As soon as the quiz was announced, Lilith got visibly nervous and started biting her thumbnail. She's not very good at remembering dates and gets everything mixed up, especially when under pressure. She'd have wanted to look like she knew was she was talking about in front of Professor Carrow, so she'd have rambled on a bit, spurting out various famous figures' names until it was obvious she hadn't a clue and was skipped over. After that, she'd have sulked for the rest of the class.
