+Results can be submitted for the test set (we closed the validation leaderboard, as it was no longer informative). Scores are expressed as the percentage of correct answers for a given split. 
 
 Each question calls for an answer that is either a string (one or a few words), a number, or a comma separated list of strings or floats, unless specified otherwise. There is only one correct answer. 
 Hence, evaluation is done via quasi exact match between a model’s answer and the ground truth (up to some normalization that is tied to the “type” of the ground truth).
