Mr Brunner hurt percy by telling him he is not normal and he thought he was being rude so he was hurt and walked away when he was only trying to say that he was not a normal human/he was a half-blood
You would use "he" here because at a later part we encounter "he can graduate" which shows that the doer of the action is a male and therefore requires "he" to be used.
In a bar graph you can put in the Y axis the percentage from 0 to 100 and you just put the states in the X axis, this way you can make a visual representation of the differences on the populations ages in the different states of the United States.
