Problem: PlayStation 3:

In January 2008, Kaz Hirai, CEO of Sony Computer Entertainment, suggested that the console may start making a profit by early 2009, stating that, "the next fiscal year starts in April and if we can try to achieve that in the next fiscal year that would be a great thing" and that "[profitability] is not a definite commitment, but that is what I would like to try to shoot for". However, market analysts Nikko Citigroup have predicted that PlayStation 3 could be profitable by August 2008. In a July 2008 interview, Hirai stated that his objective is for PlayStation 3 to sell 150 million units by its ninth year, surpassing PlayStation 2's sales of 140 million in its nine years on the market. In January 2009 Sony announced that their gaming division was profitable in Q3 2008.

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
During the Early Modern period (approximately late 15th century to 1800), the universities of Europe would see a tremendous amount of growth, productivity and innovative research. At the end of the Middle Ages, about 400 years after the first university was founded, there were twenty-nine universities spread throughout Europe. In the 15th century, twenty-eight new ones were created, with another eighteen added between 1500 and 1625. This pace continued until by the end of the 18th century there were approximately 143 universities in Europe and Eastern Europe, with the highest concentrations in the German Empire (34), Italian countries (26), France (25), and Spain (23) – this was close to a 500% increase over the number of universities toward the end of the Middle Ages. This number does not include the numerous universities that disappeared, or institutions that merged with other universities during this time. It should be noted that the identification of a university was not necessarily obvious during the Early Modern period, as the term is applied to a burgeoning number of institutions. In fact, the term "university" was not always used to designate a higher education institution. In Mediterranean countries, the term studium generale was still often used, while "Academy" was common in Northern European countries.
How many universities exicted across Europe by the end of the 1800's?
A: unanswerable

Question: Elizabeth's personal fortune has been the subject of speculation for many years. Jock Colville, who was her former private secretary and a director of her bank, Coutts, estimated her wealth in 1971 at £2 million (equivalent to about £25 million today).

The Sunday Times Rich List 2015 estimated her private wealth at £340 million, making her the 302nd richest person in the UK.
Is there an answer to this question: In what year did Jock Colville become Elizabeth's private secretary?

Answer: unanswerable


Problem: Time:

Greenwich Mean Time (GMT) is an older standard, adopted starting with British railways in 1847. Using telescopes instead of atomic clocks, GMT was calibrated to the mean solar time at the Royal Observatory, Greenwich in the UK. Universal Time (UT) is the modern term for the international telescope-based system, adopted to replace "Greenwich Mean Time" in 1928 by the International Astronomical Union. Observations at the Greenwich Observatory itself ceased in 1954, though the location is still used as the basis for the coordinate system. Because the rotational period of Earth is not perfectly constant, the duration of a second would vary if calibrated to a telescope-based standard like GMT or UT—in which a second was defined as a fraction of a day or year. The terms "GMT" and "Greenwich Mean Time" are sometimes used informally to refer to UT or UTC.

When was GMT adopted by the International Astronomical Union?
