Review the item:
Maria knowed the futility of her task that
October afternoon. As she swept
off the front sidewalk, more leaves
fell from the trees overhead,
sprinkling the concrete with color.
The first verb, knowed, is the problem. The sentence requires the simple past. Knew is the correctly spelled form.

Fell, the verb you chose, is perfectly correct. Before you continue, review the rules for irregular verbs.
