Question: Which of Kuroda's contemporaries had more championships, Hosaka or Tanaka? Passage:Kuroda began his professional wrestling career in January 1993, when he was trained by Pro Wrestling Crusaders (PWC) at their dojo and made his debut on March 18, 1993 against Hideki Hosaka. PWC closed after a few months and Kuroda resumed his training at the Frontier Martial-Arts Wrestling (FMW) dojo. He made his FMW debut as a fan favorite with Masato Tanaka by losing to Dark Ranger and Masaru Toi in a tag team match on October 15. Kuroda remained in the low card for many years in the company and was usually utilized in opening matches on the card and served as a enhancement talent against higher level opponents, winning against only lesser known talent. He was often paired with fellow newcomer Tanaka in mid-card matches during the early years of his career and often wrestled Tanaka, Koji Nakagawa and Gosaku Goshogawara. Kuroda's first main event match took place on November 26, 1994, when he teamed with Atsushi Onita, Katsutoshi Niiyama and Masato Tanaka to defeat Mr. Pogo, The Gladiator, Hideki Hosaka and Hisakatsu Oya in a no ropes barbed wire street fight deathmatch. Kuroda would team with Onita, Niiyama and Tanaka in several street fights during late 1994 and early 1995. In the summer of 1995, Kuroda was entered into the Young Spirit Tournament, a round robin tournament consisting of rising rookies of the company. He would lose all of his matches in the tournament against W*ING Kanemura, Hideki Hosaka, Koji Nakagawa and Hido, while wrestling Masato Tanaka to a double knockout to gain one point in the tournament.

Question: Which dam was built last? Passage: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.
