Question: Read the following paragraph and extract the answer for the question: Where did the Cascade Locks and Canal enable boats to travel safely through?  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...
Answer: the Columbia River Gorge

[Q]: Read the following paragraph and extract the answer for the question: What was the shipwright's other business?  In the early 1660s, a building program was initiated to expand the fleet and replace old capital ships. A new flagship was needed to replace the old Kronan from 1632. The felling of vast quantities of timber that were required for the new admiral's ship had already begun in the winter of 1664–65. Swedish historian Kurt Lundgren has estimated that 7–10 hectares (17–25 acres) of hundred-year-old oak forest was required for the hull and several tall, stout pines for the masts and bowsprit.The construction of Kronan began in October 1665, and the hull was launched on 31 July 1668. The English shipwright Francis Sheldon frequently came in conflict with the admiralty over the project. The navy administrators complained that he was unduly delaying the project and was spending too much time on his own private business ventures. The most aggravating contention was Sheldon's extensive and lucrative export of mast timber to England. Sheldon in turn complained about constant delays on the navy's part and lack of funds. When the ship was launched, the slipway turned out to be too small and the rear section of the keel broke off during the launching. The admiralty demanded an explanation, but Sheldon's reply was that the damage was easily mended and that the problem was that the timber had been left to dry too long. The conflict between the Admiralty and Sheldon dragged on for several years and caused constant delays. The sculptures were finished in 1669, but the rigging, tackling, and arming was drawn out a further three years, to 1672. The first occasion that the ship sailed was during the celebrations of Charles XI's accession as monarch in December 1672.

input: Please answer the following: Read the following paragraph and extract the answer for the question: What island did Amelia Earhart crash her Lockheed Electra on?  During the 1930s, the Navy contracted a $1.5 million dredging of Pearl Harbor to allow larger battleships and the fleet's carriers to enter it. Work began in May 1940 resulting in 13,000,000 cubic yards (9,900,000 m3) of material dredged from the opening of Pearl Harbor to build a channel to Ford Island as well as to create a turning channel around the island.  Material was also dredged to deepen the West Loch, East Loch, and Middle Loch for the mooring of battleships. With dredged material used as land fill, the island's size was increased from 334 acres (135 ha) to 441 acres (178 ha).The Navy replaced its PK, F5L, and H16 aircraft with newer models (see table below). In 1933 VP-8F arrived on station, and in 1935 the army bombers had become too large to be maintained and stored at Luke Field. Construction began on a new Army airfield, Hickam Army Airfield, named after pioneer U.S. Army Air Corps pilot Lieutenant Colonel Horace Meek Hickam. From 1936 to 1940 Pan American flew its Clipper service into Ford Island, using it as a refueling stop between the United States and Asia. The Navy built a $25,000 boathouse, spent $579,565 on a new crew barracks and built a firehouse, water-supply and lighting systems. In June 1936 the Navy lengthened the island's landing field by 400 feet (120 m), to 3,000 feet (910 m). In March 1937 Amelia Earhart, on her second visit to Luke Field, crashed her Lockheed Electra on takeoff. In 1939, after three years of construction, Hickam Field opened. The Army transferred its operations there, leaving Luke Field under Navy control. The latter was renamed Naval Air Station Ford Island, and became the headquarters of Patrol Wing 2; its former namesake was re-honored with a new base, Luke Air Force Base in Arizona. A September 8, 1939, presidential emergency proclamation spurred the rapid construction of new facilities to prepare the island for additional operations. This included additional barracks, a new assembly and repair hangar, an administration building, a dispensary, a  control...
