the resource requirements of different transportation methods (100 men + 400 horses

rationale: The "Exchange" domain is perfectly appropriate since transportation cost

differentials directly determine which goods can be profitably traded and over

what distances. This is fundamentally about the mechanics and feasibility of market

|

|
|
rationale: This entity has some relevance to S1 (operational constraints on primary

|
activities) and S4 (environmental factors affecting system adaptation), but it's
|
||
|
|
more of an environmental constraint than a core VSM system component. It influences

system behavior without being a control mechanism itself.

rationale: This entity provides excellent explanatory power by illuminating the

fundamental mechanism that determines market extent and specialization patterns.
|

|

It explains why certain trade relationships exist while others don't, making it
|

a key structural determinant rather than just a surface observation.

# Evaluation: Transportation Cost Differential

## definition_precision — 4.0 / 5.0
|
||
|
|
|
||
|
|
The definition clearly distinguishes between different transportation modes and their cost implications, with specific focus on water vs. land carriage. It avoids circularity and captures a distinct economic concept that directly affects market dynamics.

## source_grounding — 5.0 / 5.0
|
