Midterm #2 Corrections

A chance to correct your midterm, plus correcting the grading of problem #2. 

For multiple choice you missed:  in your own words, explain the correct answer. If you answered A, D or E on problem #2, see special instructions below.

For essay question (required if grade is 14 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. 

Problem 2 special instructions: As a number of you suspected, there was a mistake on the exam (I swapped introvert and extrovert on options B & C; the intended answer was E). If you answered A or D I'll accept those as correct answers. Please attach a photo of problem 2 from your exam and your current grade, and we will adjust your grade on the midterm accordingly.
