Alors pour le PowerPoint et l'image à choisir je ne peux pas aider, mais pour faire un texte pour essayer de convaincre les gens ça je peux:
Today is 2021, and no woman has ever been printed on a bill, today we want to change this ! Achieving gender equality must also go through this, and if we want to put this woman on a $20 bill it's because it's a banal bill, it doesn't have a low value like the one of 5$, but we don't mean either that the woman is worth $200 or $500, the woman is the equal of the man.
It seemed necessary to us to choose this woman as a symbol (put the name of the woman chosen here) because she is the very representation of feminine equality, and of the efforts made by women to be considered as such.
J'espère que ceci te convient
