During the tumultuous 14th century, disputes within the leadership of the Church led to the Avignon Papacy of 130578, also called the "Babylonian Captivity of the Papacy" (a reference to the Babylonian captivity of the Jews), and then to the Great Schism, lasting from 1378 to 1418, when there were two and later three rival popes, each supported by several states. Ecclesiastical officials convened at the Council of Constance in 1414, and in the following year the council deposed one of the rival popes, leaving only two claimants. Further depositions followed, and in November 1417 the council elected Martin V (pope 141731) as pope.
When did the Great Schism end?
****
The answer: 1418

The word "paper" is etymologically derived from Latin papyrus, which comes from the Greek (papuros), the word for the Cyperus papyrus plant. Papyrus is a thick, paper-like material produced from the pith of the Cyperus papyrus plant, which was used in ancient Egypt and other Mediterranean cultures for writing before the introduction of paper into the Middle East and Europe. Although the word paper is etymologically derived from papyrus, the two are produced very differently and the development of the first is distinct from the development of the second. Papyrus is a lamination of natural plant fibres, while paper is manufactured from fibres whose properties have been changed by maceration.
What part of the Cyperus plant was used in making papyrus?
****
The answer: the pith

The problem: Answer a question about this article:
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.
What is the min working age in Brazil?
****
The answer: fourteen

The problem: Answer a question about this article:
The development of a three-field rotation system for planting crops[AA] increased the usage of land from one half in use each year under the old two-field system to two-thirds under the new system, with a consequent increase in production. The development of the heavy plough allowed heavier soils to be farmed more efficiently, aided by the spread of the horse collar, which led to the use of draught horses in place of oxen. Horses are faster than oxen and require less pasture, factors that aided the implementation of the three-field system.
What invention allowed horses rather than oxen to be used to plow?
****
The answer:
the horse collar
