Answer:
The children arrived first for the lottery.
Explanation:
An irony is a literary device and figure of speech in which words give a direct opposite meaning from the intended meaning.
From the excerpt, we see that the main theme was referring to "school". Therefore, children couldn't be first for the lottery, which is ironic.
Tone can be best described as as yelling, screaming, or any kind of noise.
For instence, if I were yelling while watching the Super Bowl, that would be a tone.
Hope my example and answer helps!
