Problem: Windows 8:

The developers of both Chrome and Firefox committed to developing Metro-style versions of their browsers; while Chrome's "Windows 8 mode" uses a full-screen version of the existing desktop interface, Firefox's version (which was first made available on the "Aurora" release channel in September 2013) uses a touch-optimized interface inspired by the Android version of Firefox. In October 2013, Chrome's app was changed to mimic the desktop environment used by Chrome OS. Development of the Firefox app for Windows 8 has since been cancelled, citing a lack of user adoption for the beta versions.

When was Firefox's version of Windows 9 made accesible?

A: unanswerable


Problem: Historical studies reveal that policing agents have undertaken a variety of cross-border police missions for many years (Deflem, 2002). For example, in the 19th century a number of European policing agencies undertook cross-border surveillance because of concerns about anarchist agitators and other political radicals. A notable example of this was the occasional surveillance by Prussian police of Karl Marx during the years he remained resident in London. The interests of public police agencies in cross-border co-operation in the control of political radicalism and ordinary law crime were primarily initiated in Europe, which eventually led to the establishment of Interpol before the Second World War. There are also many interesting examples of cross-border policing under private auspices and by municipal police forces that date back to the 19th century (Nadelmann, 1993). It has been established that modern policing has transgressed national boundaries from time to time almost from its inception. It is also generally agreed that in the post–Cold War era this type of practice became more significant and frequent (Sheptycki, 2000).
In what era did cross-border policing increase?

Answer: post–Cold War


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
In 1977, Elizabeth marked the Silver Jubilee of her accession. Parties and events took place throughout the Commonwealth, many coinciding with her associated national and Commonwealth tours. The celebrations re-affirmed the Queen's popularity, despite virtually coincident negative press coverage of Princess Margaret's separation from her husband. In 1978, the Queen endured a state visit to the United Kingdom by Romania's communist dictator, Nicolae Ceaușescu, and his wife, Elena, though privately she thought they had "blood on their hands". The following year brought two blows: one was the unmasking of Anthony Blunt, former Surveyor of the Queen's Pictures, as a communist spy; the other was the assassination of her relative and in-law Lord Mountbatten by the Provisional Irish Republican Army.
In what year did Nicolae Ceausescu become the communist dictator of Romania?
A: unanswerable


Context and question: 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.
What would have led to the starvation of 80 million people in the Soviet Union?
Answer: The Nazi Hunger Plan and Generalplan Ost


Question: The other large cemeteries are the Cementerio del Buceo, Cementerio del Cerro, and Cementerio Paso Molino. The British Cemetery Montevideo (Cementerio Británico) is another of the oldest cemeteries in Uruguay, located in the Buceo neighborhood. Many noblemen and eminent persons are buried there. The cemetery originated when the Englishman Mr. Thomas Samuel Hood purchased a plot of land in the name of the English residents in 1828. However, in 1884 the government compensated the British by moving the cemetery to Buceo to accommodate city growth. A section of the cemetery, known as British Cemetery Montevideo Soldiers and Sailors, contains the graves of quite a number of sailors of different nationalities, although the majority are of British descent. One United States Marine, Henry de Costa, is buried here.
Is there an answer to this question: When did Mr. Thomas Samuel Hood purchase a plot of land at the British Cemetery Montevideo? 

Answer: 1828


Question: Synapses are the key functional elements of the brain. The essential function of the brain is cell-to-cell communication, and synapses are the points at which communication occurs. The human brain has been estimated to contain approximately 100 trillion synapses; even the brain of a fruit fly contains several million. The functions of these synapses are very diverse: some are excitatory (exciting the target cell); others are inhibitory; others work by activating second messenger systems that change the internal chemistry of their target cells in complex ways. A large number of synapses are dynamically modifiable; that is, they are capable of changing strength in a way that is controlled by the patterns of signals that pass through them. It is widely believed that activity-dependent modification of synapses is the brain's primary mechanism for learning and memory.
Is there an answer to this question: The fruit fly has a brain that has how many synapses?

Answer:
several million
