Difficulty: MediumElectoral Systems and Their Characteristics

Match each electoral system on the left with its defining feature or operational mechanism on the right.

  • First-Past-The-Post (Simple Plurality)The candidate with the highest number of valid votes wins, regardless of whether an absolute majority is attained.
  • Proportional RepresentationLegislative seats are allocated to political parties based on the percentage of total votes cast nationwide or by district.
  • Second Ballot (Run-off) SystemA second election is conducted between the leading candidates if no contestant secures an absolute majority in the first round.
  • Alternative Vote (Preferential System)Voters rank candidates by preference on a single ballot, and lower-ranked candidate votes are redistributed until a winner reaches an absolute majority.

Answer

First-Past-The-Post pairs with winning by simple plurality without needing an absolute majority; Proportional Representation pairs with allocating legislative seats based on party vote percentage; Second Ballot System pairs with holding a run-off election when no absolute majority is met in the first round; Alternative Vote pairs with voters ranking candidates on a single ballot with preference redistribution.
Each electoral system is correctly matched to its defining characteristic: First-Past-The-Post awards victory to the candidate with the highest votes regardless of absolute majority; Proportional Representation allocates seats according to party vote shares; Second Ballot requires a run-off round if no absolute majority is achieved in round one; and Alternative Voting utilizes preferential ranking on a single ballot.

Step-by-Step Solution

1
Analyze First-Past-The-Post (Simple Plurality)
Identified that FPTP determines victory by simple plurality, where obtaining the highest number of valid votes is sufficient regardless of reaching 50% + 1.
Differentiates simple plurality from majority requirements.
2
Analyze Proportional Representation
Identified that PR awards legislative seats according to the proportional vote percentage received by political parties.
Distinguishes party-list and quota-based seat allocation from single-member winner-take-all systems.
3
Analyze Second Ballot (Run-off) System
Identified that the Second Ballot system requires a second election round between top candidates if no candidate attains an absolute majority in round one.
Highlights the two-stage process necessary to ensure a majority outcome.
4
Analyze Alternative Vote (Preferential System)
Identified that Alternative Voting allows voters to rank candidates in order of preference, redistributing lowest-ranked votes until a winner achieves an absolute majority.
Matches preferential single-ballot voting mechanics.
