Problem: Read the following paragraph and extract the answer for the question: What practice continued on the Island until the early 20th century?  The traditions of the local peoples are unanimous in affirming that the oldest inhabitants of Casamance are the Bainuk people and that the left bank of the mouth of the river was first populated by the Jola. Portuguese sailors reached the west African coast in the 15th century, and in the 16th century, Portuguese traders became active in the Casamance region, mostly in search of wax, ivory, and slaves. They did not linger on "Mosquito Island", instead founding their first trading post at Ziguinchor in 1645.In the late 1820s, a mulatto trader from Gorée, Pierre Baudin, moved to Itou and began planting rice and producing lime by crushing the shells of mangrove oysters and cooking them in lime kilns. The French administration treated Baudin as their representative on the island and did not send others because few of the French wanted to live on the island. Being wet and marshy, Carabane had a reputation for its poor sanitation. The local economy was based mainly on weedy rice, which was sold in Ziguinchor or to the British in The Gambia. The Baudin family used slaves to produce the rice and, despite the declaration of its official abolition in the French colonial empire in 1848, slavery continued on the island until the early 20th century.The colonial administration wanted to expand its influence around the river, particularly because the inhabitants of Gorée were threatened with losing part of their resources with the imminent demise of the slave trade, and also because of their competition with Saint-Louis. On January 9, 1836, Lieutenant Malavois, who was in charge of Gorée, left for Casamance in search of a site for a trading post. The tip of Diogue, on the north shore, was first considered, but at the refusal of the Jola, it was the opposite bank which was eventually accepted.

Problem: Read the following paragraph and extract the answer for the question: What is the full name of the person Barry is an assistant for?  Teenaged brothers Zach and Gray Mitchell visit Jurassic World, a dinosaur theme park at the original Jurassic Park site on Isla Nublar. Their aunt, Claire Dearing, is the operations manager. Claire assigns her assistant, Zara, as the boys' guide but they soon evade her. Elsewhere on the island, U.S. Navy veteran and ethologist Owen Grady has been training and researching four Velociraptors. Based on the raptors' ability to follow commands, Vic Hoskins, the head of InGen Security, believes the animals can be weaponized, an idea Owen and his assistant Barry strongly oppose. Prior to its opening, Claire and park owner Simon Masrani inspect the park's newest attraction, Indominus rex, a genetically-engineered dinosaur created by geneticist Dr. Henry Wu. Masrani tasks Owen with evaluating the enclosure. Owen warns Claire the Indominus lacks social skills, making it more dangerous and unpredictable. When it appears the Indominus has escaped, Owen and two park workers enter the enclosure. The Indominus, which can camouflage itself and mask its heat signature, suddenly appears. Owen survives the attack, but it kills the other two men before escaping into the island's interior. Owen tells Masrani to have the Indominus killed; to protect his company's investment, Masrani instead dispatches a specialized unit to subdue it with non-lethal weaponry. After most of the unit is wiped out, Claire orders the evacuation of the island's northern sector.

A: Owen Grady


Problem: Read the following paragraph and extract the answer for the question: What are the first names of the four Swift family members who moved to a rented house in the suburban town of Wyomissing, Pennsylvania?  Taylor Alison Swift was born on December 13, 1989, in Reading, Pennsylvania. Her father, Scott Kingsley Swift, was a stockbroker for Merrill Lynch, and her mother, Andrea Gardner Swift (née Finlay), was a homemaker who had worked as a mutual fund marketing executive. Swift was named after the American singer-songwriter James Taylor. She has a younger brother named Austin, who is an actor. Swift spent the early years of her life on a Christmas tree farm which her father purchased from one of his clients. She attended preschool and kindergarten at the Alvernia Montessori School, run by Franciscan nuns, before transferring to The Wyndcroft School. The family then moved to a rented house in the suburban town of Wyomissing, Pennsylvania, where she attended Wyomissing Area Junior/Senior High School.At the age of nine, Swift became interested in musical theater and performed in four Berks Youth Theatre Academy productions. She also traveled regularly to New York City for vocal and acting lessons. Swift later shifted her focus toward country music inspired by Shania Twain's songs, which made her "want to just run around the block four times and daydream about everything". She spent her weekends performing at local festivals and events. After watching a documentary about Faith Hill, Swift felt sure that she needed to go to Nashville, Tennessee, to pursue a music career. At the age of eleven, she traveled with her mother to visit Nashville record labels and submitted a demo tape of Dolly Parton and Dixie Chicks karaoke covers. However, she was rejected since "everyone in that town wanted to do what I wanted to do. So, I kept thinking to myself, I need to figure out a way to be different".When Swift was about 12 years old, computer repairman and local musician Ronnie Cremer taught her how to play guitar and helped with her first efforts as a songwriter, leading to her writing "Lucky You". In 2003, Swift and her parents started working with New York-based music manager Dan Dymtrow. With his help, Swift modelled for...

Problem: Read the following paragraph and extract the answer for the question: What was the first name of the person who calculated critical mass of a sphere of uranium in a theoretical paper?  At Birmingham, Oliphant's team had reached a different conclusion. Oliphant had delegated the task to two German refugee scientists, Rudolf Peierls and Otto Frisch, who could not work on Oliphant's radar project because they were enemy aliens and therefore lacked the necessary security clearance. Francis Perrin had calculated the critical mass of uranium to be about 40 tonnes (39 long tons; 44 short tons). He reckoned that if a neutron reflector were placed around it, this might be reduced to 12 tonnes (12 long tons; 13 short tons). Peierls attempted to simplify the problem by using the fast neutrons produced by fission, thus omitting consideration of moderator. He too calculated the critical mass of a sphere of uranium in a theoretical paper written in 1939 to be "of the order of tons".Peierls knew the importance of the size of the critical mass that would allow a chain reaction to take place and its practical significance. In the interior of a critical mass sphere, neutrons are spontaneously produced by the fissionable material. A very small portion of these neutrons are colliding with other nuclei, while a larger portion of the neutrons are escaping through the surface of the sphere. Peierls calculated the equilibrium of the system, where the number of neutrons being produced equalled the number escaping.Niels Bohr had theorised that the rare uranium-235 isotope, which makes up only about 0.7% of natural uranium, was primarily responsible for fission with fast neutrons, although this was not yet universally accepted. Frisch and Peierls were thus able to revise their initial estimate of critical mass needed for nuclear fission in uranium to be substantially less than previously assumed. They estimated a metallic sphere of uranium-235 with a radius of 2.1 centimetres (0.83 in) could suffice. This amount represented approximately 1 kilogram (2.2 lb) of uranium-235. These results led to the Frisch–Peierls memorandum, which was the initial step in the development of the nuclear arms programme in Britain. This...
