input question: Given the below context:  As early as 1881, industrialists proposed altering the natural channel of the Columbia to improve navigation. Changes to the river over the years have included the construction of jetties at the river's mouth, dredging, and the construction of canals and navigation locks. Today, ocean freighters can travel upriver as far as Portland and Vancouver, and barges can reach as far inland as Lewiston, Idaho.The shifting Columbia Bar makes passage between the river and the Pacific Ocean difficult and dangerous, and numerous rapids along the river hinder navigation. Pacific Graveyard, a 1964 book by James A. Gibbs, describes the many shipwrecks near the mouth of the Columbia. Jetties, first constructed in 1886, extend the river's channel into the ocean. Strong currents and the shifting sandbar remain a threat to ships entering the river and necessitate continuous maintenance of the jetties. In 1891 the Columbia was dredged to enhance shipping. The channel between the ocean and Portland and Vancouver was deepened from 17 feet (5.2 m) to 25 feet (7.6 m). The Columbian called for the channel to be deepened to 40 feet (12 m) as early as 1905, but that depth was not attained until 1976.Cascade Locks and Canal were first constructed in 1896 around the Cascades Rapids, enabling boats to travel safely through the Columbia River Gorge. The Celilo Canal, bypassing Celilo Falls, opened to river traffic in 1915. In the mid-20th century, the construction of dams along the length of the river submerged the rapids beneath a series of reservoirs. An extensive system of locks allowed ships and barges to pass easily from one reservoir to the next. A navigation channel reaching to Lewiston, Idaho, along the Columbia and Snake rivers, was completed in 1975. Among the main commodities are wheat and other grains, mainly for export. As of 2016, the Columbia ranked third, behind the Mississippi and Paraná rivers, among the world's largest export corridors for grain.The 1980 eruption of Mount St. Helens caused mudslides in the area, which...

input question: Given the below context:  Buckton was a small highland enclosure castle with a 2.8-metre-thick (9 ft) sandstone curtain wall; nothing survives above ground. It is roughly oval and measures 35.6 by 26.2 metres (117 by 86 ft), covering an area of 730 square metres (0.18 acres). The castle is surrounded by a 10-metre-wide (33 ft) ditch apart from the south-west part where the steep slope of the hill makes the ditch unnecessary. When the ditch was dug some of the material was used to raise the interior of the castle by 1.5 metres (4 ft 11 in).Buckton is similar in size to Clitheroe Castle's inner enclosure, which is also oval (31.8 by 26 metres (104 by 85 ft)) and has a 2.6-metre-thick (9 ft) curtain wall. Clitheroe was also built on a rocky peak and the small size of its great tower may be due to its naturally defensible position and location in an economically deprived area.Buckton Castle was entered through a gatehouse in the north-west measuring 9.3 by 7.5 metres (31 by 25 ft). The east side was occupied by the gate passage and the west by a chamber. Though the structure no longer survives above ground, it was probably at least two storeys tall. Constructed in the 12th century, Buckton's gatehouse was the earliest in North West England, and was one of six stone gatehouses in the region that were built in the 12th or 13th centuries: Buckton, Egremont, Brough, Clitheroe, Carlisle's inner gatehouse, and the Agricola Tower at Chester. They are broadly similar in size, and take the form of a gate passage piercing a single tower with rooms in the floors above. Buckton's gatehouse differs slightly in having the passage offset to one side.In the 1770s, the antiquarian Thomas Percival recorded a well within the castle, close to the south curtain, and walls of buildings inside the castle still standing to a height of 2 metres (7 ft). A plan created by the Saddleworth Geological Society in 1842 recorded a ruined structure within the castle's south-east area in addition to the well Percival noted. Trenches in the castle's interior did not reveal...  Guess a valid title for it!???

input question: Given the below context:  The Kingdom of Mysore reached a peak in economic power under Hyder Ali and Tipu Sultan, in the post-Mughal era of the mid-late 18th century. They embarked on an ambitious program of economic development, aiming to increase the wealth and revenue of Mysore. Under their reign, Mysore overtook the Bengal Subah as India's dominant economic power, with productive agriculture and textile manufacturing.Tipu Sultan is credited with founding state trading depots in various locations of his kingdom. In addition, he founded depots in foreign locations such as Karachi, Jeddah and Muscat, where Mysore products were sold. During Tipu's rule French technology was used for the first time in carpentry and smithing, Chinese technology was used for sugar production, and technology from Bengal helped improve the sericulture industry. State factories were established in Kanakapura and Taramandelpeth for producing cannons and gunpowder respectively. The state held the monopoly in the production of essentials such as sugar, salt, iron, pepper, cardamom, betel nut, tobacco and sandalwood, as well as the extraction of incense oil from sandalwood and the mining of silver, gold and precious stones. Sandalwood was exported to China and the Persian Gulf countries and sericulture was developed in twenty-one centers within the kingdom.The Mysore silk industry was initiated during the rule of Tipu Sultan. Later the industry was hit by a global depression and competition from imported silk and rayon. In the second half of the 20th century, it however revived and the Mysore State became the top multivoltine silk producer in India.Under Tipu Sultan, Mysore enjoyed one of the world's highest real wages and living standards in the late 18th century, higher than Britain, which in turn had the highest living standards in Europe. Mysore's average per-capita income was five times higher than subsistence level, i.e. five times higher than $400 (1990 international dollars), or $2,000 per capita. In comparison, the highest national per-capita incomes...  Guess a valid title for it!???
