the characters are just the people in the story. The setting is where it happens, so if it mainly happens in a school, that would be the setting. The problems could be like two of the characters hating each other or someone's mom sick in the hospital, stuff like that. problems like these usually get solved at the end of the story but they might not, like a cliffhanger.
Then "How are they like other stories you've read?" You can just take any other stories you know and look for things that are the same in both of them. Like if there's a character who's really shy in the story you read for class and the story you read on your own, then you would say " In this story, a character named Mia is really shy. In a story I read on my own, Social Caterpillar, Nicky is really shy and quiet."(Just a fake example) You would do the same thing for the setting and problems.
It is called Alliteration. Alliteration is a literary device where words which are adjacent to each other share the same consonant sound at the beginning. "<span>Peter Piper Picked a Peck of Pickled Peppers" is an example of an alliteration. This literary device is often seen in poems. It is very evident in the literary piece "Beowulf"</span>
Traditionally, the first letter of each line of a poem is capitalized, even if it isn’t the beginning of a sentence. Now the authors are making their poems more alive so you don't have to use capital letters at the beginning of each line of a poem
