The problem displayed involves four players (A, B, C, and D) dividing 12 items using the "method of markers." The goal is to determine who gets item 5 based on the players' bids.

The "method of markers" typically works by each player marking items that they believe would be a fair division of the set. Players receive items in a specific order, determined by their bids or marks.

Here’s the breakdown of bids for item 5:

• Item 5 is marked by players A and C.
• According to the method, the first item in each player's marked section is given to them. This process continues with each player's marked items until all items are assigned.

Given this setup, item 5 goes to the player who is first in the sequence. Player A is the first to bid on item 5, so it will go to Player A.

Thus, the correct answer is A. Item 5 goes to A.

Here are some related questions to think about:

1. How does the "method of markers" ensure fairness in item distribution?
2. What happens if multiple players mark the same item in the method of markers?
3. Can the method of markers be applied to more than four players?
4. What if a player marks fewer items than the others—how are their items assigned?
5. How would the outcome change if there were an odd number of items?

Tip:

In fair division problems like this, ensuring each player gets their top-ranked choices can prevent disputes. Prioritizing turns or assigning markers strategically is key.
