I want to know the answer to the following question:
What is its largest island?
All the background I'm provided with is that "Located in the North-West of the Iberian Peninsula, it comprises the provinces of A Coruña, Lugo, Ourense and Pontevedra, being bordered by Portugal to the south, the Spanish autonomous communities of Castile and León and Asturias to the east, and the Atlantic Ocean to the west and the north.". Is that enough to answer the question?
Answer: no
