How should the date item be annotated for the Video QA task?

“Hello. I would be most grateful if you could inform me on how to create annotations for the Video QA task. As per the Readme.md in the dataset folder, there are seven types of task annotations ranging from A to G. However, none of these are for the Video QA task. Hence, if there is already a solution to this problem, please notify me. Thank you very much.”
