Problem: United States Army:

Starting in 1910, the army began acquiring fixed-wing aircraft. In 1910, Mexico was having a civil war, peasant rebels fighting government soldiers. The army was deployed to American towns near the border to ensure safety to lives and property. In 1916, Pancho Villa, a major rebel leader, attacked Columbus, New Mexico, prompting a U.S. intervention in Mexico until 7 February 1917. They fought the rebels and the Mexican federal troops until 1918. The United States joined World War I in 1917 on the side of Britain, France, Russia, Italy and other allies. U.S. troops were sent to the Western Front and were involved in the last offensives that ended the war. With the armistice in November 1918, the army once again decreased its forces.

Problem: The style of Georgian buildings is very variable, but marked by a taste for symmetry and proportion based on the classical architecture of Greece and Rome, as revived in Renaissance architecture. Ornament is also normally in the classical tradition, but typically rather restrained, and sometimes almost completely absent on the exterior. The period brought the vocabulary of classical architecture to smaller and more modest buildings than had been the case before, replacing English vernacular architecture (or becoming the new vernacular style) for almost all new middle-class homes and public buildings by the end of the period.
What classical architecture is Georgian architecture based on?
---
Answer: Greece and Rome


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
In addition there are two service bells, cast by Robert Mot, in 1585 and 1598 respectively, a Sanctus bell cast in 1738 by Richard Phelps and Thomas Lester and two unused bells—one cast about 1320, by the successor to R de Wymbish, and a second cast in 1742, by Thomas Lester. The two service bells and the 1320 bell, along with a fourth small silver "dish bell", kept in the refectory, have been noted as being of historical importance by the Church Buildings Council of the Church of England.
When was the Sanctus bell cast?
A: 1738

Question: In British English, the word 'asphalt' is used to refer to a mixture of mineral aggregate and asphalt/bitumen (also called tarmac in common parlance). When bitumen is mixed with clay it is usually called asphaltum. The earlier word 'asphaltum' is now archaic and not commonly used.[citation needed] In American English, 'asphalt' is equivalent to the British 'bitumen'. However, 'asphalt' is also commonly used as a shortened form of 'asphalt concrete' (therefore equivalent to the British 'asphalt' or 'tarmac'). In Australian English, bitumen is often used as the generic term for road surfaces. In Canadian English, the word bitumen is used to refer to the vast Canadian deposits of extremely heavy crude oil, while asphalt is used for the oil refinery product used to pave roads and manufacture roof shingles and various waterproofing products. Diluted bitumen (diluted with naphtha to make it flow in pipelines) is known as dilbit in the Canadian petroleum industry, while bitumen "upgraded" to synthetic crude oil is known as syncrude and syncrude blended with bitumen as synbit. Bitumen is still the preferred geological term for naturally occurring deposits of the solid or semi-solid form of petroleum. Bituminous rock is a form of sandstone impregnated with bitumen. The tar sands of Alberta, Canada are a similar material.
Is there an answer to this question: Which is the preferred geographical term for natural deposits?

Answer: unanswerable


During World War II, Hitler's Generalplan Ost (general plan for the East) entailed killing, deporting, or enslaving the Slavic and Jewish population of occupied Eastern Europe to create Lebensraum (living space) for German settlers. The Nazi Hunger Plan and Generalplan Ost would have led to the starvation of 80 million people in the Soviet Union. These partially fulfilled plans resulted in the deaths of an estimated 19.3 million civilians and prisoners of war.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What would have led to the starvation of 80 million people in the Soviet Union?
Ah, so..
The Nazi Hunger Plan and Generalplan Ost
