Problem: Identity (social science):

Boundaries can be inclusive or exclusive depending on how they are perceived by other people. An exclusive boundary arises, for example, when a person adopts a marker that imposes restrictions on the behaviour of others. An inclusive boundary is created, by contrast, by the use of a marker with which other people are ready and able to associate. At the same time, however, an inclusive boundary will also impose restrictions on the people it has included by limiting their inclusion within other boundaries. An example of this is the use of a particular language by a newcomer in a room full of people speaking various languages. Some people may understand the language used by this person while others may not. Those who do not understand it might take the newcomer's use of this particular language merely as a neutral sign of identity. But they might also perceive it as imposing an exclusive boundary that is meant to mark them off from her. On the other hand, those who do understand the newcomer's language could take it as an inclusive boundary, through which the newcomer associates herself with them to the exclusion of the other people present. Equally, however, it is possible that people who do understand the newcomer but who also speak another language may not want to speak the newcomer's language and so see her marker as an imposition and a negative boundary. It is possible that the newcomer is either aware or unaware of this, depending on whether she herself knows other languages or is conscious of the plurilingual quality of the people there and is respectful of it or not.

What boundary is given as an example that can be inclusive or exclusive?

A: language

Problem: After Christianization, the Roman Catholic Church and local rulers led German expansion and settlement in areas inhabited by Slavs and Balts, known as Ostsiedlung. During the wars waged in the Baltic by the Catholic German Teutonic Knights; the lands inhabited by the ethnic group of the Old Prussians (the current reference to the people known then simply as the "Prussians"), were conquered by the Germans. The Old Prussians were an ethnic group related to the Latvian and Lithuanian Baltic peoples. The former German state of Prussia took its name from the Baltic Prussians, although it was led by Germans who had assimilated the Old Prussians; the old Prussian language was extinct by the 17th or early 18th century. The Slavic people of the Teutonic-controlled Baltic were assimilated into German culture and eventually there were many intermarriages of Slavic and German families, including amongst the Prussia's aristocracy known as the Junkers. Prussian military strategist Karl von Clausewitz is a famous German whose surname is of Slavic origin. Massive German settlement led to the assimilation of Baltic (Old Prussians) and Slavic (Wends) populations, who were exhausted by previous warfare.
Who held back the German expansion?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
In the 1990s, Dell switched from using primarily ATX motherboards and PSU to using boards and power supplies with mechanically identical but differently wired connectors. This meant customers wishing to upgrade their hardware would have to replace parts with scarce Dell-compatible parts instead of commonly available parts. While motherboard power connections reverted to the industry standard in 2003, Dell continues to remain secretive about their motherboard pin-outs for peripherals (such as MMC readers and power on/off switches and LEDs).
With what kind of parts were consumers able to upgrade their Dell systems with?
A: Dell-compatible parts

Context and question: Historically, the channel's programming consisted mainly of featured classic theatrically released feature films from the Turner Entertainment film library which comprises films from Warner Bros. Pictures (covering films released before 1950) and Metro-Goldwyn-Mayer (covering films released before May 1986). However, TCM now has licensing deals with other Hollywood film studios as well as its Time Warner sister company, Warner Bros. (which now controls the Turner Entertainment library and its own later films), and occasionally shows more recent films. Turner Classic Movies is a dedicated film channel and is available in United States, United Kingdom, France (TCM Cinema), Spain (TCM Espana), Nordic countries, Middle East and Africa.
Up until what month and year of release are films from TCM part of the Turner Entertainment Library?
Answer: unanswerable

Question: The Houston area has over 150 active faults (estimated to be 300 active faults) with an aggregate length of up to 310 miles (500 km), including the Long PointEureka Heights fault system which runs through the center of the city. There have been no significant historically recorded earthquakes in Houston, but researchers do not discount the possibility of such quakes having occurred in the deeper past, nor occurring in the future. Land in some areas southeast of Houston is sinking because water has been pumped out of the ground for many years. It may be associated with slip along the faults; however, the slippage is slow and not considered an earthquake, where stationary faults must slip suddenly enough to create seismic waves. These faults also tend to move at a smooth rate in what is termed "fault creep", which further reduces the risk of an earthquake.
Is there an answer to this question: What geological feature has been placed underground to cause sinking in areas of southeast Houston?

Answer: unanswerable

QUES: The organizational structure as shown above is responsible for the peacetime organization, equipping, and training of aerospace units for operational missions. When required to support operational missions, the Secretary of Defense (SECDEF) directs the Secretary of the Air Force (SECAF) to execute a Change in Operational Control (CHOP) of these units from their administrative alignment to the operational command of a Regional Combatant Commander (CCDR). In the case of AFSPC, AFSOC, PACAF, and USAFE units, forces are normally employed in-place under their existing CCDR. Likewise, AMC forces operating in support roles retain their componency to USTRANSCOM unless chopped to a Regional CCDR.

What does the abbreviation CHOP stand for?
