Answer:
The first excerpt uses facts and statistics, and the second excerpt is told as a story.

I haven't read Fahrenheit 451 in a very long time, but I do remember this part. I think a possible reason as to why the author does this is to start creating conflict and introduce the real turning point of the story, when we find out what the real problem is. Hope this helped.
When revising your work for word choice, it is important to A. use precise and powerful words.
These don't have to be flashy words - but rather convey your idea in the most precise and powerful way. You don't have to use many adjectives in order to do this - or remove any adverbs - but rather choose your words wisely so as to have the appropriate effect on your readers.
