Input: Read this: During the First World War, to avoid ground fights between brothers, many Alsatians served as sailors in the Kaiserliche Marine and took part in the Naval mutinies that led to the abdication of the Kaiser in November 1918, which left Alsace-Lorraine without a nominal head of state. The sailors returned home and tried to found a republic. While Jacques Peirotes, at this time deputy at the Landrat Elsass-Lothringen and just elected mayor of Strasbourg, proclaimed the forfeiture of the German Empire and the advent of the French Republic, a self-proclaimed government of Alsace-Lorraine declared independence as the "Republic of Alsace-Lorraine". French troops entered Alsace less than two weeks later to quash the worker strikes and remove the newly established Soviets and revolutionaries from power. At the arrival of the French soldiers, many Alsatians and local Prussian/German administrators and bureaucrats cheered the re-establishment of order (which can be seen and is described in detail in the reference video below). Although U.S. President Woodrow Wilson had insisted that the region was self-ruling by legal status, as its constitution had stated it was bound to the sole authority of the Kaiser and not to the German state, France tolerated no plebiscite, as granted by the League of Nations to some eastern German territories at this time, because Alsatians were considered by the French public as fellow Frenchmen liberated from German rule. Germany ceded the region to France under the Treaty of Versailles.
Question: During what war were Alsatians primarily ground units?

QUES: In some jurisdictions, copyright or the right to enforce it can be contractually assigned to a third party which did not have a role in producing the work. When this outsourced litigator appears to have no intention of taking any copyright infringement cases to trial, but rather only takes them just far enough through the legal system to identify and exact settlements from suspected infringers, critics commonly refer to the party as a "copyright troll." Such practices have had mixed results in the U.S.

The distances passengers need to move within a large airport can be substantial. It is common for airports to provide moving walkways and buses. The HartsfieldJackson Atlanta International Airport has a tram that takes people through the concourses and baggage claim. Major airports with more than one terminal offer inter-terminal transportation, such as Mexico City International Airport, where the domestic building of Terminal 1 is connected by Aerotren to Terminal 2, on the other side of the airport.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How far is the distance passengers need to move between buses?
Ah, so.. unanswerable

Question: Enisa Kafadar argues that there is only one Serbo-Croatian language with several varieties. This has made possible to include all four varieties into a new grammar book. Daniel Buncic concludes that it is a pluricentric language, with four standard variants spoken in Serbia, Croatia, Montenegro and Bosnia and Herzegovina. The mutual intelligibility between their speakers "exceeds that between the standard variants of English, French, German, or Spanish". Other linguists have argued that the differences between the variants of Serbo-Croatian are less significant than those between the variants of English, German,, Dutch, and Hindi-Urdu.
