Problem: Polabian Slavs (Wends) settled in parts of England (Danelaw), apparently as Danish allies. Polabian-Pomeranian Slavs are also known to have even settled on Norse age Iceland. Saqaliba refers to the Slavic mercenaries and slaves in the medieval Arab world in North Africa, Sicily and Al-Andalus. Saqaliba served as caliph's guards. In the 12th century, there was intensification of Slavic piracy in the Baltics. The Wendish Crusade was started against the Polabian Slavs in 1147, as a part of the Northern Crusades. Niklot, pagan chief of the Slavic Obodrites, began his open resistance when Lothar III, Holy Roman Emperor, invaded Slavic lands. In August 1160 Niklot was killed and German colonization (Ostsiedlung) of the Elbe-Oder region began. In Hanoverian Wendland, Mecklenburg-Vorpommern and Lusatia invaders started germanization. Early forms of germanization were described by German monks: Helmold in the manuscript Chronicon Slavorum and Adam of Bremen in Gesta Hammaburgensis ecclesiae pontificum. The Polabian language survived until the beginning of the 19th century in what is now the German state of Lower Saxony. In Eastern Germany, around 20% of Germans have Slavic paternal ancestry. Similarly, in Germany, around 20% of the foreign surnames are of Slavic origin.

Answer: Norse age Iceland


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
In presidential elections, Montana was long classified as a swing state, though the state has voted for the Republican candidate in all but two elections from 1952 to the present. The state last supported a Democrat for president in 1992, when Bill Clinton won a plurality victory. Overall, since 1889 the state has voted for Democratic governors 60 percent of the time and Democratic presidents 40 percent of the time, with these numbers being 40/60 for Republican candidates. In the 2008 presidential election, Montana was considered a swing state and was ultimately won by Republican John McCain, albeit by a narrow margin of two percent.

A: 60 percent


Context and question: The early currency of the United States did not exhibit faces of presidents, as is the custom now; although today, by law, only the portrait of a deceased individual may appear on United States currency. In fact, the newly formed government was against having portraits of leaders on the currency, a practice compared to the policies of European monarchs. The currency as we know it today did not get the faces they currently have until after the early 20th century; before that "heads" side of coinage used profile faces and striding, seated, and standing figures from Greek and Roman mythology and composite Native Americans. The last coins to be converted to profiles of historic Americans were the dime (1946) and the Dollar (1971).
When did modern day currency start getting the faces that they have?
Answer: 20th century


Question: As of 2009, Internet via satellite had a steady growth rate of 10% to 15% per year. It was particularly in demand in remote areas that did not have either dialup or wireless online services. The local telecommunications company Dalkom Somalia provided internet over satellite, as well as premium routes for media operators and content providers, and international voice gateway services for global carriers. It also offered inexpensive bandwidth through its internet backbone, whereas bandwidth ordinarily cost customers from $2,500 to $3,000 per month through the major international bandwidth providers. The main clients of these local satellite services were internet cafes, money transfer firms and other companies, as well as international community representatives. In total, there were over 300 local satellite terminals available aross the nation, which were linked to teleports in Europe and Asia. Demand for the satellite services gradually began to fall as broadband wireless access rose. However, it increased in rural areas, as the main client base for the satellite services extended their operations into more remote locales.
Is there an answer to this question: Dalkom Somalia provided internet over what?

Answer: satellite
