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.

Question: Who was the founder of the railroad? Passage:The original train track through Irwindale were built by the Los Angeles and San Gabriel Valley Railroad. The Gold line uses the old right of way of the Los Angeles and San Gabriel Valley Railroad who built the first train tracks through Irwindale in 1887. The Los Angeles and San Gabriel Valley Railroad was founded in 1883, by James F. Crank with the goal of bringing a rail line to San Gabriel Valley from downtown Los Angeles. Los Angeles and San Gabriel Valley Railroad was sold on May 20, 1887 into the California Central Railway. In 1889 the rail line was consolidated into Southern California Railway Company. On Jan. 17, 1906 Southern California Railway was sold to the Atchison, Topeka and Santa Fe Railway and called the Pasadena Subdivision. Amtrak-Santa Fe ran the Southwest Chief and Desert Wind over this line through Irwindale, but relocated the Desert Wind to the Fullerton Line in 1986. The Santa Fe line served the San Gabriel Valley until 1994, when the 1994 Northridge earthquake weakened the bridge in Arcadia and the track was closed till the Gold line was built. The rail line crosses the San Gabriel River on a long girder bridge, then passes through the Santa Fe Dam Recreation Area (how it received its name). The rail line intersected the north end of the former SP Azusa Industrial Track at Irwindale (MP 118.2). Irwindale had a 6,165 foot rail siding that passed the Miller Brewing Company's Irwindale brewery. From there the tracks continued and crossed beneath Irwindale Avenue.

question:
Question: What is the maximum length of the species that is known to prey on the crossback stingaree? Passage:The broadnose sevengill shark (Notorynchus cepedianus) is known to prey on the crossback stingaree. When threatened, this ray raises its tail warningly above its body in a scorpion-like fashion. Parasites documented from this species include a tapeworm in the genus Acanthobothrium, and the monogenean Calicotyle urolophi. Like other stingrays, the crossback stingaree is aplacental viviparous: when the developing embryos exhaust their supply of yolk, their mother provisions them with nutrient-rich histotroph ("uterine milk") through specialized extensions of the uterine epithelium called "trophonemata". Females produce litters of 1–4 pups every other year. Embryonic development proceeds rapidly over a six-month period, though the total gestation period may be much longer if there is a period of dormancy for the eggs after fertilization, as has been reported in other stingarees. Off Tasmania, large estuaries such as at the mouth of the River Derwent serve as nursery areas.
