Question: Which area of the district is larger, Topchanchi or Tundi? Passage 1:Sinopoli was drafted 29th overall in the fourth round of the 2011 CFL Draft by the Calgary Stampeders. He was later signed to a contract with the Stampeders on May 20, 2011. He dressed in all 18 regular season games for the 2011 season as the third-string quarterback as well as dressing in the West Semi-Final. Sinopoli served as the team's holder for placekicks in all of their games as well. Prior to the start of the 2012 regular season, Sinopoli was released by the Stampeders. Following an injury to Calgary's starting quarterback Drew Tate, Sinopoli was re-signed by the Stampeders on July 9, 2012. Thereafter, Sinopoli dressed for ten games as the third-string quarterback before Tate went back on the active roster. Following another injury to Tate, Sinopoli dressed in the West Final and 100th Grey Cup. Due to the entrenched quarterbacks on the depth chart, Sinopoli was moved to wide receiver for the 2013 CFL season, with his first career reception coming against the Montreal Alouettes. Sinopoli recorded his first CFL touchdown on a 26-yard run in a 10–7 victory over the Hamilton Tiger-Cats on July 18, 2014. He finished the 2013 season with 34 receptions and 417 receiving yards in 14 regular season games played.

 Passage 3:Dhanbad district forms a part of the Chota Nagpur Plateau, but it is more of an upland than a plateau. The district has two broad physical divisions – the southern part is a coal mining area with mining and industrial towns, and the northern part has villages scattered around hills. The landscape of the southern part is undulating and monotonous, with some scars of subsidence caused by underground mining. One of the many spurs of Parashnath Hills (1,365.50 m), in neighbouring Giridih district, passes through the Topchanchi and Tundi areas of the district. The spur attains a height of 457.29 m but there is no peak as such. The Dhangi Hills (highest peak 385.57 m) run from Pradhan Khunta to Gobindpur. While the main river Damodar flows along the southern boundary, its tributary, the Barakar, flows along the northern boundary. DVC has built two dams across the rivers. The Panchet Dam is across the Damodar and the Maithon Dam is across the Barakar.
