a is the right use of 'weather."
Im assuming you have read the book already that its talking about. So what you need to do in the second part is describe how the item affected the character. Like cause and effect. How did the rash effect him? After you do that make sure you say where you got the evidence from. Then the 3rd step explains itself. Write a paragraph on how the items affect their perspective. Hopefully this helps guide you because I dont have the time to read the full book. Just follow those guidelines
I cannot see which is italicized so I will say which one is cause and which one is effect: The effect is that the cookies in the oven became charcoal. The cause of why the cookies became charcoal is that 'David left the cookies in the oven too long.'
