Why These Connect
The narrative assertion
"The Doctor and Adric's approach to the hatch and their cautious checks for booby traps (beat_2f29b31511d4666e and beat_141f948282dc9c3f) leads to the hatch opening and revealing the bomb (beat_a7d167e953734a8f), triggering the arming sequence (beat_e79d5635b509c942)."
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.
