Problem: British Isles:

Ireland and the United Kingdom are both part of the European Union (EU). The Crown Dependencies are not a part of the EU however do participate in certain aspects that were negotiated as a part of the UK's accession to the EU. Neither the United Kingdom or Ireland are part of the Schengen area, that allow passport-free travel between EU members states. However, since the partition of Ireland, an informal free-travel area had existed across the region. In 1997, this area required formal recognition during the course of negotiations for the Amsterdam Treaty of the European Union and is now known as the Common Travel Area.

What type of travel does the Amsterdam Treaty area allow?

Problem: In England, the 16th-century European Reformation resulted in a number of executions on charges of heresy. During the thirty-eight years of Henry VIII's reign, about sixty heretics, mainly Protestants, were executed and a rather greater number of Catholics lost their lives on grounds of political offences such as treason, notably Sir Thomas More and Cardinal John Fisher, for refusing to accept the king's supremacy over the Church in England. Under Edward VI, the heresy laws were repealed in 1547 only to be reintroduced in 1554 by Mary I; even so two radicals were executed in Edward's reign (one for denying the reality of the incarnation, the other for denying Christ's divinity). Under Mary, around two hundred and ninety people were burned at the stake between 1555 and 1558 after the restoration of papal jurisdiction. When Elizabeth I came to the throne, the concept of heresy was retained in theory but severely restricted by the 1559 Act of Supremacy and the one hundred and eighty or so Catholics who were executed in the forty-five years of her reign were put to death because they were considered members of "...a subversive fifth column." The last execution of a "heretic" in England occurred under James VI and I in 1612. Although the charge was technically one of "blasphemy" there was one later execution in Scotland (still at that date an entirely independent kingdom) when in 1697 Thomas Aikenhead was accused, among other things, of denying the doctrine of the Trinity.
What event in England during the 16th century had an outcome of many deaths for heresy?

Answer: European Reformation


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Hydrostatic gauges (such as the mercury column manometer) consist of a vertical column of liquid in a tube whose ends are exposed to different pressures. The column will rise or fall until its weight is in equilibrium with the pressure differential between the two ends of the tube. The simplest design is a closed-end U-shaped tube, one side of which is connected to the region of interest. Any fluid can be used, but mercury is preferred for its high density and low vapour pressure. Simple hydrostatic gauges can measure pressures ranging from 1 torr (100 Pa) to above atmospheric. An important variation is the McLeod gauge which isolates a known volume of vacuum and compresses it to multiply the height variation of the liquid column. The McLeod gauge can measure vacuums as high as 10−6 torr (0.1 mPa), which is the lowest direct measurement of pressure that is possible with current technology. Other vacuum gauges can measure lower pressures, but only indirectly by measurement of other pressure-controlled properties. These indirect measurements must be calibrated via a direct measurement, most commonly a McLeod gauge.
What is the lowest amount of mercury that can be measured in the air?
A: unanswerable


Context and question: Title VII was perhaps the most controversial of the entire bill. Many conservatives accused it of advocating a de facto quota system, and claimed unconstitutionality as it attempts to regulate the workplace. Minnesota Senator Hubert Humphrey corrected this notion: "there is nothing in [Title VII] that will give power to the Commission to require hiring, firing, and promotion to meet a racial 'quota.' [. . .] Title VII is designed to encourage the hiring on basis of ability and qualifications, not race or religion." Title VII prohibits discrimination. Humphrey was the silent hero of the bill's passing through Congress. He pledged that the bill required no quotas, just nondiscrimination. Doing so, he convinced many pro-business Republicans, including Senate Minority Leader Everett Dirksen (IL) to support Title VII.:78–80
 Who was one of the key members that Humphrey managed to convince to reject the bill?
Answer: unanswerable


Question: In the midst of the European sovereign-debt crisis, Radek Sikorski, Poland's Foreign Minister, stated in November 2011, "I will probably be the first Polish foreign minister in history to say so, but here it is: I fear German power less than I am beginning to fear German inactivity. You have become Europe's indispensable nation." According to Jacob Heilbrunn, a senior editor at The National Interest, such a statement is unprecedented when taking into consideration Germany's history. "This was an extraordinary statement from a top official of a nation that was ravaged by Germany during World War II. And it reflects a profound shift taking place throughout Germany and Europe about Berlin's position at the center of the Continent." Heilbrunn believes that the adage, "what was good for Germany was bad for the European Union" has been supplanted by a new mentality—what is in the interest of Germany is also in the interest of its neighbors. The evolution in Germany's national identity stems from focusing less on its Nazi past and more on its Prussian history, which many Germans believe was betrayed—and not represented—by Nazism. The evolution is further precipitated by Germany's conspicuous position as Europe's strongest economy. Indeed, this German sphere of influence has been welcomed by the countries that border it, as demonstrated by Polish foreign minister Radek Sikorski's effusive praise for his country's western neighbor. This shift in thinking is boosted by a newer generation of Germans who see World War II as a distant memory.
Is there an answer to this question: What Polish foreign minister said he feared German power?

Answer: unanswerable


Question: The 1850 census saw a dramatic shift in the way information about residents was collected. For the first time, free persons were listed individually instead of by head of household. There were two questionnaires: one for free inhabitants and one for slaves. The question on the free inhabitants schedule about color was a column that was to be left blank if a person was white, marked "B" if a person was black, and marked "M" if a person was mulatto. Slaves were listed by owner, and classified by gender and age, not individually, and the question about color was a column that was to be marked with a "B" if the slave was black and an "M" if mulatto.
Is there an answer to this question: In the 1850 US census, what was put into the color column for black persons?

Answer:
B
