election_title: "Exercise 2 — The tenth ballot: the nine counted ballots"

scenario_description: |-
  The base case: nine club ballots, five candidates. Scoring round: Alex 27,
  Bella 25, Chris 24, Eli 22, Dana 20 — Alex and Bella advance, and Alex wins
  the runoff 6-3. The exercise (ex02_tenth_ballot.md) then perturbs this
  election twice: a forgotten tenth ballot whose FAVORITE is Alex flips the
  win to Chris (a participation failure), and Bella withdrawing flips it to
  Chris too (a runoff-slot spoiler). 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.
