As the opponent in the debate, how to demonstrate is better?

Drill's selective questioning is one of the offensive moves used by many debaters. Usually this kind of question is premeditated, which will make people fall into a "dilemma". No matter which choice the other party makes, it is not good for them. The correct way is to take a preset option from the other party's multiple-choice questions and carry out a strong backchat to fundamentally frustrate the other party's spirit. This skill is to grasp the root cause of the problem.
