Example Input: Question: Which of the empires that succeeded the Achaemenid Empire had the smallest number of people? 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.

Example Output: 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

Example Input: Question: Who won the battle where Hugh Mercer was killed? Passage:Fort Mercer was a fort on the Delaware River in New Jersey constructed by the Continental Army during the American Revolutionary War. Built by Polish engineer Thaddeus Kosciuszko under the command of George Washington, Fort Mercer was built in 1777 to block the approach to Philadelphia, Pennsylvania in concert with Fort Mifflin on the Pennsylvania side. Fort Mercer was located in an area called Red Bank, in what is now the borough of National Park, Gloucester County, New Jersey. The fort was named in honor of Brigadier General Hugh Mercer who had died earlier that year at the Battle of Princeton. The fort's site is now part of Red Bank Battlefield Historical Park, which includes a monument and museum. Several cannons attributed to British warships lost supporting the attack on the fort, and others found buried at the fort itself, are in the park.

Example Output: The fort was named in honor of Brigadier General Hugh Mercer who had died earlier that year at the Battle of Princeton

Example Input: Question: Did Cobble Hill Tunnel exist the year the South Ferry was established? Passage:As the City of Brooklyn grew, the area south of Atlantic Avenue, known as South Brooklyn, began to become developed, but the area lacked easy access to the ferry terminals in the northern parts of that city. To solve this problem, the South Ferry Company established the South Ferry on May 16, 1836 to connect Lower Manhattan to the foot of Atlantic Avenue in Brooklyn and the month-old Brooklyn and Jamaica Railroad (renamed Atlantic Avenue Railroad, later the Atlantic Avenue Railroad's streetcar line, later still part of the South Side Railroad of Long Island, now the Atlantic Branch of the Long Island Rail Road) through the Cobble Hill Tunnel. "South Ferry" was also the name of the Brooklyn landing and ferry house. In the 20th and early 21st centuries, the Brooklyn landing site served cargo as Brooklyn Piers 5 and 6, now part of Brooklyn Bridge Park
