Why These Connect
The narrative assertion
"The Master's report on successful Ogron attacks on Earth cargo ships (beat_8d97481e58708186) validates the need for the Doctor's mission to find evidence of third-party involvement, which the Master later exploits to justify his traps (beat_22bc1c4ea6ebe20d)."
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.
