Question: Beer was spread through Europe by Germanic and Celtic tribes as far back as 3000 BC, and it was mainly brewed on a domestic scale. The product that the early Europeans drank might not be recognised as beer by most people today. Alongside the basic starch source, the early European beers might contain fruits, honey, numerous types of plants, spices and other substances such as narcotic herbs. What they did not contain was hops, as that was a later addition, first mentioned in Europe around 822 by a Carolingian Abbot and again in 1067 by Abbess Hildegard of Bingen.
Is there an answer to this question: In 822 what did Abbess Hilegard add to beer?

Answer: unanswerable

Question: The first known smelting of iron began in Anatolia, around 1800 BC. Called the bloomery process, it produced very soft but ductile wrought iron. By 800 BC, iron-making technology had spread to Europe, arriving in Japan around 700 AD. Pig iron, a very hard but brittle alloy of iron and carbon, was being produced in China as early as 1200 BC, but did not arrive in Europe until the Middle Ages. Pig iron has a lower melting point than iron, and was used for making cast-iron. However, these metals found little practical use until the introduction of crucible steel around 300 BC. These steels were of poor quality, and the introduction of pattern welding, around the 1st century AD, sought to balance the extreme properties of the alloys by laminating them, to create a tougher metal. Around 700 AD, the Japanese began folding bloomery-steel and cast-iron in alternating layers to increase the strength of their swords, using clay fluxes to remove slag and impurities. This method of Japanese swordsmithing produced one of the purest steel-alloys of the early Middle Ages.
Is there an answer to this question: When did iron making technology begin in Japan?

Answer: around 700 AD

Question: Because of the above issues, Nigeria's political parties are pan-national and secular in character (though this does not preclude the continuing preeminence of the dominant ethnicities). The major political parties at that time included the then ruling People's Democratic Party of Nigeria, which maintains 223 seats in the House and 76 in the Senate (61.9% and 69.7% respectively); the opposition formerly All Nigeria People's Party now All Progressives Congress has 96 House seats and 27 in the Senate (26.6% and 24.7%). About twenty minor opposition parties are registered.
Is there an answer to this question: How many seats does the All Progressives Congress have in the House?

Answer: 96

Question: After August 2008 sites had to be listed on the Open Directory in order to be included. According to Jeff Kaplan of the Internet Archive in November 2010, other sites were still being archived, but more recent captures would become visible only after the next major indexing, an infrequent operation.
Is there an answer to this question: When did it become a requirement for websites to appear on Open Directory for inclusion in Kaplan?

Answer:
unanswerable
