Hi KC,
This is a good source that explains the difference between metaphors and similes:

Hi Einstein,
I give my students this formula when they are unsure of how to answer the prompt. It isn't the "right" answer; but is just a simple way of getting started.
1st sentence - answer prompt directly
2nd sentence - validate the answer by giving it some context/explanation
3rd sentence - acknowledge the counterargument
4th to 5th sentence - signpost the main arguments in your body paragraphs
E.g. The rescue of Sohrab was a cathartic event in Amir’s life, one that allows him to forgive himself and atone for his and his father’s actions. Amir is haunted by a constant feeling of guilt that he needed to find the courage to resolve. Although it is arguable whether Amir truly ever forgives himself, it cannot be denied that Sohrab cleanses a great proportion, or perhaps all, of Amir’s guilt. It is his courage, the support of those around him, and interestingly his guilt that compel him to change.
