Answer:
The PLO uprising against Israel in the 1980s and again in the 1990s is commonly referred to as the First Intifada and the Second Intifada, respectively.
Step-by-step explanation:
1) The First Intifada: The First Intifada occurred from 1987 to 1993 and was a Palestinian uprising against Israeli occupation in the West Bank, Gaza Strip, and East Jerusalem. It was characterized by widespread civil disobedience, protests, strikes, and acts of violence from Palestinians against Israeli forces. The Intifada, meaning "shaking off" in Arabic, aimed to challenge Israeli control and assert Palestinian national identity and self-determination.
