Problem: Frederic Chopin:

Chopin arrived in Paris in late September 1831; he would never return to Poland, thus becoming one of many expatriates of the Polish Great Emigration. In France he used the French versions of his given names, and after receiving French citizenship in 1835, he travelled on a French passport. However, Chopin remained close to his fellow Poles in exile as friends and confidants and he never felt fully comfortable speaking French. Chopin's biographer Adam Zamoyski writes that he never considered himself to be French, despite his father's French origins, and always saw himself as a Pole.

In what year did Chopin become a French citizen?

A: 1835

Problem: While the original Xbox sold poorly in Japan, selling just 2 million units while it was on the market (between 2002 and 2005),[citation needed] the Xbox 360 sold even more poorly, selling only 1.5 million units from 2005 to 2011. Edge magazine reported in August 2011 that initially lackluster and subsequently falling sales in Japan, where Microsoft had been unable to make serious inroads into the dominance of domestic rivals Sony and Nintendo, had led to retailers scaling down and in some cases discontinuing sales of the Xbox 360 completely.
When did Edge report Sony sales were falling?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Later the Muslims invaded Spain (711), but the Arabs and Moors never managed to have any real control over Galicia, which was later incorporated into the expanding Christian Kingdom of Asturias, usually known as Gallaecia or Galicia (Yilliqiya and Galisiya) by Muslim Chroniclers, as well as by many European contemporaries. This era consolidated Galicia as a Christian society which spoke a Romance language. During the next century Galician noblemen took northern Portugal, conquering Coimbra in 871, thus freeing what were considered the southernmost city of ancient Galicia.
As a result, what became the religion of Galician society?
A: Christian

Context and question: Roncalli was elected pope on 28 October 1958 at age 76 after 11 ballots. His selection was unexpected, and Roncalli himself had come to Rome with a return train ticket to Venice. He was the first pope to take the pontifical name of "John" upon election in more than 500 years, and his choice settled the complicated question of official numbering attached to this papal name due to the antipope of this name. Pope John XXIII surprised those who expected him to be a caretaker pope by calling the historic Second Vatican Council (196265), the first session opening on 11 October 1962. His passionate views on equality were summed up in his famous statement, "We were all made in God's image, and thus, we are all Godly alike." John XXIII made many passionate speeches during his pontificate, one of which was on the day that he opened the Second Vatican Council in the middle of the night to the crowd gathered in St. Peter's Square: "Dear children, returning home, you will find children: give your children a hug and say: This is a hug from the Pope!"
How long has there been a Pope in Rome?
Answer: unanswerable

Question: The Earth of the early Archean (4,000 to 2,500 million years ago) may have had a different tectonic style. During this time, the Earth's crust cooled enough that rocks and continental plates began to form. Some scientists think because the Earth was hotter, that plate tectonic activity was more vigorous than it is today, resulting in a much greater rate of recycling of crustal material. This may have prevented cratonisation and continent formation until the mantle cooled and convection slowed down. Others argue that the subcontinental lithospheric mantle is too buoyant to subduct and that the lack of Archean rocks is a function of erosion and subsequent tectonic events.
Is there an answer to this question: During what period did the earths crust cooling allow the creation of plates?

Answer: Archean

Problem: Thuringia:

The Thuringian population has a significant sex ratio gap, caused by the emigration of young women, especially in rural areas. Overall, there are 115 to 120 men per 100 women in the 2540 age group ("family founders") which has negative consequences for the birth ratio. Furthermore, the population is getting older and older with some rural municipalities recording more than 30% of over-65s (pensioners). This is a problem for the regional labour market, as there are twice as many people leaving as entering the job market annually.

How many citizens of Thuringia are dead before the age of 65?
