Problem: East Prussia:

The Kingdom of Prussia became the leading state of the German Empire after its creation in 1871. However, the Treaty of Versailles following World War I granted West Prussia to Poland and made East Prussia an exclave of Weimar Germany (the new Polish Corridor separating East Prussia from the rest of Germany), while the Memel Territory was detached and was annexed by Lithuania in 1923. Following Nazi Germany's defeat in World War II in 1945, war-torn East Prussia was divided at Joseph Stalin's insistence between the Soviet Union (the Kaliningrad Oblast in the Russian SFSR and the constituent counties of the Klaipeda Region in the Lithuanian SSR) and the People's Republic of Poland (the Warmian-Masurian Voivodeship). The capital city Konigsberg was renamed Kaliningrad in 1946. The German population of the province was largely evacuated during the war or expelled shortly thereafter in the expulsion of Germans after World War II. An estimated 300,000 (around one fifth of the population) died either in war time bombings raids or in the battles to defend the province.[citation needed]

Problem: The trip was intended to soften the strong isolationist tendencies among the North American public with regard to the developing tensions in Europe. Although the aim of the tour was mainly political, to shore up Atlantic support for the United Kingdom in any future war, the King and Queen were enthusiastically received by the public. The fear that George would be compared unfavourably to his predecessor, Edward VIII, was dispelled. They visited the 1939 New York World's Fair and stayed with President Franklin D. Roosevelt at the White House and at his private estate at Hyde Park, New York. A strong bond of friendship was forged between the King and Queen and the President during the tour, which had major significance in the relations between the United States and the United Kingdom through the ensuing war years.
What kind of tendencies did North America have?

Answer: isolationist tendencies

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Somerset has 11,500 listed buildings, 523 scheduled monuments, 192 conservation areas, 41 parks and gardens including those at Barrington Court, Holnicote Estate, Prior Park Landscape Garden and Tintinhull Garden, 36 English Heritage sites and 19 National Trust sites, including Clevedon Court, Fyne Court, Montacute House and Tyntesfield as well as Stembridge Tower Mill, the last remaining thatched windmill in England. Other historic houses in the county which have remained in private ownership or used for other purposes include Halswell House and Marston Bigot. A key contribution of Somerset architecture is its medieval church towers. Jenkins writes, "These structures, with their buttresses, bell-opening tracery and crowns, rank with Nottinghamshire alabaster as England's finest contribution to medieval art."
What is the most visited park and garden in Somerset?
A: unanswerable

Context and question: Following the breakup of the Russian Empire in the aftermath of World War I for a brief period, from 1918 to 1920, Armenia was an independent republic. In late 1920, the communists came to power following an invasion of Armenia by the Red Army, and in 1922, Armenia became part of the Transcaucasian SFSR of the Soviet Union, later forming the Armenian Soviet Socialist Republic (1936 to September 21, 1991). In 1991, Armenia declared independence from the USSR and established the second Republic of Armenia.
Who invaded Armenia in 1920?
Answer: the Red Army

Question: In physics, the standard definition of a glass (or vitreous solid) is a solid formed by rapid melt quenching. The term glass is often used to describe any amorphous solid that exhibits a glass transition temperature Tg. If the cooling is sufficiently rapid (relative to the characteristic crystallization time) then crystallization is prevented and instead the disordered atomic configuration of the supercooled liquid is frozen into the solid state at Tg. The tendency for a material to form a glass while quenched is called glass-forming ability. This ability can be predicted by the rigidity theory. Generally, the structure of a glass exists in a metastable state with respect to its crystalline form, although in certain circumstances, for example in atactic polymers, there is no crystalline analogue of the amorphous phase.
Is there an answer to this question: What predicts glass-forming ability?

Answer: rigidity theory

The inclusiveness of Weinreich's definition (above) directs attention to the totality of one's identity at a given phase in time, and assists in elucidating component aspects of one's total identity, such as one's gender identity, ethnic identity, occupational identity and so on. The definition readily applies to the young child, to the adolescent, to the young adult, and to the older adult in various phases of the life cycle. Depending on whether one is a young child or an adult at the height of one's powers, how one construes oneself as one was in the past will refer to very different salient experiential markers. Likewise, how one construes oneself as one aspires to be in the future will differ considerably according to one's age and accumulated experiences. (Weinreich & Saunderson, (eds) 2003, pp 2634).
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How one construes oneself now and in the future differs considerably because of what 2 things?
Ah, so..
age and accumulated experiences
