The migration-period peoples who later coalesced into a "German" ethnicity were the Germanic tribes of the Saxons, Franci, Thuringii, Alamanni and Bavarii. These five tribes, sometimes with inclusion of the Frisians, are considered as the major groups to take part in the formation of the Germans. The varieties of the German language are still divided up into these groups. Linguists distinguish low Saxon, Franconian, Bavarian, Thuringian and Alemannic varieties in modern German. By the 9th century, the large tribes which lived on the territory of modern Germany had been united under the rule of the Frankish king Charlemagne, known in German as Karl der Groe. Much of what is now Eastern Germany became Slavonic-speaking (Sorbs and Veleti), after these areas were vacated by Germanic tribes (Vandals, Lombards, Burgundians and Suebi amongst others) which had migrated into the former areas of the Roman Empire.
What king united the tribes in the 9th century?
A: Charlemagne

The reinforcement type defines two major classes of materials - woven and non-woven. Woven reinforcements are cheaper, but the high dielectric constant of glass may not be favorable for many higher-frequency applications. The spatially nonhomogeneous structure also introduces local variations in electrical parameters, due to different resin/glass ratio at different areas of the weave pattern. Nonwoven reinforcements, or materials with low or no reinforcement, are more expensive but more suitable for some RF/analog applications.
Which is the more expensive reinforcement type?
A: non-woven

Greece is today relatively homogeneous in linguistic terms, with a large majority of the native population using Greek as their first or only language. Among the Greek-speaking population, speakers of the distinctive Pontic dialect came to Greece from Asia Minor after the Greek genocide and constitute a sizable group. The Cappadocian dialect came to Greece due to the genocide as well, but is endangered and is barely spoken now. Indigenous Greek dialects include the archaic Greek spoken by the Sarakatsani, traditionally transhument mountain shepherds of Greek Macedonia and other parts of Northern Greece. The Tsakonian language, a distinct Greek language deriving from Doric Greek instead of Ionic Greek, is still spoken in some villages in the southeastern Peloponnese.
Greeks who speak the Pontic dialect came from where?
A: Asia Minor

They invented and developed arithmetic by using several different number systems including a mixed radix system with an alternating base 10 and base 6. This sexagesimal system became the standard number system in Sumer and Babylonia. They may have invented military formations and introduced the basic divisions between infantry, cavalry, and archers. They developed the first known codified legal and administrative systems, complete with courts, jails, and government records. The first true city-states arose in Sumer, roughly contemporaneously with similar entities in what are now Syria and Lebanon. Several centuries after the invention of cuneiform, the use of writing expanded beyond debt/payment certificates and inventory lists to be applied for the first time, about 2600 BC, to messages and mail delivery, history, legend, mathematics, astronomical records, and other pursuits. Conjointly with the spread of writing, the first formal schools were established, usually under the auspices of a city-state's primary temple.
Sumerians used number systems which included what alternating bases?
A:
base 10 and base 6
