For a necessary condition statement "B if only A", we can write as ( B --> A), i.e. B can prove A.

(1) the thing the necessary condition for occurs à the necessary condition is met

(B -> A)

(2) the necessary condition is not met à the thing the necessary condition for does not occur

(~A --> ~B)

WRONG
