Problem: Thuringia:

During the Middle Ages, Thuringia was situated at the border between Germanic and Slavic territories, marked by the Saale river. The Ostsiedlung movement led to the assimilation of Slavic people between the 11th and the 13th century under German rule. The population growth increased during the 18th century and stayed high until World War I, before it slowed within the 20th century and changed to a decline since 1990. Since the beginning of Urbanisation around 1840, the Thuringian cities have higher growth rates resp. smaller rates of decline than rural areas (many villages lost half of their population since 1950, whereas the biggest cities (Erfurt and Jena) keep growing).

Where was Thuringia in the Middle Ages?

A: the border between Germanic and Slavic territories

Problem: The philosophies of Buddhism and Zen, and to a lesser extent Confucianism and Shinto, influenced the samurai culture. Zen meditation became an important teaching due to it offering a process to calm one's mind. The Buddhist concept of reincarnation and rebirth led samurai to abandon torture and needless killing, while some samurai even gave up violence altogether and became Buddhist monks after realizing how fruitless their killings were. Some were killed as they came to terms with these realizations in the battlefield. The most defining role that Confucianism played in samurai philosophy was to stress the importance of the lord-retainer relationshipthe loyalty that a samurai was required to show his lord.
What was the contribution of Confucianism to samurai?

Answer: to stress the importance of the lord-retainer relationship

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Bohemia (as Czech civilization was known by then) increased in power over the centuries, as its language did in regional importance. This growth was expedited during the fourteenth century by Holy Roman Emperor Charles IV, who founded Charles University in Prague in 1348. Here, early Czech literature (a biblical translation, hymns and hagiography) flourished. Old Czech texts, including poetry and cookbooks, were produced outside the university as well. Later in the century Jan Hus contributed significantly to the standardization of Czech orthography, advocated for widespread literacy among Czech commoners (particularly in religion) and made early efforts to model written Czech after the spoken language.
In what city did Jan Hus found Charles University?
A: unanswerable

Context and question: In 1582 the United Provinces invited Francis, Duke of Anjou to lead them; but after a failed attempt to take Antwerp in 1583, the duke left the Netherlands again. After the assassination of William of Orange (10 July 1584), both Henry III of France and Elizabeth I of England declined the offer of sovereignty. However, the latter agreed to turn the United Provinces into a protectorate of England (Treaty of Nonsuch, 1585), and sent the Earl of Leicester as governor-general. This was unsuccessful and in 1588 the provinces became a confederacy. The Union of Utrecht is regarded as the foundation of the Republic of the Seven United Provinces, which was not recognized by the Spanish Empire until the Peace of Westphalia in 1648.
What did Henry III do with the United Provinces after William of Orange was assassinated?
Answer: unanswerable

Question: Dietary fiber is a carbohydrate that is incompletely absorbed in humans and in some animals. Like all carbohydrates, when it is metabolized it can produce four Calories (kilocalories) of energy per gram. However, in most circumstances it accounts for less than that because of its limited absorption and digestibility. Dietary fiber consists mainly of cellulose, a large carbohydrate polymer which is indigestible as humans do not have the required enzymes to disassemble it. There are two subcategories: soluble and insoluble fiber. Whole grains, fruits (especially plums, prunes, and figs), and vegetables are good sources of dietary fiber. There are many health benefits of a high-fiber diet. Dietary fiber helps reduce the chance of gastrointestinal problems such as constipation and diarrhea by increasing the weight and size of stool and softening it. Insoluble fiber, found in whole wheat flour, nuts and vegetables, especially stimulates peristalsis the rhythmic muscular contractions of the intestines, which move digesta along the digestive tract. Soluble fiber, found in oats, peas, beans, and many fruits, dissolves in water in the intestinal tract to produce a gel that slows the movement of food through the intestines. This may help lower blood glucose levels because it can slow the absorption of sugar. Additionally, fiber, perhaps especially that from whole grains, is thought to possibly help lessen insulin spikes, and therefore reduce the risk of type 2 diabetes. The link between increased fiber consumption and a decreased risk of colorectal cancer is still uncertain.
Is there an answer to this question: How many kilocalories of energy per gram is dietary fiber able to produce when successfully metabolized?

Answer: four

Many minerals provide pigments which have been used in green paints and dyes over the centuries. Pigments, in this case, are minerals which reflect the color green, rather that emitting it through luminescent or phosphorescent qualities. The large number of green pigments makes it impossible to mention them all. Among the more notable green minerals, however is the emerald, which is colored green by trace amounts of chromium and sometimes vanadium. Chromium(III) oxide (Cr2O3), is called chrome green, also called viridian or institutional green when used as a pigment. For many years, the source of amazonite's color was a mystery. Widely thought to have been due to copper because copper compounds often have blue and green colors, the blue-green color is likely to be derived from small quantities of lead and water in the feldspar. Copper is the source of the green color in malachite pigments, chemically known as basic copper(II) carbonate.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What is the symbol for Copper?
Ah, so..
