I want to know the answer to the following question:
Where is Catalan the only official language?
All the background I'm provided with is that "It is also spoken with no official recognition in parts of the Spanish autonomous communities of Aragon (La Franja) and Murcia (Carche), and in the historic French region of Roussillon/Northern Catalonia, roughly equivalent to the department of Pyrénées-Orientales.". Is that enough to answer the question?
Answer: no
