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 60 second rounds, although not bonus questions per se, retain some of the elements of binary matching bonuses.
