Example Input: Question: What country is the Bristol Channel located in? Passage:Because of the natural layout of the harbour, Ilfracombe became a significant safe port (registered port of refuge) on the Bristol Channel. It also had trade routes between Kinsale and Tenby, which made the port stronger. In 1208 it was listed as having provided King John with ships and men to invade Ireland; in 1247 it supplied a ship to the fleet that was sent to conquer the Western Isles of Scotland; 6 ships, with 79 men were sent to support the siege of Calais. Ilfracombe was the last disembarkation point for two large forces sent to subdue the Irish. The building which sits on Lantern Hill by the harbour, known as St Nicholas's Chapel (built 1361) is reputed to be the oldest working lighthouse in the UK; a light/beacon has been there for over 650 years. The town was also home to the Bowen family. James Bowen was master of HMS Queen Charlotte, the flagship of Richard, Earl Howe at the 1794 "Glorious First of June" battle. James Bowen was commissioned by Howe for his leadership in the battle, he rose through the levels - commander of the Argot, the Dreadnought, and in Georgian England titled "defender of Madeira", led the fleet which rescued the British army at Corunna in the Peninsula war, and retired as a Rear Admiral, Commissioner of the Royal Navy. Captain Richard Bowen (1761–1797) James Bowen's younger brother, a British naval commander on the ship HMS Terpsichore, served under Lord Nelson, and was killed at the battle of Santa Cruz de Tenerife. John Bowen (1780–1827), son of James Bowen, a naval officer and colonial administrator founded the first settlement of Tasmania at Risdon Cove in 1803 - the settlement which later became known as Hobart. Lieutenant A E Down, was initially posted to Ilfracombe to lead a protection ship for the customs and excise, he married a local girl, rose through the levels to retire as vice Admiral, his son joined the navy aged 14 (his first navy kit is on display at National Maritime Museum Greenwich). In 1802 James Meek married Down's daughter and settled in the town, James Meek was appointed the Comptroller of Victuals to the Royal Navy in 1832, he was knighted, and died in Ilfracombe 1852.

Example Input: Question: During what years was the Early Bronze Age? Passage:Iran is home to one of the world's oldest continuous major civilizations, with historical and urban settlements dating back to 7000 BC. The south-western and western part of the Iranian Plateau participated in the traditional Ancient Near East with Elam, from the Early Bronze Age, and later with various other peoples, such as the Kassites, Mannaeans, and Gutians. Georg Wilhelm Friedrich Hegel calls the Persians the "first Historical People". The Medes unified Iran as a nation and empire in 625 BC. The Achaemenid Empire (550–330 BC), founded by Cyrus the Great, was the first true global superpower state and it ruled from the Balkans to North Africa and also Central Asia, spanning three continents, from their seat of power in Persis (Persepolis). It was the largest empire yet seen and the first world empire. The Achaemenid Empire was the only civilization in all of history to connect over 40% of the global population, accounting for approximately 49.4 million of the world's 112.4 million people in around 480 BC. They were succeeded by the Seleucid, Parthian, and Sasanian Empires, who successively governed Iran for almost 1,000 years and made Iran once again as a leading power in the world. Persia's arch-rival was the Roman Empire and its successor, the Byzantine Empire.
