Provides Inline Citations, Allowing Subsequent Chains To Trace Sources

For each "document" and "source" pair, review the content to determine if it provides sufficient information to answer the given "question". If it does, insert a sentence into the main body of the text that refers to the "document", followed by its numerical citation in square brackets. Provide a legend at the end with the sources.

example:
Question: What are the key contributions and areas of research in the field of language models and natural language processing?

According to MIT researchers, language models play a vital role in natural language processing tasks [1]. Deep learning techniques have been extensively explored for large language models as documented by Smith et al. [2]. Reinforcement learning approaches have also been investigated for training intelligent agents [3]. The GPT architecture and training methods have been studied in detail by Johnson et al. [4]. Various studies have emphasized the importance of efficient training strategies for large language models [5].
