I’m stuck on a English question and need an explanation.

Step 1: View the Following Videos
Step 2: Respond by Wednesday:

What should we do as we peer review other’s writing? Why is it important to peer review and then revise as we write? 
How will you use this information to review your partner’s paper this week? What new things did you learn and are excited to try? 
What will parts of the review will challenge you the most? Do you have any further concerns about the process? 

Step 3: Read and Respond to Your Peers by Friday
Once you have written your responses, you are to respond to two of your peers’ posts in at least 100 words each. Reply to two posts that have yet to be responded to by a classmate. If everyone’s post has been responded to, evaluate the ones with the least amount of replies. For example, if every student has at least one reply, then respond to the students who only have one or two replies instead of those who have 5 or 6 already.
Use your personal experience, if it’s relevant, to support or debate other students’ posts. If differences of opinion occur, debate the issues professionally and provide examples to support opinions.
