How do we select and use sources responsibly?”
Think about how the chapter applies to your Visual Analysis essay.
Take notes using either of the note-taking styles you read about earlier (Considering Sources or Double Entry).
For Considering Sources approach:
Write an “Initial Reaction” of at least 3 sentences.
Pull at least three direct quotes in the “Quotations to Consider” section
Write 150-200 words in the “Reconsidering the Source” section.
Include page numbers after each direct quote.
Be sure to mention how the reading will help you prepare your first draft of the visual analysis essay.
For Double Entry approach:
Pull at least six direct quotes. Put them in their own box in the left hand column of your chart.
Respond to each quote with at least two sentences.
Include page numbers after each direct quote.
Be sure to mention how the reading will help you prepare your first draft of the visual analysis essay.
