Answer:
I do not have the text you are referring to but I can explain what the tone is so that you can identify it by yourself.
Explanation:
When we talk about tone, we are referring to the way in which a writer addresses a topic or addresses his readers.
The way to express it will be through his own opinion, choosing certain types of phrases or words to convey this opinion.
In short, every text will present a theme, but the tone is the way in which that theme is presented through the words the author chooses to do it.
