Forget question 2, forget your grade, forget your argument with your roommate. Then think over every one of the 5 possible answers. Take them all seriously, until you have finished all 5. Don't jump to conclusions. Don't focus on any single answer until you have really considered all answers.
Stupid answers come from rushing.
So slow down and think about all five choices. When you have finished question 1, go on to question 2 and forget everything else including question 1. Read the questions naturally but carefully, just as you would read the textbook, or hear the lectures. The teacher puts a lot of care into wording the questions in the most natural, direct, easily-understood, and clear way. But scientific writing is not like street-corner conversation.
