Question

Which detail from "Undercover Farmer” best shows that the narrator’s activism on behalf of farm animals changed practices in the community?

I decided to show what I’d discovered to my friends so they could help me figure out some next steps.
Three weeks later, two businesses had signed on, and two more said they’d think about it.
I was assigned to feed the pigs, which was lucky because one of the things I’d read about was mistreatment of sows while they are pregnant.
I got another friend to make posters and put them up on the bulletin boards at school.

Answer 1

"Three weeks later, two businesses had signed on, and two more said they’d think about it."

This shows concrete community change—businesses adopting the narrator’s suggested practices.
