Great work sir, Cant agree any less.

important something like this might help a lot

How I remember it:

A is necessary for B:

The falsity of A guarantees the falsity of B.

A is sufficient for B:

The truth of A guarantees the truth of B.

A is necessary and sufficient for B:

B is logically equivalent to A.

A is neither necessary nor sufficient for B:

B cannot be determined from A.
