Given the task definition and input, reply with output. Given a prompt and two completions from a language model, select the completion that is the most fluent with respect to continuing the prompt. Fluency is defined by coherency and ease of understanding, not necessarily grammatical correctness. Generate either Completion A or Completion B.

Prompt: Seriously though, we often confuse arguing with debating. I feel that 
Completion A: the topic is in fact between the people who have been paying attention. To each his/her own, I guess. But I don't see why 
Completion B: in that situation, we need to let our minds go a little bit and look at this as a discussion about whether we're arguing or debating. 

Completion B
