Binary matching bonus

A binary matching bonus is a bonus where each part presents the team with one or more items, and the team must provide a corresponding answer. Binary matching bonuses often have lead-ins of the form "Given the X, name the Y". A characteristic feature of binary matching bonuses is the lack of elaboration or additional information provided in the bonus part: each bonus part is simply a list of one or more items.

Binary matching bonuses are a staple of bad quizbowl, and their prevalence there is probably due to their ease of creation. They are deprecated in good quizbowl: it is much more educational and useful to provide additional information within the bonus part.

NAQT lightning rounds and NHBB 3rd quarter 60-second rounds, although not bonus questions per se, retain some of the elements of binary matching bonuses; however, these are not generally considered bad quizbowl in their context.
