Ecuador was the site of many indigenous cultures, and civilizations of different proportions. An early sedentary culture, known as the Valdivia culture, developed in the coastal region, while the Caras and the Quitus unified to form an elaborate civilization that ended at the birth of the Capital Quito.

Their architecture remains were later destroyed by Spaniards and the Incas.

Input: Middle Ages
Medieval writers divided history into periods such as the "Six Ages" or the "Four Empires", and considered their time to be the last before the end of the world. When referring to their own times, they spoke of them as being "modern". In the 1330s, the humanist and poet Petrarch referred to pre-Christian times as antiqua (or "ancient") and to the Christian period as nova (or "new"). Leonardo Bruni was the first historian to use tripartite periodisation in his History of the Florentine People (1442). Bruni and later historians argued that Italy had recovered since Petrarch's time, and therefore added a third period to Petrarch's two. The "Middle Ages" first appears in Latin in 1469 as media tempestas or "middle season". In early usage, there were many variants, including medium aevum, or "middle age", first recorded in 1604, and media saecula, or "middle ages", first recorded in 1625. The alternative term "medieval" (or occasionally "mediaeval") derives from medium aevum. Tripartite periodisation became standard after the German 17th century historian Christoph Cellarius divided history into three periods: Ancient, Medieval, and Modern.

Who first divided history into the ancient, medieval and modern periods?
Output: Christoph Cellarius

Input: Child labour
In Brazil, the minimum working age has been identified as fourteen due to continuous constitutional amendments that occurred in 1934, 1937, and 1946. Yet due to a change in the dictatorship by the military in the 80's, the minimum age restriction was reduced to the age of twelve but was reviewed due to reports of dangerous and hazardous working conditions in 1988. This led to the minimum age being raised once again to 14. Another set of restrictions was passed in 1998 that restricted the kinds of work youth could partake in, such as work that was considered hazardous like running construction equipment, or certain kinds of factory work. Although many steps were taken to reduce the risk and occurrence of child labour, there is still a high number of children and adolescents working under the age of fourteen in Brazil. It was not until recently in the 80's that it was discovered that almost nine million children in Brazil were working illegally and not partaking in traditional childhood activities that help to develop important life experiences.

In the 80's how many children were working illegally in Brazil?
Output:
almost nine million
