Request for Baseline Model Code and Guidance on Model Selection and Table Creation

## Description
I am currently working on a multihop QA on TimelineQA. This repository includes dataset generation code, but unfortunately lacks a multihop QA baseline model code. I am in need of assistance in creating a multihop baseline model code and would appreciate guidance on which model to use and how to construct the required tables.

## Requested Actions

1. Multihop QA Baseline Code: Could the repository be updated to include a multihop QA baseline model code?
2. Model Selection Guidance: I need advice on which model would be suitable for creating the multihop baseline code.
3. Table Creation Guidance: I am uncertain about how to construct the necessary tables; any guidance or examples would be greatly appreciated. (Especially for Oracle Retriever)
