[EX Q]: Question: How old was the conqueror of Thanjavur in 1764? 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.

Barry is introduced as quite a goofy and kind character, who is quite brilliant at his job as a crime scene investigator for the Central City Police department. His obsession for the particle accelerator and interest in Harrison Wells began before his superhuman abilities. After the explosion that consequently led to Barry being struck by lightning, he wakes up and discovers that he has developed meta-human abilities, in particular the power of speed. This season portrays Barry's development in his superpowers, he has his setbacks in the beginning, in "Fastest Man Alive" he begins fainting, which he only finds out later that it is because his body is burning more energy than he could intake. Throughout the episode, Barry's character develops and he is able to better control his powers through training at the S.T.A.R Labs, with his team the STAR team: Caitlin Snow, Cisco Ramon and Harrison Wells. Barry's once platonic (at least to Iris West) relationship with Iris is turned complicated after all the episode "The Man in the Yellow Suit" when Barry confesses his love to her. In the episode "Crazy for You" however, Barry begins a relationship with Linda Park, who in the next episode suspects that Barry is still in love with Iris West. Over the course of the second half of the season, Barry begins to suspect and learns that Wells is actually the man in the yellow suit that killed his mother, otherwise known by his true name Eobard Thawne, whom had been manipulating events since that night to turn Barry into The Flash in an effort to harness his speed and return to the future. Eobard ultimately fails and is erased from existence by his distant ancestor, Eddie Thawne when Eddie kills himself. This provides an effort to allow Barry to travel to the past and save his mother. However, doing so results in a singularity opening above Central City which Barry then has to stop.
