[Q]: Read the following paragraph and extract the answer for the question: How many species of fish are in the river that's main stem is 187 miles long and its tributaries?  The Willamette River ( (listen) wil-AM-it) is a major tributary of the Columbia River, accounting for 12 to 15 percent of the Columbia's flow. The Willamette's main stem is 187 miles (301 km) long, lying entirely in northwestern Oregon in the United States. Flowing northward between the Oregon Coast Range and the Cascade Range, the river and its tributaries form the Willamette Valley, a basin that contains two-thirds of Oregon's population, including the state capital, Salem, and the state's largest city, Portland, which surrounds the Willamette's mouth at the Columbia. Originally created by plate tectonics about 35 million years ago and subsequently altered by volcanism and erosion, the river's drainage basin was significantly modified by the Missoula Floods at the end of the most recent ice age. Humans began living in the watershed over 10,000 years ago. There were once many tribal villages along the lower river and in the area around its mouth on the Columbia. Indigenous peoples lived throughout the upper reaches of the basin as well. Rich with sediments deposited by flooding and fed by prolific rainfall on the western side of the Cascades, the Willamette Valley is one of the most fertile agricultural regions in North America, and was thus the destination of many 19th-century pioneers traveling west along the Oregon Trail. The river was an important transportation route in the 19th century, although Willamette Falls, just upstream from Portland, was a major barrier to boat traffic. In the 21st century, major highways follow the river, and roads cross it on more than 50 bridges. Since 1900, more than 15 large dams and many smaller ones have been built in the Willamette's drainage basin, 13 of which are operated by the U.S. Army Corps of Engineers (USACE). The dams are used primarily to produce hydroelectricity, to maintain reservoirs for recreation, and to prevent flooding. The river and its tributaries support 60 fish species, including many species of salmon and trout; this is despite the dams, other...

input: Please answer the following: Read the following paragraph and extract the answer for the question: When did the Artizans Company finally recover from the mismanagement and fraud of Queen's Park?  The Artizans, Labourers & General Dwellings Company (Artizans Company) was established in 1867 by William Austin. Austin was an illiterate who had begun his working life on a farm as a scarecrow paid 1 penny per day, and had worked his way up to become a drainage contractor. The company was established as a for-profit joint stock company, with the objective of building new houses for the working classes "in consequence of the destruction of houses by railroads and other improvements". The company aimed to fuse the designs of rural planned suburbs such as Bedford Park with the ethos of high-quality homes for the lower classes pioneered at Saltaire. Whilst earlier philanthropic housing companies such as the Peabody Trust and the Improved Industrial Dwellings Company focused on multi-storey blocks of flats in the inner cities, the Artizans Company aimed to build low-rise housing in open countryside alongside existing railway lines to allow workers to live in the countryside and commute into the city. The company attracted the attention of Lord Shaftesbury, who served as president until 1875. The company built and immediately sold a group of houses in Battersea, then still a rural village. The proceeds of the sale were used to purchase a plot of land in Salford for development, and by 1874 the company had developments in Liverpool, Birmingham, Gosport and Leeds.The first of the four large-scale estates built by the Artizans Company was Shaftesbury Park, a development of 1,200 two-storey houses covering 42.5 acres (0.17 km2; 0.07 sq mi) built in 1872 on the site of a former pig farm in Battersea. The success of Shaftesbury Park led to the construction of Queen's Park, built in 1874 on a far more ambitious scale on 76 acres (0.31 km2; 0.12 sq mi) of land to the west of London, adjacent to the newly opened Westbourne Park station, purchased from All Souls College, Oxford. A third London estate was planned at Cann Hall, and a site of 61 acres (0.25 km2; 0.10 sq mi) was purchased.However, the Queen's Park project...

Problem: Read the following paragraph and extract the answer for the question: What was the youngest Martha could have been when she died?  If the pigeon became alert, it would often stretch out its head and neck in line with its body and tail, then nod its head in a circular pattern. When aggravated by another pigeon, it raised its wings threateningly, but passenger pigeons almost never actually fought. The pigeon bathed in shallow water, and afterwards lay on each side in turn and raised the opposite wing to dry it.The passenger pigeon drank at least once a day, typically at dawn, by fully inserting its bill into lakes, small ponds, and streams. Pigeons were seen perching on top of each other to access water, and if necessary, the species could alight on open water to drink. One of the primary causes of natural mortality was the weather, and every spring many individuals froze to death after migrating north too early. In captivity, a passenger pigeon was capable of living at least 15 years; Martha, the last known living passenger pigeon, was at least 17 and possibly as old as 29 when she died. It is undocumented how long a wild pigeon lived.The bird is believed to have played a significant ecological role in the composition of pre-Columbian forests of eastern North America. For instance, while the passenger pigeon was extant, forests were dominated by white oaks. This species germinated in the fall, therefore making its seeds almost useless as a food source during the spring breeding season, while red oaks produced acorns during the spring, which were devoured by the pigeons. The absence of the passenger pigeon's seed consumption may have contributed to the modern dominance of red oaks. Due to the immense amount of dung present at roosting sites, few plants grew for years after the pigeons left. Also, the accumulation of flammable debris (such as limbs broken from trees and foliage killed by excrement) at these sites may have increased both the frequency and intensity of forest fires, which would have favored fire-tolerant species, such as bur oaks, black oaks, and white oaks over less fire-tolerant species, such as red oaks, thus helping to...
