   Dunmar's season (invented city)

   (an example, made up for practice), columns Project | Workers needed | Must be ready: granary | 70 | before the harvest in 3 months; dock | 60 | before the boats come in 9 months; workers Dunmar has | 90 | this season. Then, below the table: Cause and effect chain "Dunmar's shortage (invented city)": [1] Dunmar has 90 workers this season; [2] The granary needs 70 workers and the dock needs 60; [3] Both projects together need more workers than Dunmar has; [4] Dunmar cannot build both, so it builds the granary first; [5] The dock waits a year: this is the opportunity cost. Arrows: 1 → 3, 2 → 3, 3 → 4, 4 → 5. Below the chain: Dunmar is an invented city. All numbers are example data.

2. 1.

   How many workers do the granary and the dock need together, Zee asks?

   Dunmar builds the granary first. How many of its workers are left, Bo asks?

   • 40
   • 20

   • 160
4. 3.

   Which claim and reason for Dunmar's first project is strongest, Esme asks?

   • Both at once: Dunmar can borrow the missing workers
   • Dock first: boats matter more to a city than grain
   • Dock first: it needs fewer workers than the granary
   • Granary first: the harvest comes before the boats
5. 4.

   Dunmar's builders say "the dock costs less, so build it first." Which reply fits, Jun asks?

   • Agree: the dock is due before the harvest comes
   • Disagree: nothing is given up either way
   • Weigh the deadlines too: the granary is due first
   • Agree: the project with fewer workers should go first
6. 5.

   Which statement about the dock is right, Kira asks?

   • It is built at once, so Dunmar gives up nothing
   • It waits a year, and that is the opportunity cost
   • It is the resource that Dunmar uses up first

    Pia's note says, "Dunmar can build both projects with 90 workers." Which fix is right?

    • Change it: both need 130, but it has 90
    • Change 90 to 220 so that Dunmar has enough
