Priority disputes can hinge on dates, lab notes, patents, and publicity—sometimes all at once. This quiz focuses on who claimed what, why it was contested, and how history (and law) judged the outcome.

Difficulty is balanced as Mixed: straightforward recognition questions are blended with deeper, context-heavy items so the challenge stays varied. Before you start, choose your question count and select a difficulty level to tailor the run—short practice sessions or full-length deep dives both work well.
