Is Palawan part of Visayas or Mindanao?

Palawan is not part of Visayas or Mindanao. It is a separate island group and region called Region IV-B (MIMAROPA).

Here's a breakdown:

* Visayas: Composed of three main islands: Cebu, Bohol, and Leyte, and many smaller islands.

* Mindanao: The southernmost major island group of the Philippines.

* Palawan: A large island in the western Philippines, with many smaller surrounding islands. It's considered a distinct region, MIMAROPA, which stands for "Mimaropa" (Mindoro, Marinduque, Romblon, Palawan).
