if she spoke very loudly then she would make people think she is mad
and if she spoke a high pitch and tone she would hurt someones ear like her teacher and if she does that the teacher can't hear and she can't be graded
and if she speeds up when she is nervous no one will understand what she is saying
so that gives us c. if she pauses between sentences then the audience can hear and understand what she is saying so c. hope this helps with your question
