Definition: 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.
Input: Prompt: These bitches get around. Even the ones you swore didn't, 
Completion A: and you're not really a good listener. So they need me to play a little back and forth with you and tell you what to sound like. 
Completion B: there are always a few more. So get your ass in gear, start climbing, and let them do the rest."  Bethany'

Completion B
