A technique exists where multiple language models are used together to improve the quality of a final response. Arrange the following steps to correctly represent the workflow of this technique.

Consider a system where a single user prompt is sent to three different language models simultaneously. Each model generates its own response. These three responses are then passed to a final mechanism that selects the best one or synthesizes them into a new, single response. Based on this workflow, what is the primary advantage of this approach?

A system is designed to improve response quality by using several language models at once. Match each component of this system's workflow to its correct description.
