Input: Consider Input: Question: How long did Aulus Plautius live after capturing the lands south of the River Trent? Passage 1:The general outline of the Roman conquest of Britain during the 1st century AD is recorded by historical sources; for the involvement of specific forts historians depend on archaeological excavations. This part of Britain was occupied by a tribe known as the Cornovii. In AD 46–47 the Roman Army led by governor Aulus Plautius had probably occupied the lands to the south of the River Trent. Late in 47 the new governor of Britain, Ostorius Scapula, began a campaign against the tribes of the western mountains (modern Wales). Caratacus, their leader, was defeated in battle in AD 50 and fled to the Brigantes who occupied the Pennines. Their queen, Cartimandua, came to terms with the Romans and handed Caratacus over to them. Ostorius died and was replaced by Aulus Gallus who brought the Welsh borders under control but did not move further north or west. It was at about this time that the fort at Strutt's Park was built. It probably lay not far south of the border between Roman territory and that held by the Brigantes, who were now an allied or subject kingdom.

Input: Consider Input: Question: How much time passed between Jingaku Takashi first joined the Izutsu stable and Terao joining the same stable? Passage 1:Sassari is located in north-western Sardinia, at above sea level. The area rises up on a wide karstic plateau that slopes gently down towards the Gulf of Asinara and the Nurra plain. The city is surrounded by a green belt of thousands of hectares of olive plantations, which from the 19th century have partly replaced the mixed woodlands of oak and other Mediterranean trees as well as the maquis shrubland. The thinly populated Nurra Plain, located to the west, occupies the main part of the region of Sassari, while the urban agglomeration, with a population of about 275,000 inhabitants, is located to the south east. The abundance of water, with about 400 springs and artesian wells, has made for much development of horticulture over the centuries.
 Passage 2:Pallikaranai wetland is a freshwater marsh in the city of Chennai, India. It is situated adjacent to the Bay of Bengal, about south of the city centre, and has a geographical area of . Pallikaranai marshland is the only surviving wetland ecosystem of the city and is among the few and last remaining natural wetlands of South India. It is one of the 94 identified wetlands under National Wetland Conservation and Management Programme (NWCMP) operationalised by the Government of India in 1985–86 and one of the three in the state of Tamil Nadu, the other two being Point Calimere and Kazhuveli. It is also one of the prioritised wetlands of Tamil Nadu. The topography of the swamp is such that it always retains some storage, thus forming an aquatic ecosystem. A project on 'Inland Wetlands of India' commissioned by the Ministry of Environment and Forests, Government of India had prioritised Pallikaranai marsh as one of the most significant wetlands of the country. The marsh contains several rare or endangered and threatened species and acts as a forage and breeding ground for thousands of migratory birds from various places within and outside the country. The number of bird species sighted in the wetland is significantly higher than the number at Vedanthangal Bird Sanctuary.
 Passage 3:He came from the same area of Japan as future stable-mates Sakahoko and Terao. He was fond of kendo at school. He joined Izutsu stable in 1977, and first reached a sekitori rank in July 1982 when he was promoted to the juryo division. He first made the top makuuchi division in January 1983 but posted a losing record of 4–11 and so was immediately demoted. He won promotion back to the top division in January 1984, and remained there for virtually all of the rest of his career. In September 1984 he defeated a yokozuna for the first time when he upset Kitanoumi in one of the latter's final tournaments. He made the sanyaku ranks for the first time in November 1987 when he reached komusubi, but he proved to be out of his depth and scored only two wins against thirteen losses. He made komusubi once more in September 1990 at the age of 30, but again struggled, winning only three bouts. He suffered from stage fright, losing weight during tournaments because of stomach upsets. This affected his performance against top ranked wrestlers – he stumbled out of the dohyo in a match against Hokutoumi in September 1990 with his opponent barely having to touch him. He was restricted by a foot problem as well as digestive illness towards the end of his career. After 46 consecutive tournaments in the top division he was demoted to juryo after scoring only 4-11 at maegashira 15 in the July 1991 tourney, and he pulled out of the following tournament with a knee injury after fighting only one match. This brought to an end his streak of 1036 consecutive matches from sumo entry. He announced his retirement shortly afterwards.
