RLHF Training Process with PPO

An AI development team is considering two different methods for training a conversational assistant to be more helpful and aligned with user expectations. Method 1 involves having human experts write a large dataset of ideal, high-quality responses to various prompts, and then training the AI to imitate these examples. Method 2 involves having the AI generate several responses to each prompt, and then asking human experts to simply rank these responses from best to worst. This ranking data is then used to train a separate 'preference model' that provides a reward signal to guide the AI's learning process. Which statement best analyzes the primary advantage of Method 2 over Method 1?
