I thought it would be stressful having to participate in a debate for my final exam. But with a partner to help, it was actually a nice change of pace. We argued our case thoroughly, presenting lots of evidence. We even got to use the rebuttal we’d rehearsed. Well, a year’s worth of research really paid off. Which phrase from the passage best supports the conclusion that the student is describing a policy debate?

argued our case thoroughly
presenting lots of evidence
the rebuttal we’d rehearsed
a year’s worth of research
