Question: What is the age limit for NYSC in the country that Ferronigerite-2N1S is named after?

full_context: Document 1: Ferronigerite-2N1S: Ferronigerite-2N1S was first discovered in the Kabba provence of central Nigeria in 1944; it was originally named Nigerite. Its name was later changed to nigerite-6H then to nigerite-6T and in 2003 ferronigertie-2N1S was approved by the International Mineralogical Association.
Document 2: Nigeria: The Niger Delta Nembe Creek Oil field was discovered in 1973 and produces from middle Miocene deltaic sandstone-shale in an anticline structural trap at a depth of 2–4 km. In June 2013, the company announced a strategic review of its operations in Nigeria, hinting that assets could be divested. While many international oil companies have operated there for decades, by 2014 most were making moves to divest their interests, citing a range of issues including oil theft. In August 2014, Shell Oil Company said it was finalising its interests in four Nigerian oil fields.
Document 3: Niobium: Columbium (symbol "Cb") was the name originally bestowed by Hatchett upon his discovery of the metal in 1801. The name reflected that the type specimen of the ore came from America (Columbia). This name remained in use in American journals—the last paper published by American Chemical Society with columbium in its title dates from 1953—while niobium was used in Europe. To end this confusion, the name niobium was chosen for element 41 at the 15th Conference of the Union of Chemistry in Amsterdam in 1949. A year later this name was officially adopted by the International Union of Pure and Applied Chemistry (IUPAC) after 100 years of controversy, despite the chronological precedence of the name columbium.  This was a compromise of sorts; the IUPAC accepted tungsten instead of wolfram in deference to North American usage; and niobium instead of columbium in deference to European usage. While many US chemical societies and government organizations typically use the official IUPAC name, some metallurgists and metal societies still use the original American name, "columbium".

Document 5: Saint Helena: The Education and Employment Directorate also offers programmes for students with special needs, vocational training, adult education, evening classes, and distance learning. The island has a public library (the oldest in the Southern Hemisphere) and a mobile library service which operates weekly rural areas.
Document 6: Brigham Young University: Some 97 percent of male BYU graduates and 32 percent of female graduates took a hiatus from their undergraduate studies at one point to serve as LDS missionaries. In October 2012, the LDS Church announced at its general conference that young men could serve a mission after they turn 18 and have graduated from high school, rather than after age 19 under the old policy. Many young men would often attend a semester or two of higher education prior to beginning missionary service. This policy change will likely impact what has been the traditional incoming freshman class at BYU. Female students may now begin their missionary service anytime after turning 19, rather than age 21 under the previous policy. For males, a full-time mission is two years in length, and for females it lasts 18 months.
Document 7: Sial: The name 'sial' was taken from the first two letters of silica and of alumina. The sial is often contrasted to the 'sima,' the next lower layer in the Earth, which is often exposed in the ocean basins; and the nickel - iron alloy core, sometimes referred to as the ``Nife ''. These geochemical divisions of the Earth's interior (with these names) were first proposed by Eduard Suess in the 19th century. This model of the outer layers of the earth has been confirmed by petrographic, gravimetric, and seismic evidence.
Document 8: Nigeria: The name "" was taken from the Niger River running through the country. This name was coined in the late 19th century by British journalist Flora Shaw, who later married Lord Lugard, a British colonial administrator. The origin of the name "Niger", which originally applied only to the middle reaches of the Niger River, is uncertain. The word is likely an alteration of the Tuareg name "egerew n-igerewen" used by inhabitants along the middle reaches of the river around Timbuktu prior to 19th-century European colonialism.

Students who complete a certain level of secondary education (``high school '') may take a standardized test and be graduated from compulsory education, the General Equivalency Degree. Gifted and talented students are also generally permitted by several states to accelerate their education so as to obtain a diploma prior to attaining the leaving age. Young people may seek employment at 14 in many states but, in practice, most employers seek someone slightly older. However, it is common for those aged 14 (and even younger) to gain employment in agriculture. * Varies by State or Territory
Document 10: National Youth Service Corps: Nigerian Graduates are ineligible for employment in governmental establishments (and few private establishments) till they have completed the mandatory one year service. Graduates who are exempted from the service include those above the age of thirty (30) and those with physical disability, therefore completing the service year entitles one to employment. During the service year, Corps members have the opportunity of learning of the cultures of other people, an opportunity many Nigerians never get in their lifetime. The program has also helped in creating entry - level jobs for many Nigerian youth. An NYSC forum dedicated to the NYSC members was built to bridge the gap amongst members serving across Nigeria and also an avenue for corpers to share job information and career resources as well as getting loans from the National Directorate Of Employment.

Working parents can also receive from their employers childcare worth £55 per week free of income tax, which is typically enough to pay for one or two days per week.

The program is often seen as a domestic Peace Corps. It employs more than 75,000 Americans in intensive service each year.
