Question: Found the following article online, use it to answer the question: What event took place that disrupted Portland's economy in 1980? 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 Parana rivers, among the world's largest export corridors for grain.The 1980 eruption of Mount St. Helens caused mudslides in the area, which...
Answer: eruption of Mount St. Helens
[Q]: Found the following article online, use it to answer the question: What is the last name of the person who enjoyed painting as much as music when they were younger? Wood was born in Oxford Street, London, the only child of Henry Joseph Wood and his wife Martha, nee Morris. Wood senior had started in his family's pawnbroking business, but by the time of his son's birth he was trading as a jeweller, optician and engineering modeller, much sought-after for his model engines. It was a musical household: Wood senior was an amateur cellist and sang as principal tenor in the choir of St Sepulchre-without-Newgate, known as "the musicians' church". His wife played the piano and sang songs from her native Wales. They encouraged their son's interest in music, buying him a Broadwood piano, on which his mother gave him lessons. The young Wood also learned to play the violin and viola. Wood received little religious inspiration at St Sepulchre, but was deeply stirred by the playing of the resident organist, George Cooper, who allowed him into the organ loft and gave him his first lessons on the instrument. Cooper died when Wood was seven, and the boy took further lessons from Cooper's successor, Edwin M. Lott, for whom Wood had much less regard. At the age of ten, through the influence of one of his uncles, Wood made his first paid appearance as an organist at St Mary Aldermanbury, being paid half a crown. In June 1883, visiting the Fisheries Exhibition at South Kensington with his father, Wood was invited to play the organ in one of the galleries, making a good enough impression to be engaged to give recitals at the exhibition building over the next three months. At this time in his life, painting was nearly as strong an interest as music, and he studied in his spare time at the Slade School of Fine Art. He remained a life-long amateur painter.After taking private lessons from the musicologist Ebenezer Prout, Wood entered the Royal Academy of Music at the age of seventeen, studying harmony and composition with Prout, organ with Charles Steggall, and piano with Walter Macfarren. It is not clear whether he was a member of Manuel Garcia's singing class, but it is certain that he...

input: Please answer the following: Found the following article online, use it to answer the question: What is the first name of the person who was introduced to the CDJ1000 turntable? During the latter half of 2002, Sasha collaborated with big beat artist Junkie XL on the single "Breezer". Junkie XL, along with Charlie May, also assisted Sasha on his second album of original material, Airdrawndagger. Airdrawndagger took several years to produce due to Sasha's desire for the album to be "as near to perfection as possible." That March, Sasha suffered a perforated eardrum in a traffic accident, further delaying the album's production. Though the accident temporarily impaired his hearing, he drew inspiration for the album from his ordeal. Airdrawndagger was finally released, in August 2002, to much fanfare. However, the album was "received with a lot of head scratching", according to Sasha, which he attributed to its unexpected mix of genres. The album did not feature the heavier "club sound" of Sasha's previous mix albums, bearing a closer resemblance to ambient music. Airdrawndagger generally received favorable reviews, though critics noted that it was not as consistent and well produced as his DJ mixes. Sasha himself described it as "a selfish, slightly self-indulgent record", though he maintains that he is "happy with it to this day". Some critics, however, called it "sleepy"; E!Online described it as being "more in league with Yanni than Moby". To encourage listeners' interest, Sasha held an amateur remix contest for the album's single, "Wavy Gravy". Due to the contest's success, Sasha released all the tracks from Airdrawndagger on his website, so that fans could download and create their own versions.After the release of Airdrawndagger, Sasha took the young DJ James Zabiela "under his wing". He introduced Zabiela to the CDJ1000 turntable, and signed Zabiela to the Excession talent agency. The two toured the United States together, which extended Sasha's influence to already-popular American DJs such as Kimball Collins. In 2004, Sasha signed with Global Underground to produce another mix album. However, he found the process of creating a standard mix album unrewarding, and decided...
