Question: How many wrestlers did the NJPW have the year Takaiwa passed his entry exam? Passage 1:T2 was a seagoing torpedo boat that was operated by the Royal Yugoslav Navy between 1921 and 1941. Originally 77 T, a 250t-class torpedo boat of the Austro-Hungarian Navy built in 1913–1914, she was armed with two guns and four torpedo tubes, and could carry 10–12 naval mines. She saw active service during World War I, performing convoy, patrol, escort, minesweeping and minelaying tasks, anti-submarine operations, and shore bombardment missions. Following Austria-Hungary's defeat, 77 T was allocated to the Navy of the Kingdom of Serbs, Croats and Slovenes, which became the Royal Yugoslav Navy, and was renamed T2. At the time, she and seven other 250t-class boats were the only modern sea-going vessels of the fledgling maritime force. During the interwar period, T7 and the rest of the navy were involved in training exercises and cruises to friendly ports, but activity was limited by reduced naval budgets. She was scrapped in 1939.
 Passage 2:While attending vocational school, Takaiwa passed the New Japan Pro Wrestling (NJPW) entry exam and began training with the promotion in 1992. Takaiwa was part of the same trainee class as Shinjiro Otani and the two became frequent opponents and tag team partners when they eventually debuted. Takaiwa debuted on July 21, 1992, losing to Satoshi Kojima. In 1993, Takaiwa took part in the Young Lions Cup, finishing last with zero wins and zero points. During the early years of his career, Takaiwa primarily competed in opening matches, usually on the losing end as is customary for young wrestlers in Japan. Beginning in 1997, Takaiwa began to create more of a name for himself, competing in that year's Best of the Super Juniors tournament and finishing with four points. In 1998, Takaiwa teamed up with Otani to take part in the league to crown the inaugural IWGP Junior Heavyweight Tag Team Champions, with the two of them defeating Koji Kanemoto and Dr Wagner Jr in the finals to become the first ever holders of the belts. In December 1998, Takaiwa received his first shot at the IWGP Junior Heavyweight Championship, unsuccessfully challenging Jushin Thunder Liger. Days later on December 11, Takaiwa and Otani travelled to Wrestle Association R where they defeated Masaaki Mochizuki and Masao Orihara to win the vacant International Junior Heavyweight Tag Team Championship, making themselves double champions. Their days as double champions didnt last long, however, as they would lose the IWGP Junior Heavyweight Tag Team Championship to Kendo Kashin and Dr Wagner Jr at Wrestling World 1999. Later in the year they would regain the championships, defeating Jushin Thunder Liger and The Great Sasuke in July. In 2000, both Otani and Takaiwa took part in the Best of the Super Juniors tournament, with both men winning their blocks and reaching the final, where, on June 9, Takaiwa defeated Otani to win the 2000 Best of the Super Juniors. Later in the month after just under a year as champions, Otani and Takaiwa lost the IWGP Junior Heavyweight Tag Team Championships to the Junior Stars (Koji Kanemoto and Minoru Tanaka). After losing the titles, Takaiwa began focusing more on his singles career, winning the IWGP Junior Heavyweight Championship for the first time in his career in July, defeating Jushin Thunder Liger. Takaiwa eventually lost the championship to Minoru Tanaka in October.
 Passage 3:In 1943 she was appointed assistant agronomist at the Waite Agricultural Research Institute in Adelaide, where she started working on native pasture species for arid and semi-arid South Australia. She was appointed to the new position of systematic botanist at the CSIRO Division of Plant Industry, Canberra in 1946. At CSIRO she worked on organising and extending the herbarium, first as a research scientist and then as curator and was responsible for laying the foundations of the Herbarium Australiense, later the National Australian Herbarium. She wrote Key to the South Australian species of Eucalyptus L'Hér. but had not specialised on the genus. Her professional interest in systemic botany was reflected by her tenure as secretary of the systematic botany committee of the Australian and New Zealand Association for the Advancement of Science from 1948 to 1952. She also edited Australasian Herbarium News until her until 1953, when she took a years leave to be the Australian Botanical Liaison Officer at the Kew Gardens herbarium. While at Kew she photographed and indexed type specimens of Australian plants and made microfilm copies of Robert Brown's notebooks for Australian herbaria.
