Midterm #1 correction

A chance to correct your midterm. 

For multiple choice you missed:  in your own words, explain the correct answer

For essay question (required if grade is 16 or below), write a new answer. Remember the standard is that you should be able to hand the essay to someone not in the class and they would understand after reading your essay. 

(If you have no corrections to do, please just submit an assignment that says that).
