Because she don't know or she don't want to dance
Julia is described as "haughty" because she is being arrogant and disdainful; her words make her sound as though she thinks herself to be superior in knowledge.
I think it is called a paradox. A paradox is when something seems to contradict itself, but is actually a correct statement. Think of the song "Paradox" from Pirates of Penzance, it is all about an incident that seems to be false yet is true!
The statement that best describes how the pacing of the events heightens tension is: the slow description of the search and surroundings builds anxiety in the reader.
As a reader, you feel anxious as the girl seeks her lover in the surroundings. Everything seems to be slow and the reminiscence of her suffering and how she had escaped from it creates a feeling of rush in the reader.
