Although the question is incomplete because it does not provide any specific reference or context to what debate it refers to, we can say that in any debate when someone challenged another speaker's reasoning, evidence, ideas, or conclusion, this person has to answer and provide the support for its arguments to clarify any mistakes or attacks of the rival and pose another questions or accusations against its rival.
