Why These Connect
The narrative assertion
"The Doctor's inquiry about the recycling shaft's purpose (a disused waste conduit for war materials) directly leads to the Marshal's later attempt to shut it down and dispose of K9 within it. The shaft's hazardous design mirrors the Marshal's brutal prioritization of war resources over life."
About Causal Connections
A directly causes B. The first event sets forces in motion that produce the second. These are the load-bearing connections of plot--remove one and the story structure collapses.
