Input: Oklahoma
Oklahoma is the 20th largest state in the United States, covering an area of 69,898 square miles (181,035 km2), with 68,667 square miles (177847 km2) of land and 1,281 square miles (3,188 km2) of water. It is one of six states on the Frontier Strip and lies partly in the Great Plains near the geographical center of the 48 contiguous states. It is bounded on the east by Arkansas and Missouri, on the north by Kansas, on the northwest by Colorado, on the far west by New Mexico, and on the south and near-west by Texas.

How many square miles is Oklahoma?
Output: 69,898

Input: New Haven, Connecticut
After the American Revolutionary War broke out in 1776, the Connecticut colonial government ordered the construction of Black Rock Fort (to be built on top of an older 17th-century fort) to protect the port of New Haven. In 1779, during the Battle of New Haven, British soldiers captured Black Rock Fort and burned the barracks to the ground. The fort was reconstructed in 1807 by the federal government (on orders from the Thomas Jefferson administration), and rechristened Fort Nathan Hale, after the Revolutionary War hero who had lived in New Haven. The cannons of Fort Nathan Hale were successful in defying British war ships during the War of 1812. In 1863, during the Civil War, a second Fort Hale was built next to the original, complete with bomb-resistant bunkers and a moat, to defend the city should a Southern raid against New Haven be launched. The United States Congress deeded the site to the state in 1921, and all three versions of the fort have been restored. The site is now listed on the National Register of Historic Places and receives thousands of visitors each year.

In what year did the U.S. Congress afford Connecticut the deed to the site at Fort Hale in New Haven?
Output: 1921

Input: Mandolin
Beginning with the Paris Exposition of 1878, the instrument's popularity rebounded. The Exposition was one of many stops for a popular new performing group the Estudiantes Españoles (Spanish Students). They danced and played guitars, violins and the bandurria, which became confused with the mandolin. Along with the energy and awareness created by the day's hit sensation, a wave of Italian mandolinists travelled Europe in the 1880s and 1890s and in the United States by the mid-1880s, playing and teaching their instrument. The instrument's popularity continued to increase during the 1890s and mandolin popularity was at its height in "early years of the 20th century." Thousands were taking up the instrument as a pastime, and it became an instrument of society, taken up by young men and women. Mandolin orchestras were formed worldwide, incorporating not only the mandolin family of instruments, but also guitars, double basses and zithers.

What instrument was the mandolin confused with during the 1880's? 
Output: bandurria

Input: Animal
Because of the great diversity found in animals, it is more economical for scientists to study a small number of chosen species so that connections can be drawn from their work and conclusions extrapolated about how animals function in general. Because they are easy to keep and breed, the fruit fly Drosophila melanogaster and the nematode Caenorhabditis elegans have long been the most intensively studied metazoan model organisms, and were among the first life-forms to be genetically sequenced. This was facilitated by the severely reduced state of their genomes, but as many genes, introns, and linkages lost, these ecdysozoans can teach us little about the origins of animals in general. The extent of this type of evolution within the superphylum will be revealed by the crustacean, annelid, and molluscan genome projects currently in progress. Analysis of the starlet sea anemone genome has emphasised the importance of sponges, placozoans, and choanoflagellates, also being sequenced, in explaining the arrival of 1500 ancestral genes unique to the Eumetazoa.
