Thanks for your submission.

1. Can you include a README that clearly outlines the problem statement, the deployment steps, the sample questions and limitations
2. Can we avoid distributing pdfs in the repo, especially since their license is not specified, you can include a script in the prereqs to download the relevant data
3. Can you separate the lambda function from the notebook , use only a single notebook, and include test questions in the notebook. Ideally, we want to be able to deploy the agent via cloud formation (see other examples in the catlog)
