Answer :
Let's break down the election process step-by-step to construct the preference table and analyze how the winner was determined, ensuring we understand the violation of the monotonicity criterion. We'll start with the initial vote distribution and follow through with each step.
### Initial Data
- Total Population Size: 1254
- Initial Votes:
- A: 1210
- B: 11
- C: 25
- No elimination (D): 8
### Original Tally
The original tally of votes is as follows:
- A: 1210 votes
- B: 11 votes
- C: 25 votes
- No elimination: 8 votes
Based on this data, let's fill in the initial preference table. We see the first, second, and third choices are allocated accordingly:
#### Preference Table
\begin{tabular}{|c|c|c|c|c|}
\hline
\multicolumn{3}{|l|}{ Straw Vote } & \multicolumn{2}{|c|}{ Second Election } \\
\hline
Number of Votes & 1210 & 11 & [tex]$15 + 10$[/tex] & 8 \\
\hline
First Choice & A & B & C & D \\
\hline
Second Choice & D & A & B & C \\
\hline
Third Choice & B & C & A & A \\
\hline
Straw Vote with B eliminated & \multicolumn{4}{|c|}{Elimination Sequence} \\
\hline
Number of Votes & 1210 & - & [tex]$15 + 10$[/tex] & 8 \\
\hline
First Choice & A & - & C & D \\
\hline
Second Choice & D & - & B & C \\
\hline
Third Choice & B & - & A & A \\
\hline
\end{tabular}
### First Elimination
Since candidate B has the fewest votes (11 votes), B is eliminated. The 11 votes for B go to their respective second choices.
#### Vote Redistribution
The 11 votes are redistributed to candidate C.
#### Tally After First Elimination
- A: 1210 votes
- C: 36 votes (25 + 11)
- D: 8 votes
### Second Elimination
Now, candidate D has the fewest votes (8 votes).
#### Vote Redistribution
The 8 votes are redistributed to their second choices. In this scenario, they would move to their respective second choices in a preferential election.
Since 'D' voters second choice is C, The votes of D are added to C.
#### Tally After Second Elimination
- A: 1210 votes
- C: 44 votes (36 + 8)
### Final Preference Table After Eliminations
This results in a redistribution as follows:
\begin{tabular}{|c|c|c|}
\hline
\multicolumn{2}{|l|}{ Final Vote Redistribution } \\
\hline
Number of Votes & 1210 & 44 \\
\hline
First Choice & A & C \\
\hline
\end{tabular}
Thus, initially A has 1210 votes, B has 11 (shifted to C), C has 25 (and increased after redistribution), and D has 8 (moved to C). Ultimately, candidate A wins by the plurality-with-elimination method with 1210 votes against C's 44. This calculation showcases the step-by-step reductions and transfers during the elimination rounds, acknowledging the appropriate preferences and redistributions.

\end{tabular}
### First Elimination
Since candidate B has the fewest votes (11 votes), B is eliminated. The 11 votes for B go to their respective second choices.
#### Vote Redistribution
The 11 votes are redistributed to candidate C.
#### Tally After First Elimination
- A: 1210 votes
- C: 36 votes (25 + 11)
- D: 8 votes
### Second Elimination
Now, candidate D has the fewest votes (8 votes).
#### Vote Redistribution
The 8 votes are redistributed to their second choices. In this scenario, they would move to their respective second choices in a preferential election.
Since 'D' voters second choice is C, The votes of D are added to C.
#### Tally After Second Elimination
- A: 1210 votes
- C: 44 votes (36 + 8)
### Final Preference Table After Eliminations
This results in a redistribution as follows:
\begin{tabular}{|c|c|c|}

\multicolumn{2}{|l|}{ Final Vote Redistribution } \\

Thus, initially A has 1210 votes, B has 11 (shifted to C), C has 25 (and increased after redistribution), and D has 8 (moved to C). Ultimately, candidate A wins by the plurality-with-elimination method with 1210 votes against C's 44.
