It's either Character vs society or character vs nature. It could be either, honestly. Character vs nature because she was burnt by a fire, but it could be vs. society because most of the story focuses on what other people view her as. I believe the answer that they're looking for, however, is character vs society.
The tone is the way the author expresses his attitude through their writing.
The tone can change, or stay the same way throughout the literary work.
Tone is expressed by your point of view, your diction, etc.
Hope this helped!
Allusion is the comparison to something significant, so that the reader is able to relate.
