I want to know the answer to the following question:
What was Captain Byron doing when he visited Tuvalu?
All the background I'm provided with is that "Keith S. Chambers and Doug Munro (1980) identified Niutao as the island that Francisco Mourelle de la Rúa sailed past on 5 May 1781, thus solving what Europeans had called The Mystery of Gran Cocal.". Is that enough to answer the question?
Answer: no
