Multi-hop question answering (QA) requires reasoning over multiple documents

However, providing supporting evidence is not enough to demonstrate that a
model has performed the desired reasoning to reach the correct answer. Most
existing multi-hop QA methods fail to answer a large fraction of sub-questions,
