Q: Passage: After the War of Independence and truce called in July 1921, representatives of the British government and the Irish treaty delegates, led by Arthur Griffith, Robert Barton and Michael Collins, negotiated the Anglo-Irish Treaty in London from 11 October to 6 December 1921. The Irish delegates set up headquarters at Hans Place in Knightsbridge, and it was here in private discussions that the decision was taken on 5 December to recommend the treaty to Dáil Éireann.The Second Dáil Éireann narrowly ratified the Treaty. In accordance with the treaty, on 6 December 1922 the entire island of Ireland became a self-governing Dominion called the Irish Free State . Under the Constitution of the Irish Free State, the Parliament of Northern Ireland had the option to leave the Irish Free State one month later and return to the United Kingdom. During the intervening period, the powers of the Parliament of the Irish Free State and Executive Council of the Irish Free State did not extend to Northern Ireland. Northern Ireland exercised its right under the treaty to leave the new Dominion and rejoined the United Kingdom on 8 December 1922. It did so by making an address to the King requesting, "that the powers of the Parliament and Government of the Irish Free State shall no longer extend to Northern Ireland." The Irish Free State was a constitutional monarchy sharing a monarch with the United Kingdom and other Dominions of the British Commonwealth. The country had a governor-general , a bicameral parliament, a cabinet called the "Executive Council", and a prime minister called the President of the Executive Council.
Question: What happened second, Ireland became a self-governing Dominion called the Irish Free State or Ireland rejoining the UK?

Q: Passage: In February 1865 Brahmss mother died, and he began to compose his large choral work A German Requiem Op. 45, of which six movements were completed by 1866. Premieres of the first three movements were given in Vienna, but the complete work was first given in Bremen in 1868 to great acclaim. A seventh movement (the soprano solo "Ihr habt nun Traurigkeit") was added for the equally successful Leipzig premiere (February 1869), and the work went on to receive concert and critical acclaim throughout Germany and also in England, Switzerland and Russia, marking effectively Brahmss arrival on the world stage. Brahms also experienced at this period popular success with works such as his first set of Hungarian Dances (1869), the Liebeslieder Walzer, Op. 52 (Brahms), (1868/69), and his collections of lieder (Opp. 43 and 46–49). Following such successes he finally completed a number of works that he had wrestled with over many years such as the cantata Rinaldo (cantata) (1863–1868), his Two String Quartets, Op. 51 (Brahms) Op. 51 nos. 1 and 2 (1865–1873), the third piano quartet (1855–1875), and most notably his Symphony No. 1 (Brahms) which appeared in 1876, but which had been begun as early as 1855.
Question: How many years after Brahmss mother died, were the complete work given in Bremen?

A: number
