| Challenge: | Existing methods for evaluating plausibility of events are focused on measuring causal dependency between events or actions. |
| Approach: | They propose a task to identify the more plausible alternative with their commonsense causal context. |
| Outcome: | The proposed task is based on a visual COPA dataset with 380 questions and over 1K images with various topics. |

| Challenge: | Existing models are brittle for adversarial perturbed questions, causing uncertainty . a dataset with annotations on unanswerable questions is not available to solve this problem . |
| Approach: | They use crowdsourced annotations to annotate unanswerable questions . they also annotated which part of the question causes unanswered questions a . |
| Outcome: | The proposed dataset can be used to improve model interpretation, authors say . they find that existing models are brittle for adversarial perturbed questions . |
