Find a partner. Then choose a controversial issue that has two distinct and opposed sides. Before you begin, have your partner decide her position on the issue. Then you take the opposite stance. She then makes her case, but you can reply only with questions—not with statements, counterarguments, or insults. These questions must also abide by three rules: (1) You cannot ask yes-no questions. (2) Your questions cannot be veiled opinions. (3) Your partner must answer each question.
