some answers not correct, any ways to check it out?

[MarStarck]

this one for example, is "rag" in video
"video": "video_7982.mp4", "question": "What is the order of the letters at the end?", "candidates": [ "gra", "arg", "rag" ], "answer": "gra"

Since the question is about the letter order, the answer is randomly generated. By the way, the answer is directly copied from Perception Test.
