Question: How many groups merged to form the Tongmenghui in 1905? 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: What is the population of the country where Imelda May's fifth studio album was first released? Passage:Life Love Flesh Blood is the fifth studio album by Irish singer-songwriter Imelda May. It was first released in the Republic of Ireland on 7 April 2017, through label Decca Records, followed by a worldwide release two weeks later on 21 April 2017. The album, a follow-up to May's previous album Tribal (2014), was created in collaboration with American musician T Bone Burnett. Serving as the primary producer for the record, Burnett was only credited alongside Scottish producer Cam Blackwood. Blackwood produced a duet version of the album's lead single "Call Me", recorded with English vocalist Jack Savoretti, included on streaming editions of the album post-release. Throughout the album's creative process, May received guidance from Irish musician Bono, of rock group U2. The album followed May's divorce from guitarist Darrel Higham, influencing many lyrical themes on the album. Life Love Flesh Blood features soft rock and acoustic styles, differing significantly from the rockabilly genre of previous albums.
