Okay, the user wants me to translate "power-base" into Ukrainian. Let me check the rules again. The first rule says to translate all content into Ukrainian. The second rule mentions if it's already in Ukrainian, leave it as is. The third rule is to provide only the translation without explanations.
So, "power-base" is in English. I need to translate it. The direct translation would be "підстава влади" or maybe "фундамент влади". Wait, "power" here could be "влада" and "base" as "підстава" or "фундамент". Which is more appropriate? "Підстава" is more like a basis or foundation, while "фундамент" is foundation. Both are possible. Maybe "підстава влади" is better. Let me confirm. Yes, "power-base" is often translated as "підстава влади" in Ukrainian. So the correct translation should be "підстава влади". I'll make sure there are no typos and that it's in Ukrainian. Since the original wasn't in Ukrainian, I need to provide the translation without any extra text.
