Education is the process of facilitating learning, or the acquisition of knowledge, skills, values, beliefs, and habits. Educational methods include teaching, training, storytelling, discussion and directed research. Education frequently takes place under the guidance of educators, however learners can also educate themselves. Education can take place in formal or informal settings and any experience that has a formative effect on the way one thinks, feels, or acts may be considered educational. The methodology of teaching is called pedagogy.

Secondary education covers two phases on the International Standard Classification of Education scale. Level 2 or lower secondary education is considered the second and final phase of basic education, and level 3 (upper) secondary education is the stage before tertiary education. Every country aims to provide basic education, but the systems and terminology remain unique to them. Secondary education typically takes place after six years of primary education and is followed by higher education, vocational education or employment. Like primary education, in most countries secondary education is compulsory, at least until the age of 16. Children typically enter the lower secondary phase around age 11. Compulsory education sometimes extends to age 19.
Testosterone is the primary male sex hormone and an anabolic steroid. In male humans, testosterone plays a key role in the development of male reproductive tissues such as testes and prostate, as well as promoting secondary sexual characteristics such as increased muscle and bone mass, and the growth of body hair. In addition, testosterone is involved in health and well-being, and the prevention of osteoporosis. Insufficient levels of testosterone in men may lead to abnormalities including frailty and bone loss.
A top-level domain (TLD) is one of the domains at the highest level in the hierarchical Domain Name System of the Internet. The top-level domain names are installed in the root zone of the name space. For all domains in lower levels, it is the last part of the domain name, that is, the last label of a fully qualified domain name. For example, in the domain name www.example.com, the top-level domain is com. Responsibility for management of most top-level domains is delegated to specific organizations by the Internet Corporation for Assigned Names and Numbers (ICANN), which operates the Internet Assigned Numbers Authority (IANA), and is in charge of maintaining the DNS root zone.
The Dow Jones Industrial Average (DJIA), or simply the Dow, is a stock market index that measures the stock performance of 30 large companies listed on stock exchanges in the United States. Although it is one of the most commonly followed equity indices, since it only includes 30 companies and is not weighted by market capitalization and is not a weighted arithmetic mean, many consider the Dow to not be a good representation of the U.S. stock market and consider the S&P 500 Index, which also includes the 30 components of the Dow, to be a better representation of the U.S. stock market.
In the United Kingdom, the General Certificate of Secondary Education (GCSE) is an academic qualification, generally taken in a number of subjects by pupils in secondary education in England, Wales, and Northern Ireland. State education in Scotland does not use GCSEs; instead its Scottish Qualifications Certificate operates National/Intermediate exams at the equivalent level. However, certain private schools in Scotland offer GCSEs, and the proportion of Scottish pupils taking GCSEs to facilitate admission to English universities is increasing.

Under the Nigerian Constitution, states have the power to ratify constitutional amendments.
The English football league system, also known as the football pyramid, is a series of interconnected leagues for men's association football clubs in England, with five teams from Wales, one from Guernsey and one from Jersey also competing. The system has a hierarchical format with promotion and relegation between leagues at different levels, allowing even the smallest club the theoretical possibility of ultimately rising to the very top of the system. There are more than 140 individual leagues, containing more than 480 divisions.
Ninth grade, freshman year, or grade 9 is the ninth post-kindergarten year of school education in some school systems. Ninth grade is often the first school year of high school in the United States, or the last year of middle/junior high school. In some countries Grade 9 is the second year of high school. Students are usually 14–15 years old. In the United States, it is often called Freshman year. In England and Wales, the equivalent educational year is Year Ten. In Scotland the equivalent educational year is Third Year or S3, as this is the third year of compulsory secondary schooling.
An apex predator, also known as an alpha predator or top predator, is a predator at the top of a food chain, with no natural predators.
The French football league system is a series of interconnected leagues for club football in France and Monaco, and includes one Spanish side. At the top two levels of the system is the Ligue de Football Professionnel, which consists of two professional national divisions, Ligue 1 and Ligue 2. Below that are a number of leagues run by the Fédération Française de Football. At level 3 is the semi-professional Championnat National. Below that is the amateur Championnat National 2, which is divided into four parallel regional divisions, followed by the Championnat National 3, which is divided into 12 parallel regional divisions. Underneath that are many more regional and departmental leagues and divisions. Clubs finishing the season at or near the top of their division may be eligible for promotion to a higher division. Similarly, clubs finishing at or near the bottom of their division may be relegated to a lower division.
Global warming is the long-term rise in the average temperature of the Earth's climate system. It is a major aspect of climate change, and has been demonstrated by direct temperature measurements and by measurements of various effects of the warming. Global warming and climate change are often used interchangeably. But more accurately, global warming is the mainly human-caused increase in global surface temperatures and its projected continuation, while climate change includes both global warming and its effects, such as changes in precipitation. While there have been prehistoric periods of global warming, many observed changes since the mid-20th century have been unprecedented over decades to millennia.

Since at least the start of the 20th century, the average global sea level has been rising. Between 1900 and 2016, the sea level rose by 16–21 cm (6.3–8.3 in). More precise data gathered from satellite radar measurements reveal an accelerating rise of 7.5 cm (3.0 in) from 1993 to 2017, which is a trend of roughly 30 cm (12 in) per century. This acceleration is due mostly to human-caused global warming, which is driving thermal expansion of seawater and the melting of land-based ice sheets and glaciers. Between 1993 and 2018, thermal expansion of the oceans contributed 42% to sea level rise; the melting of temperate glaciers, 21%; Greenland, 15%; and Antarctica, 8%. Climate scientists expect the rate to further accelerate during the 21st century.
