Question: How many groups merged to form the Tongmenghui in 1905? Passage 1:The 1992–93 season was Port Vale's 81st season of football in the English Football League, and fourth successive (36th overall) season in the Second Division. John Rudge found new stars by bringing both Ian Taylor and Paul Musselwhite to the club at a combined fee of just £40,000. His team won the pre-season TNT Tournament, and also won the Football League Trophy. In the league Vale reached third place, four points off their rivals Stoke City, who lifted the title. They reached the play-off final, but lost out 3–0 to West Bromwich Albion. They left the FA Cup and the League Cup at the Third Round and First Round stages respectively. They played five Potteries derby games, winning the League Trophy clash and the FA Cup clash after a replay, but losing both encounters in the league.
 Passage 2: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.
