1. Read this first

   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.

5. 4.

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

   • Granary first: the harvest comes before the boats
   • Dock first: it needs fewer workers than the granary
   • Dock first: boats matter more to a city than grain
   • Both at once: Dunmar can borrow the missing workers
6. 5.

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

   • Disagree: nothing is given up either way
   • Agree: the project with fewer workers should go first
   • Agree: the dock is due before the harvest comes
   • Weigh the deadlines too: the granary is due first
7. 6.

   Which statement about the dock is right, Kira asks?

   • It is the resource that Dunmar uses up first
   • It is built at once, so Dunmar gives up nothing
   • It is built next, with the 20 workers who are left
   • It waits a year, and that is the opportunity cost
