Chaining conditionals and contrapositives (specifically rule 6)

in Logical Reasoning 6 karma

Suppose we had a rule 6 situation where B goes to A and C goes to A, but B also goes to D and E goes to C. What happens if there are other pieces in the chain (for example, the D and E) when you take the contrapositive of the rule 6 group (A, B, C)? Do you also take the contrapositive of those? Like basically taking the contrapositive of the whole entire thing?

    Wait I'm sorry what is Rule 6? Is this referring to a specific question or something from the Core Curriculum? Not sure what Rule 6 is but just going off your chain...

    Someone correct me if I'm wrong but it seems
    B goes to A, C, D, E.
    C goes to A.

    So if you contrapose the entire thing it would be
    /A -> /C -> /B
    D and E is kind of a separate part of the chain is the way I see it.
    /D -> /B
    /E -> /B
