Example Input: Question: What cities were the two founders of the Communist Party of China from? Passage:The Republic of China was founded by the Kuomintang (KMT) leader Dr. Sun Yat-sen in 1912. The Kuomintang's prior revolutionary political group, the Revive China Society, was founded on 24 November 1894. It later merged with various other revolutionary groups to form the Tongmenghui in 1905. In August 1911, the Tongmenghui further merged with various other political parties in Beijing to form the KMT. In July 1914, the KMT re-organized itself as the "Chinese Revolutionary Party" in Tokyo, Japan. In 1919, the party officially renamed itself as "Kuomintang of China", which literally translates to "Chinese Nationalist Party". It was China's first major political party. In 1921, the Communist Party of China (CPC) was founded by Chen Duxiu and Li Dazhao in Shanghai as a study society and an informal network. Slowly, the CPC began to grow. These were the two major political parties in China, during the time when the ROC ruled mainland China from 1911 to 1949.

Example Input: Question: How long has the military facility been in operation on San Nicolas Island? Passage:San Nicolas Island (Tongva: Haraasnga) is the most remote of California's Channel Islands, located 61 miles (98 km) from the nearest point on the mainland coast. It is part of Ventura County. The 14,562 acre (58.93 km or 22.753 sq mi) island is currently controlled by the United States Navy and is used as a weapons testing and training facility, served by Naval Outlying Field San Nicolas Island. The uninhabited island is defined by the United States Census Bureau as Block Group 9, Census Tract 36.04 of Ventura County, California. The Nicoleño Native American tribe inhabited the island until 1835. As of the 2000 U.S. Census, the island has since remained officially uninhabited, though the census estimates that at least 200 military and civilian personnel live on the island at any given time. The island has a small airport, though the 10,000 foot runway is the second longest in Ventura County (slightly behind the 11,102 ft. at the Naval Air Station Point Mugu). Additionally, there are several buildings including telemetry reception antennas.
