Your sister is an a strict diet, but you are trying to persuade her to try one of your freshly baked cookies.
how will you make them say yes, and listen to you?

You can try several different strategies. If you use logos, you can tell her that it is proven that a single cookie will not severely impact her progress as long as she maintains her diet afterwards. If you use ethos, you can tell her that you are particularly knowledgeable at diets or at baking, and try to convince her that you know best. Finally, if you use pathos, you can tell her how important it would be for you if she tried your cookies, and how happy that would make you.

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.
