| Challenge: | Existing methods of automated inference do not provide enough gold explanations to train models . standardized science exams are a challenge task for question answering . |
| Approach: | They propose to manually construct a corpus of explanations for standardized science exams . they also provide an explanation-centered tablestore that contains the knowledge to construct these explanations . |
| Outcome: | The proposed model provides detailed explanations for standardized science exams . the authors show that the proposed model can be trained on the basis of gold explanations . |

| Challenge: | Standardized science questions require combining an average of 6 facts and as many as 16 facts to answer and explain. |
| Approach: | They propose to combine an average of 6 facts and as many as 16 facts to produce an answer for complex questions. |
| Outcome: | The proposed model is based on a corpus of 5,114 standardized science exam questions . it uses multi-fact explanations that combine science knowledge and world knowledge . |
