What is the main idea of this excerpt? mad cow disease ended because of government bans on feeding cows certain foods, but people were angry that governments did not act sooner. mad cow disease was originally caused when governments allowed for cows food sources to be contaminated, so people were angry at their leaders. both farmers and customers had been aware of mad cow disease, but they did not think their governments should have done anything to stop it

I think it would be or similar to "Though the government did help end mad cow disease, the people were angry they didn't help sooner."

A. Mad cow disease ended because of government bans on feeding cows certain foods, but people were angry that governments did not act sooner.

Explanation:

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.
