Assess students' ability to apply electoral-system calculations and analysis by predicting how national party seat distributions would change if a hypothetical country moved from first-past-the-post (single-member districts) to a specified proportional representation method. Provide vote shares (national and/or district-level), require seat allocation using a named formula (e.g., D'Hondt or Sainte-Laguë), comparison of outcomes, and a brief explanation of effects on small parties, coalition likelihood, and overall representation.
