[Q]: Passage: Calvin Coolidge (born John Calvin Coolidge Jr.; ; July 4, 1872 – January 5, 1933) was an American politician and lawyer who served as the 30th president of the United States from 1923 to 1929. A Republican lawyer from New England, born in Vermont, Coolidge worked his way up the ladder of Massachusetts state politics, eventually becoming governor of Massachusetts. His response to the Boston Police Strike of 1919 thrust him into the national spotlight and gave him a reputation as a man of decisive action. The next year, he was elected vice president of the United States, and he succeeded to the presidency upon the sudden death of Warren G. Harding in 1923. Elected in his own right in 1924, he gained a reputation as a small government conservative and also as a man who said very little and had a rather dry sense of humor.

[Q]: Passage: 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.
