Please help me understand what the question is asking below. "How are the characters, setting, and problems like those in other stories you have read?" Thank you.

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.

in ray bradbury's short story "a sound of thunder", mr. eckels's fearfulness leads to drastic consequences for the rest of the world.

in the story, mr. eckels, who is a hunter, hires a time travel company to travel to the age of dinosaurs. although he is excited for the hunting expedition at the beginning, when they reach there and mr. eckels sees the tyrannosaurus, he feels frightened. as he is afraid of the tyrannosaurus, he steps off the path although he has been warned not to do it. by stepping off the path, the entire course of the future is affected: mr. eckart alters the future by stepping on a butterfly, which causes a new man to be elected president in the future. in that way, it is mr. eckart's fearfulness what triggers 'the butterfly effect' and what leads to drastic consequences for the rest of the world.
