Problem:Question: When did the dynasty of Ekoji's half-brother begin? Passage 1:Rodrigo studied music under Francisco Antich in Valencia and under Paul Dukas at the École Normale de Musique in Paris. After briefly returning to Spain, he went to Paris again to study musicology, first under Maurice Emmanuel and then under André Pirro. His first published compositions date from 1923. In 1943 he received Spain's National Prize for Orchestra for Cinco piezas infantiles ("Five Children's Pieces"), based on his earlier composition of the same piece for two pianos, premiered by Ricardo Viñes. From 1947 Rodrigo was a professor of music history, holding the Manuel de Falla Chair of Music in the Faculty of Philosophy and Letters, at Complutense University of Madrid. Notable students include Yüksel Koptagel, Turkish composer and pianist.
 Passage 2:Abbasi's political career began after the death of his father Khaqan Abbasi in 1988. In May 1988, President Muhammad Zia-ul-Haq sacked the government of his handpicked Prime Minister, Muhammad Khan Junejo, and prematurely dissolved the National Assembly. Consequently, new parliamentary elections were called for 16 November 1988. Abbasi ran for the National Assembly seat from Constituency NA-36 (Rawalpindi-I), which had been held by his father until his death. Abassi was elected with 47,295 votes as an independent candidate. He acquired Rawalpindi's National Assembly seat for the first time at the age of 30 by defeating both Raja Zafar ul Haq, a candidate of Islami Jamhoori Ittehad (IJI), and Pakistan Peoples Party (PPP) candidate Raja Muhammad Anwar by a narrow margin. After winning the election he joined the IJI, which was newly founded in September 1988 by then Director-General of Inter-Services Intelligence to counter the PPP. His tenure as a Member of the National Assembly terminated after the National Assembly was dissolved prematurely in August 1990 following the dismissal of the government of Benazir Bhutto by President Ghulam Ishaq Khan.
 Passage 3:Thanjavur was successfully conquered in 1674 by Ekoji I (1675–84), the Maratha feudatory of the sultan of Bijapur and half-brother of Shivaji (1627/30-80) of the Bhonsle dynasty. Ekoji founded the Thanjavur Maratha kingdom which ruled Thanjavur till 1855. The Marathas exercised their sovereignty over Thanjavur throughout the last quarter of the 17th and the whole of the 18th century. The Maratha rulers patronized Carnatic music. In 1787, Amar Singh, the regent of Thanjavur, deposed the minor Raja, his nephew Serfoji II (1787–93) and captured the throne. Serfoji II was restored in 1799 with the assistance of the British, who induced him to relinquish the administration of the kingdom and left him in charge of Thanjavur fort and surrounding areas. The kingdom was eventually absorbed into British India in 1855 by the Doctrine of Lapse when Shivaji II (1832–55), the last Thanjavur Maratha ruler, died without a legitimate male heir. The British referred to the city as Tanjore in their records. Five years after its annexation, the British replaced Negapatam (modern-day Nagapattinam) with Thanjavur as the seat of the district administration. Under the British, Thanjavur emerged as an important regional centre. The 1871 India census recorded a population of 52,171, making Thanjavur the third largest city in the Madras Presidency. After India's independence, Thanjavur continued as the district headquarters.
