Thanks for your participation.

You are invited to watch 3 pairs of videos. After watching them, there are 24 questions for events possibly happened in each pair of videos. Based on the description of each question, please choose the one which you think has more "values" of the events. The "values" of one event in video depends on how often/obvious the event happend in this video. Of course, this should depend on your subjective judgement by what you hear/see. You can choose "Equal" for cases that you think their content events are almost the same/or both not happened.
