 We share both a version where each question was verified by a human, and a larger, solely automatically generated version ("unverified"). We recommend to primarily use the human-verified version, which is also the default option when loading the dataset.
 
+Each sample in the dataset contains the following fields:
+
+- **question**: Our new multi-hop question with added reasoning (case 1 above)
+- **answer**: The answer to the last hop (case 1, 3 and 4 above)
+- **context**: Relevant context information to answer the previous question (relevant for all cases except case 4)
+- **previous_question**: The previous 2-hop question from the original dataset (case 2 above)
+- **previous_answer**: The answer to the previous 2-hop question (case 2 and 5 above)
+- **question_decomposition**: Each question of the reasoning chain. List of entries with keys "sub_id" (position in the chain), "question", "answer", "paragraph_support_title" (relevant context paragraph). (sub_id 1 → case 6; sub_id 2 → case 5; sub_id 3 → case 4)
+- **question_on_last_hop**: Question for case 3 above
+- **answer_type**: Type of the expected answer
+- **previous_answer_type**: Type of the answer to the previous 2-hop question
+- **no_of_hops**: Number of extra hops to answer the additional reasoning question (might be more than one for more complicated tasks)
+- **reasoning_type**: Might contain "Symbolic", "Arithmetic", "Commonsense"; depending on which kind of reasoning is required for the additional reasoning
