Here is a question about this article: The High Middle Ages was the formative period in the history of the modern Western state. Kings in France, England, and Spain consolidated their power, and set up lasting governing institutions. New kingdoms such as Hungary and Poland, after their conversion to Christianity, became Central European powers. The Magyars settled Hungary around 900 under King Arpad (d. c. 907) after a series of invasions in the 9th century. The papacy, long attached to an ideology of independence from secular kings, first asserted its claim to temporal authority over the entire Christian world; the Papal Monarchy reached its apogee in the early 13th century under the pontificate of Innocent III (pope 11981216). Northern Crusades and the advance of Christian kingdoms and military orders into previously pagan regions in the Baltic and Finnic north-east brought the forced assimilation of numerous native peoples into European culture.
What is the answer to this question: Along with Poland, what Central European kingdom was formed during the High Middle Ages?
****
So... Hungary

Here is a question about this article: Given that water contamination is a major means of transmitting diarrheal disease, efforts to provide clean water supply and improved sanitation have the potential to dramatically cut the rate of disease incidence. In fact, it has been proposed that we might expect an 88% reduction in child mortality resulting from diarrheal disease as a result of improved water sanitation and hygiene. Similarly, a meta-analysis of numerous studies on improving water supply and sanitation shows a 2227% reduction in disease incidence, and a 2130% reduction in mortality rate associated with diarrheal disease.
What is the answer to this question: What would be the reduction in deisease incedence if there was better water and sanitation?
****
So... 2227% reduction in disease incidence

Here is a question about this article: Education in Switzerland is very diverse because the constitution of Switzerland delegates the authority for the school system to the cantons. There are both public and private schools, including many private international schools. The minimum age for primary school is about six years in all cantons, but most cantons provide a free "children's school" starting at four or five years old. Primary school continues until grade four, five or six, depending on the school. Traditionally, the first foreign language in school was always one of the other national languages, although recently (2000) English was introduced first in a few cantons.
What is the answer to this question: Who has authority of school systems in Switzerland?
****
So...
the cantons
