[Q]: This article: 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... contains an answer for the question: What event took place that disrupted Portland's economy in 1980?, what is it ?

[Q]: This article: One of the Orb's most notable contributions to electronic music is their idea of blurring the distinction between sampling and remixing. Albums such as Pomme Fritz, though released as a piece of original work, consist largely of manipulated samples. Conversely, the Orb's remixes typically use only small sections of the original track, most notably in the case of their single "Toxygene". "Toxygene" was originally commissioned as a remix of Jean Michel Jarre's "Oxygene 8" from Oxygene 7-13. The Orb "obliterated it" and reassembled only a few fragments for their remix, much to the chagrin of Jarre, who reportedly refused to release it; The Orb released the track themselves under the name "Toxygene", which further irritated Jarre, to whom Paterson retorted "The French are always five years behind us, anyway." In statements made after the release of "Toxygene", Jarre denied that he rejected the original remix because of disliking it.Other artists have become agitated due to the Orb sampling their work, though Paterson jokingly suggests that "[t]hey don't know the half of it." Paterson says that he finds a "beauty" and a "cleverness" with slipping unlicensed samples into compositions without anyone recognizing it. Even though fans often try to guess the origins of many of the samples, Paterson states that they are rarely correct and that they would "die" if they discovered, for example, where the drums on "Little Fluffy Clouds" originated from. He has said that record labels have cautioned him, "Don't tell anyone where you got your samples until we get them cleared!". contains an answer for the question: What is the first name of the person who was irritated by the release of Toxygene?, what is it ?

[A]: Jean

[Q]: This article: Elgar is probably best known for the first of the five Pomp and Circumstance Marches, which were composed between 1901 and 1930. It is familiar to millions of television viewers all over the world every year who watch the Last Night of the Proms, where it is traditionally performed. When the theme of the slower middle section (technically called the "trio") of the first march came into his head, he told his friend Dora Penny, "I've got a tune that will knock 'em – will knock 'em flat". When the first march was played in 1901 at a London Promenade Concert, it was conducted by Henry J. Wood, who later wrote that the audience "rose and yelled ... the one and only time in the history of the Promenade concerts that an orchestral item was accorded a double encore." To mark the coronation of Edward VII, Elgar was commissioned to set A. C. Benson's Coronation Ode for a gala concert at the Royal Opera House in June 1901. The approval of the king was confirmed, and Elgar began work. The contralto Clara Butt had persuaded him that the trio of the first Pomp and Circumstance march could have words fitted to it, and Elgar invited Benson to do so. Elgar incorporated the new vocal version into the Ode. The publishers of the score recognised the potential of the vocal piece, "Land of Hope and Glory", and asked Benson and Elgar to make a further revision for publication as a separate song. It was immensely popular and is now considered an unofficial British national anthem. In the United States, the trio, known simply as "Pomp and Circumstance" or "The Graduation March", has been adopted since 1905 for virtually all high school and university graduations.In March 1904 a three-day festival of Elgar's works was presented at Covent Garden, an honour never before given to any English composer. The Times commented, "Four or five years ago if any one had predicted that the Opera-house would be full from floor to ceiling for the performance of an oratorio by an English composer he would probably have been supposed to be out of his... contains an answer for the question: What was conducted by Henry Wood when it was played at a London Promenade Concert?, what is it ?
