Apply minimum spanning tree reasoning - context restriction

A transport depot minimum spanning tree has accepted edge weights 6, 4, 5, 7 after rejecting cycle-forming alternatives. Find the total connection weight. This version asks for the same mathematical quantity after confirming the method from the context. Enter the requested value and choose the interpretation that matches the result.

Worked practice: result and interpretation

Calculate the requested result first, then choose the interpretation that follows from it.
