full_context: Document 1: Poinsettia: The poinsettia (/ pɔɪnˈsɛtiə / or / pɔɪnˈsɛtə /) (Euphorbia pulcherrima) is a commercially important plant species of the diverse spurge family (Euphorbiaceae). The species is indigenous to Mexico. It is particularly well known for its red and green foliage and is widely used in Christmas floral displays. It derives its common English name from Joel Roberts Poinsett, the first United States Minister to Mexico, who introduced the plant to the US in 1825.
Document 2: Botany: Botany originated in prehistory as herbalism with the efforts of early humans to identify – and later cultivate – edible, medicinal and poisonous plants, making it one of the oldest branches of science. Medieval physic gardens, often attached to monasteries, contained plants of medical importance. They were forerunners of the first botanical gardens attached to universities, founded from the 1540s onwards. One of the earliest was the Padua botanical garden. These gardens facilitated the academic study of plants. Efforts to catalogue and describe their collections were the beginnings of plant taxonomy, and led in 1753 to the binomial system of Carl Linnaeus that remains in use to this day.
Document 3: New York City: Approximately 37% of the city's population is foreign born. In New York, no single country or region of origin dominates. The ten largest sources of foreign-born individuals in the city as of 2011 were the Dominican Republic, China, Mexico, Guyana, Jamaica, Ecuador, Haiti, India, Russia, and Trinidad and Tobago, while the Bangladeshi immigrant population has since become one of the fastest growing in the city, counting over 74,000 by 2013.
Document 4: Dominican Republic: The Dominican Republic is a representative democracy or democratic republic, with three branches of power: executive, legislative, and judicial. The president of the Dominican Republic heads the executive branch and executes laws passed by the congress, appoints the cabinet, and is commander in chief of the armed forces. The president and vice-president run for office on the same ticket and are elected by direct vote for 4-year terms. The national legislature is bicameral, composed of a senate, which has 32 members, and the Chamber of Deputies, with 178 members.Judicial authority rests with the Supreme Court of Justice's 16 members. They are appointed by a council composed of the president, the leaders of both houses of Congress, the President of the Supreme Court, and an opposition or non–governing-party member. The court "alone hears actions against the president, designated members of his Cabinet, and members of Congress when the legislature is in session."The Dominican Republic has a multi-party political system. Elections are held every two years, alternating between the presidential elections, which are held in years evenly divisible by four, and the congressional and municipal elections, which are held in even-numbered years not divisible by four. "International observers have found that presidential and congressional elections since 1996 have been generally free and fair." The Central Elections Board (JCE) of nine members supervises elections, and its decisions are unappealable. Starting from 2016, elections will be held jointly, after a constitutional reform.
Document 5: Haiti: The island was named La Española and claimed by Spain, which ruled until the early 17th century.

Document 6: 2017 Ecuadorian general election: General elections were held in Ecuador on 19 February 2017 alongside a referendum on tax havens. Voters elected a new President and National Assembly. Incumbent President Rafael Correa of the PAIS Alliance was not eligible for re-election, having served two terms. In the first round of the presidential elections, PAIS Alliance candidate Lenín Moreno received 39% of the vote. Although he was more than 10% ahead of his nearest rival, Guillermo Lasso of the Creating Opportunities party, Moreno was just short of the 40% threshold required to avoid a run - off. As a result, a second round was held on 2 April. In the second round Moreno was elected President with 51.16% of the vote.
Document 7: Paraguay: Paraguay is a representative democratic republic, with a multi-party system and separation of powers in three branches. Executive power is exercised solely by the President, who is head of state and head of government. Legislative power is vested in the two chambers of the National Congress. The judiciary is vested on tribunals and Courts of Civil Law and a nine-member Supreme Court of Justice, all of them independent of the executive and the legislature.
Document 8: Kenya: Kenya is a presidential representative democratic republic. The president is both the head of state and head of government, and of a multi-party system. Executive power is exercised by the government. Legislative power is vested in both the government and the National Assembly and the Senate. The Judiciary is independent of the executive and the legislature. There was growing concern especially during former president Daniel arap Moi's tenure that the executive was increasingly meddling with the affairs of the judiciary.Kenya has a high degree of corruption according to Transparency International's Corruption Perception Index (CPI), a metric which attempts to gauge the prevalence of public sector corruption in various countries. In 2012, the nation placed 139th out of 176 total countries in the CPI, with a score of 27/100. However, there are several rather significant developments with regards to curbing corruption from the Kenyan government, for instance, the establishment of a new and independent Ethics and Anti-Corruption Commission (EACC).

Subsequent acts of the National Assembly are supreme over Executive Orders where sufficient votes have been cast by the legislators. The judiciary is independent of the executive and the legislature. There is also constitutional republic
Document 10: Mexico City: On the other hand, Mexico City is also home to large communities of expatriates and immigrants, most notably from the rest of North America (U.S. and Canada), from South America (mainly from Argentina and Colombia, but also from Brazil, Chile, Uruguay and Venezuela), from Central America and the Caribbean (mainly from Cuba, Guatemala, El Salvador, Haiti and Honduras); from Europe (mainly from Spain, Germany and Switzerland, but also from Czech Republic, Hungary, France, Italy, Ireland, the Netherlands, Poland and Romania), from the Middle East (mainly from Egypt, Lebanon and Syria); and recently from Asia-Pacific (mainly from China and South Korea). Historically since the era of New Spain, many Filipinos settled in the city and have become integrated in Mexican society. While no official figures have been reported, population estimates of each of these communities are quite significant.

Document 12: Stevia: The plant Stevia rebaudiana has been used for more than 1,500 years by the Guaraní peoples of South America, who called it ka'a he'ê (``sweet herb ''). The leaves have been used traditionally for hundreds of years in both Brazil and Paraguay to sweeten local teas and medicines, and as a`` sweet treat''. The genus was named for Spanish botanist and physician Petrus Jacobus Stevus (Pedro Jaime Esteve 1500 -- 1556), a professor of botany at the University of Valencia.

Document 14: New York City: The wider New York City metropolitan area, with over 20 million people, about 50% greater than the second-place Los Angeles metropolitan area in the United States, is also ethnically diverse. The New York region continues to be by far the leading metropolitan gateway for legal immigrants admitted into the United States, substantially exceeding the combined totals of Los Angeles and Miami, the next most popular gateway regions. It is home to the largest Jewish as well as Israeli communities outside Israel, with the Jewish population in the region numbering over 1.5 million in 2012 and including many diverse Jewish sects from around the Middle East and Eastern Europe. The metropolitan area is also home to 20% of the nation's Indian Americans and at least 20 Little India enclaves, as well as 15% of all Korean Americans and four Koreatowns; the largest Asian Indian population in the Western Hemisphere; the largest Russian American, Italian American, and African American populations; the largest Dominican American, Puerto Rican American, and South American and second-largest overall Hispanic population in the United States, numbering 4.8 million; and includes at least 6 established Chinatowns within New York City alone, with the urban agglomeration comprising a population of 779,269 overseas Chinese as of 2013 Census estimates, the largest outside of Asia.
