Here is a question about this article: Around 1300–1350 the Medieval Warm Period gave way to the Little Ice Age. The colder climate resulted in agricultural crises, the first of which is known as the Great Famine of 1315-1317. The demographic consequences of this famine, however, were not as severe as the plagues that occurred later in the century, particularly the Black Death. Estimates of the death rate caused by this epidemic range from one third to as much as sixty percent. By around 1420, the accumulated effect of recurring plagues and famines had reduced the population of Europe to perhaps no more than a third of what it was a century earlier. The effects of natural disasters were exacerbated by armed conflicts; this was particularly the case in France during the Hundred Years' War.
What is the answer to this question: What was the effect of the Little Ice Age?
****
So... agricultural crises


The problem: Answer a question about this article:
Oklahoma is between the Great Plains and the Ozark Plateau in the Gulf of Mexico watershed, generally sloping from the high plains of its western boundary to the low wetlands of its southeastern boundary. Its highest and lowest points follow this trend, with its highest peak, Black Mesa, at 4,973 feet (1,516 m) above sea level, situated near its far northwest corner in the Oklahoma Panhandle. The state's lowest point is on the Little River near its far southeastern boundary near the town of Idabel, OK, which dips to 289 feet (88 m) above sea level.
What is Oklahoma's tallest mountain?
****
The answer: Black Mesa


Problem: Please answer a question about the following article about Diarrhea:
Proper nutrition is important for health and functioning, including the prevention of infectious diarrhea. It is especially important to young children who do not have a fully developed immune system. Zinc deficiency, a condition often found in children in developing countries can, even in mild cases, have a significant impact on the development and proper functioning of the human immune system. Indeed, this relationship between zinc deficiency reduced immune functioning corresponds with an increased severity of infectious diarrhea. Children who have lowered levels of zinc have a greater number of instances of diarrhea, severe diarrhea, and diarrhea associated with fever. Similarly, vitamin A deficiency can cause an increase in the severity of diarrheal episodes, however there is some discrepancy when it comes to the impact of vitamin A deficiency on the rate of disease. While some argue that a relationship does not exist between the rate of disease and vitamin A status, others suggest an increase in the rate associated with deficiency. Given that estimates suggest 127 million preschool children worldwide are vitamin A deficient, this population has the potential for increased risk of disease contraction.
What is the rate of  vitamin A deficiency in children worldwide?
A: 127 million


Question: Read this and answer the question

In 1609, English explorer Henry Hudson re-discovered the region when he sailed his ship the Halve Maen ("Half Moon" in Dutch) into New York Harbor while searching for the Northwest Passage to the Orient for his employer, the Dutch East India Company. He proceeded to sail up what he named the North River, also called the Mauritis River, and now known as the Hudson River, to the site of the present-day New York State capital of Albany in the belief that it might represent an oceanic tributary. When the river narrowed and was no longer saline, he realized it was not a maritime passage and sailed back downriver. He made a ten-day exploration of the area and claimed the region for his employer. In 1614, the area between Cape Cod and Delaware Bay would be claimed by the Netherlands and called Nieuw-Nederland (New Netherland).

In what year was the land between Cape Cod and Delaware Bay claimed by the Dutch?
Answer: 1614


Problem: Grazing organisms may also kill their prey species, but this is seldom the case. While some herbivores like zooplankton live on unicellular phytoplankton and therefore, by the individualized nature of the organism, kill their prey, many only eat a small part of the plant. Grazing livestock may pull some grass out at the roots, but most is simply grazed upon, allowing the plant to regrow once again. Kelp is frequently grazed in subtidal kelp forests, but regrows at the base of the blade continuously to cope with browsing pressure. Animals may also be 'grazed' upon; female mosquitos land on hosts briefly to gain sufficient proteins for the development of their offspring. Starfish may be grazed on, being capable of regenerating lost arms.
Do grazing organisms often kill their prey?
The answer is the following: seldom


Input: Article: General Aguirre moved to the deserts of the southeastern portion of the state and defeated the French forces in Parral, led by Colonel Cottret. By the middle of 1866, the state of Chihuahua was declared free of enemy control; Parral was the last French stronghold within the state. On June 17, 1866, President Juárez arrived in Chihuahua City and remained in the capital until December 10, 1866. During his two years in the state of Chihuahua, President Juárez passed ordinances regarding the rights of adjudication of property and nationalized the property of the clergy. The distance of the French forces and their allies allowed the Ministry of War, led by General Negrete, to reorganize the state's national guard into the Patriotic Battalion of Chihuahua, which was deployed to fight in the battle of Matamoros, Tamaulipas against the French. After a series of major defeats and an escalating threat from Prussia, France began pulling troops out of Mexico in late 1866. Disillusioned with the liberal political views of Maximilian, the Mexican conservatives abandoned him, and in 1867 the last of the Emperor's forces were defeated. Maximilian was sentenced to death by a military court; despite national and international pleas for amnesty, Juárez refused to commute the sentence. Maximilian was executed by firing squad on June 19, 1867.

Now answer this question: During which year was Chihuahua declared free of enemy control?

Output:
1866
