I want to know the answer to the following question:
Who was left on the island to recover when sick?
All the background I'm provided with is that "Though they formed no permanent settlement, the island was an important rendezvous point and source of food for ships travelling from Asia to Europe, and frequently sick mariners were left on the island to recover, before taking passage on the next ship to call on the island.". Is that enough to answer the question?
Answer: yes
