Why These Connect
The narrative assertion
"The Doctor’s confirmation that he and Turlough are in 1983 directly leads to his realization later (with the Brigadier in 1983) that the TARDIS must have gone to a different time zone, specifically 1977."
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.
