Task: Question Answering
Input (English): Passage: Somers and his company remained in Bermuda for 10 months, living on food they could gather on the island and fish from the sea. Some commentators believe that this incident inspired William Shakespeare's play The Tempest. During their time on the islands, the crew and passengers built a church and houses, the start of the Bermuda colony. Somers and Sir Thomas Gates oversaw the construction of two small ships, the Deliverance and the Patience. They were built from local timber  and the salvaged spars and rigging of the wrecked Sea Venture. In May 1610 the ships set sail for Jamestown, with the surviving 142 castaways on board taking food from the island. When they reached the settlement, they found it nearly destroyed by the famine and disease of what has been called the "Starving Time". Few of the supplies from the Supply Relief Fleet had arrived , and only 60 settlers survived. Only the food and help offered by those on the two small ships from Bermuda, followed by a relief fleet in July 1610 commanded by Lord Delaware, enabled the colony to survive and avoided the abandonment of Jamestown. Somers returned to Bermuda in the Patience to collect more food, but he became ill on the journey. He died in Bermuda on 9 November 1610 at age 56. Local legend says that he loved Bermuda so much that he requested that his heart be buried there. A marker in Somers' Gardens in St. George's marks the approximate location where his heart was supposed to have been buried. The remainder of his body was taken back to England and buried in his home hamlet of Whitchurch Canonicorum near to the town of Lyme Regis.
