Why These Connect
The narrative assertion
"The Doctor learning that the vampires can only be destroyed by a 'mighty bolt of steel' through the heart (beat_0095d7ca200423f2) leads to his realization and decision to use the magnetic card system to access the Record of Rassilon (beat_7451b8f2a22171ac), showing his adaptation to new information."
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.
