scenario_description: |-
  West District's nine ballots, tallied on their own. Scoring round: Avery 35,
  Blake 33, Carmen 32, Elena 25, Diego 0 — Avery and Blake advance. Eight of
  the nine ballots score the two finalists identically (Equal Support), and
  the one decided voter prefers Avery. West's winner: Avery.
  Part 1 of 3 of the consistency exercise (ex01_two_districts.md): East also
  elects Avery, yet the combined city elects Carmen. Ballots adapted from a
  RangeVoting.org example, posed as an exercise in Brendan W. Sullivan,
  "An Introduction to the Math of Voting Methods" (2022), ch. 5.
