Read the excerpt from "Our Hero."

Wildflower Park has never looked so fine.
You’d never know it was a vacant lot
once, filled with trash and junk and broken glass.
Joe Wilson gathered all of us one day
and gave us gloves and bags from his own store.
We cleaned and planted, built a set of swings,
And now the grass is green and flowers grow
around the playground where the children play.
It is a fitting place to celebrate
the life of brave Bill Wilson on this day.

What is the best inference a reader can make from this excerpt?

Only bravery should be celebrated.
There is more than one kind of hero.
Joe's job was to clean up the park.
Bill specified how to improve the park.
