Read this excerpt from "The Tell-Tale Heart" by Edgar Allan Poe. Above all was the sense of hearing acute. I heard all things in the heaven and in the earth.

How does the situational irony of this excerpt affect "The Tell-Tale Heart"?

The narrator brags of his sharpened senses, but his "acute hearing" is ultimately his downfall.

It explains why the narrator is so quiet around the old man as he lay sleeping.

The narrator thinks his hearing is very good, so it is surprising when he fails to hear the old man groan in his sleep.

The narrator's hatred of the old man is shown to be entirely rational and justified.

you need to post the passage so we know what you’re talking about

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.
