Maybe review over the text it’s talking about. I would help but there is not text for what you are needing help with. Try putting a photo of the text your questions are linked to? Then it would be easier to help with what your asking.
Kylie had 4 chocolate bars and she gave each one of her friends one, they were all happy but there was a problem, Kylie didn’t have one for her.
The introduction I would say because in your introduction you use a grabber which should grab the attention of your readers. But also maybe your first body paragraph... it all just kind of depends on how YOU want to structure your essay.
