Answer:
The word that best describes the tone of this excerpt from Daly's "Sixteen" is hopeful
Step-by-step explanation:
This excerpt from Daly's "Sixteen" has a hopeful tone since it shows how the character keeps a positive thought even when the scenario does not seem to be the same, everything is described in a dark and gloomy form but the last line "But he'd said, "I'll call you." That's what he said—"I'll call you." I couldn't sleep all night." is enlightening the expectations of the characters.
