Elementary and secondary public schools are overseen by the North Carolina Department of Public Instruction. The North Carolina Superintendent of Public Instruction is the secretary of the North Carolina State Board of Education, but the board, rather than the superintendent, holds most of the legal authority for making public education policy. In 2009, the board's chairman also became the "chief executive officer" for the state's school system. North Carolina has 115 public school systems, each of which is overseen by a local school board. A county may have one or more systems within it. The largest school systems in North Carolina are the Wake County Public School System, Charlotte-Mecklenburg Schools, Guilford County Schools, Winston-Salem/Forsyth County Schools, and Cumberland County Schools. In total there are 2,425 public schools in the state, including 99 charter schools. North Carolina Schools were segregated until the Brown v. Board of Education trial and the release of the Pearsall Plan.
What is the largest school system in North Carolina?
****
The answer: Wake County Public School System


The problem: Answer a question about this article:
The Appalachian Mountains (i/ˌæpəˈleɪʃᵻn/ or /ˌæpəˈlætʃᵻn/,[note 1] French: les Appalaches), often called the Appalachians, are a system of mountains in eastern North America. The Appalachians first formed roughly 480 million years ago during the Ordovician Period and once reached elevations similar to those of the Alps and the Rocky Mountains before they were eroded. The Appalachian chain is a barrier to east-west travel as it forms a series of alternating ridgelines and valleys oriented in opposition to any road running east-west.
What are the Appalachian mountains called in French?
****
The answer: les Appalaches


The problem: Answer a question about this article:
Modern geology, like modern chemistry, gradually evolved during the 18th and early 19th centuries. Benoît de Maillet and the Comte de Buffon saw the Earth as much older than the 6,000 years envisioned by biblical scholars. Jean-Étienne Guettard and Nicolas Desmarest hiked central France and recorded their observations on some of the first geological maps. Aided by chemical experimentation, naturalists such as Scotland's John Walker, Sweden's Torbern Bergman, and Germany's Abraham Werner created comprehensive classification systems for rocks and minerals—a collective achievement that transformed geology into a cutting edge field by the end of the eighteenth century. These early geologists also proposed a generalized interpretations of Earth history that led James Hutton, Georges Cuvier and Alexandre Brongniart, following in the steps of Steno, to argue that layers of rock could be dated by the fossils they contained: a principle first applied to the geology of the Paris Basin. The use of index fossils became a powerful tool for making geological maps, because it allowed geologists to correlate the rocks in one locality with those of similar age in other, distant localities. Over the first half of the 19th century, geologists such as Charles Lyell, Adam Sedgwick, and Roderick Murchison applied the new technique to rocks throughout Europe and eastern North America, setting the stage for more detailed, government-funded mapping projects in later decades.
What geological theory was applied to the Paris Basin?
****
The answer: layers of rock could be dated by the fossils they contained

The Republic of the Congo also has large untapped base metal, gold, iron and phosphate deposits. The country is a member of the Organization for the Harmonization of Business Law in Africa (OHADA). The Congolese government signed an agreement in 2009 to lease 200,000 hectares of land to South African farmers to reduce its dependence on imports.
What precious metals and minerals have yet to be utilized in the Republic of the Congo?
****
The answer:
base metal, gold, iron and phosphate
