The question is asking how the perspective in which the story is told is used by the author to portray certain aspects. This could mean first person vs third person, it could be protagonist vs antagonist...
If it's in first person, is it likely to give insight on the characters inner thoughts and bring a closer connection to them. It could be to give a bias portrayal of the story that you are meant to see through or sympathize with. Other than that, I don't know. I haven't read "The Rescue Mission"
When writing your paragraph, it's hard to know where to start. I don't know what you've been taught, but this is what I find works the best.
The opening sentence should include the title, author's name, and the main point of your answer:
<u>In Mary Sue's novel, <em>The Green Tablecloth</em>, the protagonist overcomes their fear of loud noises by allowing themself to seek professional mental help. </u>
It shouldn't go into too much detail, but you should know what you're reading about right away. Hope that helps.
