Bradbury establishes that the people of 2053 are less "alive" than Leonard Mead
by

characterizing his neighbors as "comatose" and "vegetables."

Explanation:

I take English II in high school and got the same question for Ray Bradbury's short story, "The Pedestrian." There are more questions, but we are given multiple choice answers, and the answer above makes more sense than the other answers. I didn't know if it was the answer above or describing the setting Mead walks through as "a graveyard" and "tomblike."...but the first one made more sense, so I picked that one. Hope this helped. :)

i believe that's the correct answer
