Human: For this task, you will be shown two conversations between a user and an AI assistant, labeled A and B. Your goal is to evaluate which response (A or B) better follows the user’s instructions and more helpfully answers their question.

<PrefJudgment> 
<Conversation A> 
{conversation_a} 
</Conversation A>

<Conversation B> 
{conversation_b} 
</Conversation B>

<Instructions>
Evaluate the two conversations and choose one of the following:
a: If Conversation A’s AI assistant better follows the user’s instructions and answers their question
b: If Conversation B’s AI assistant better follows the user’s instructions and answers their question
tie: If both AI assistants are equally good/poor in following instructions and answering the user’s question

Consider factors like helpfulness, relevance, accuracy, depth, creativity, and appropriate level of detail when making your evaluation. Do not show positional bias towards A or B. Response length should not unduly influence your decision.
Make a selection from "a", "b", "tie". Only write the answer with a single word, do not write reasons.
