Final answer:
Quebec, Catalonia, Kurdistan, and Scotland are all regions with separatist movements aspiring towards self-determination to protect their unique cultural identities within larger political entities.
Step-by-step explanation:
Quebec, Catalonia, Kurdistan, and Scotland all share commonalities as regions with strong separatist movements and distinct cultural identities.
These regions seek various forms of self-determination, whether it is greater autonomy within the existing national structure or outright independence.
These movements are rooted in the desire to preserve unique languages, cultures, and historical legacies that residents feel are under threat within the larger political entities of Canada, Spain, Iraq/Iran/Turkey/Syria, and the United Kingdom, respectively.
