Focus Tree Help

Hi, can someone tell me how to do one of two things:

1) Make it so that something must be false for a focus to be completed

2) Make it so that a certain choice in an event was chosen to complete the focus



I want to know how to do one of these because I'm making a focus tree where the Democratic side of the Harita's State "Unite the World" has two focuses after The Question of Paraguay: Violence and Peace. With Peace, it's pretty simple. It would be 

Controls state: Paraguay


However, the other, Violence, is a little trickier -

One of the two is what I want for it (Correlating to the previously mentioned requests):

1) Does NOT control state: Paraguay

2) Choice in an event was made: Event: boyexpand_harita_expansion.1 We will win this 3-year civil war! (In the lore of the mod, Harita rebelled in 1933; the mod intends for the event to be fired in 1936.) OR choice in an event was NOT made: Event: boyexpand_harita_expansion.1 Fine.



Also, how do I make it so that a message/warning is in the Effects list or something like that?


E.G. Chaos in Africa, in Effects, has the text: Allows for further expansion into Africa.

Aight so right after I made it, I realized I could make it so that if Paraguay still controls state: Paraguay, then Violence is chosen. If Harita's State controls it, then Peace is chosen. But still, in case I run into this issue again without such a simple solution, I still want the answer.
