I find some annotation seem incorrect. for example:

1. for video "RCAqKnvu_P0"
   question: How much does the vlogger pay to the hotel for 8 days?A. $ 168 B. $ 167 C. $ 15 D. $ 416.
   gt:D .
   but，I find the correct answer should be $ 169.
2. for video "HfEVEGf1A8Q"
   question: When is the school let out in the afternoon?A. 2:00 pm B. 3:30 pm C. 2:30 pm D. 3:00 pm.
   gt: A .
   but，I can not get the information from the video.

Can you explan the above problem and can you tell me how to generate the annotation. thx!
