full_context: Document 1: 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 2: 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).

In the first round of the presidential elections, PAIS Alliance candidate Lenín Moreno received 39% of the vote.

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 12: Lithium: As of 2015, most of the world's lithium production is in South America, where lithium - containing brine is extracted from underground pools and concentrated by solar evaporation. The standard extraction technique is to evaporate water from brine. Each batch takes from 18 to 24 months.

Document 14: Copper: Most copper is mined or extracted as copper sulfides from large open pit mines in porphyry copper deposits that contain 0.4 to 1.0% copper. Examples include Chuquicamata in Chile, Bingham Canyon Mine in Utah, United States and El Chino Mine in New Mexico, United States. According to the British Geological Survey, in 2005, Chile was the top mine producer of copper with at least one-third world share followed by the United States, Indonesia and Peru. Copper can also be recovered through the in-situ leach process. Several sites in the state of Arizona are considered prime candidates for this method. The amount of copper in use is increasing and the quantity available is barely sufficient to allow all countries to reach developed world levels of usage.
