Why These Connect
The narrative assertion
"The Doctor examining floor plans of the old Kaled city (INT. DALEK CONTROL, beat_0ae83ba094de0df3) reveals the puzzling absence of a fourth level plan (INT. DALEK CONTROL, beat_c0229b4d7bada1ff), which directly leads to his hypothesis about a hidden shaft."
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.
