### TOUGH Conditional Statement- HELP!

People never learn to program a computer by reading poorly written directions.

I take this to mean that the sufficient condition is poorly written directions and the necessary condition is never learning to program a computer.

Reworded as if/then:

If one reads poorly written directions, then they will never learn to program a computer.

Diagrammed:

poorly written directions->~program computer

Am I close?

I'm reading it as

PWD => ~PC
PC => ~PWD

It doesn't say ONLY people who read poorly written directions never learn how to program a computer.
