input question: Question: "What happened in the 13th year of the century known as the 2000's?" Context: "Nigeria was the only country in Africa to have never eradicated polio, which it periodically exported to other African countries; Polio was cut 98% between 2009 and 2010. However, a major breakthrough came in December 2014, when it was reported that Nigeria hadn't recorded a polio case in 6 months, and on its way to be declared Polio free. In 2012, a new bone marrow donor program was launched by the University of Nigeria to help people with leukaemia, lymphoma, or sickle cell disease to find a compatible donor for a life-saving bone marrow transplant, which cures them of their conditions. Nigeria became the second African country to have successfully carried out this surgery. In the 2014 ebola outbreak, Nigeria was the first country to effectively contain and eliminate the Ebola threat that was ravaging three other countries in the West African region, the Nigerian unique method of contact tracing employed by Nigeria became an effective method later used by countries, such as the united States, when ebola threats were discovered." Answer:???
output answer: a new bone marrow donor program was launched by the University of Nigeria

input question: Question: "Which school of architecture became popular first, modern or neoclassical?" Context: "After a lull during the period of modern architectural dominance (roughly post-World War II until the mid-1980s), neoclassicism has seen somewhat of a resurgence. This rebirth can be traced to the movement of New Urbanism and postmodern architecture's embrace of classical elements as ironic, especially in light of the dominance of Modernism. While some continued to work with classicism as ironic, some architects such as Thomas Gordon Smith, began to consider classicism seriously. While some schools had interest in classical architecture, such as the University of Virginia, no school was purely dedicated to classical architecture. In the early 1990s a program in classical architecture was started by Smith and Duncan Stroik at the University of Notre Dame that continues successfully. Programs at the University of Miami, Andrews University, Judson University and The Prince's Foundation for Building Community have trained a number of new classical architects since this resurgence. Today one can find numerous buildings embracing neoclassical style, since a generation of architects trained in this discipline shapes urban planning." Answer:???
output answer: neoclassical
