Input: Read this: In 1579 the northern seven provinces signed the Union of Utrecht, in which they decided to join forces against Spanish rule. The Union of Utrecht is seen as the beginning of the Dutch Republic. In 1580 the new and predominantly Protestant state abolished the bishoprics, including the archbishopric of Utrecht. The stadtholders disapproved of the independent course of the Utrecht bourgeoisie and brought the city under much more direct control of the republic; which shifted the power towards its dominant province Holland. This was the start of a long period of stagnation of trade and development in Utrecht. Utrecht remained an atypical city in the new republic with about 40% Catholic in the mid-17th century, and even more among the elite groups, who included many rural nobility and gentry with town houses there.
Question: Who signed the Union of Utrecht in the 15th century?

Output: unanswerable


QUES: The CBC's flagship newscast, The National, airs Sunday through Fridays at 10:00 p.m. EST and Saturdays at 6:00 p.m. EST. Until October 2006, CBC owned-and-operated stations aired a second broadcast of the program at 11:00 p.m.; this later broadcast included only the main news portion of the program, and excluded the analysis and documentary segment. This second airing was later replaced with other programming, and as of the 2012-13 television season, was replaced on CBC's major market stations by a half-hour late newscast. There is also a short news update, at most, on late Saturday evenings. During hockey season, this update is usually found during the first intermission of the second game of the doubleheader on Hockey Night in Canada.

During hockey season, when does the late night news update occur?
What is the answer?
ANS: during the first intermission of the second game of the doubleheader on Hockey Night in Canada


QUES: A different format, CD-4 (not to be confused with compact disc), by RCA, encoded the front-rear difference information on an ultrasonic carrier, which required a special wideband cartridge to capture it on carefully calibrated pickup arm/turntable combinations. CD-4 was even less successful than the two matrixed formats. (A further problem was that no cutting heads were available that could handle the HF information. That was remedied by cutting at half the speed. Later, the special half-speed cutting heads and equalization techniques were employed to get a wider frequency response in stereo with reduced distortion and greater headroom.)
How widespread was the success of CD-4 format? 

ANS: even less successful than the two matrixed formats


Graduation rates among district-run schools, meanwhile, have steadily increased in the last ten years. In 2005, Philadelphia had a district graduation rate of 52%. This number has increased to 65% in 2014, still below the national and state averages. Scores on the state's standardized test, the Pennsylvania System of School Assessment (PSSA) have trended upward from 2005 to 2011 but have decreased since. In 2005, the district-run schools scored an average of 37.4% on math and 35.5% on reading. The city's schools reached its peak scores in 2011 with 59.0% on math and 52.3% on reading. In 2014, the scores dropped significantly to 45.2% on math and 42.0% on reading.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Is that the above or below the national average?
Ah, so.. below the national and state averages


Question: Today, Greeks are the majority ethnic group in the Hellenic Republic, where they constitute 93% of the country's population, and the Republic of Cyprus where they make up 78% of the island's population (excluding Turkish settlers in the occupied part of the country). Greek populations have not traditionally exhibited high rates of growth; nonetheless, the population of Greece has shown regular increase since the country's first census in 1828. A large percentage of the population growth since the state's foundation has resulted from annexation of new territories and the influx of 1.5 million Greek refugees after the 1923 population exchange between Greece and Turkey. About 80% of the population of Greece is urban, with 28% concentrated in the city of Athens
Try to answer this question if possible: What's the estimated populace of Irish on the isle of Cyprus?
Answer: unanswerable


Context and question: The Quran most likely existed in scattered written form during Muhammad's lifetime. Several sources indicate that during Muhammad's lifetime a large number of his companions had memorized the revelations. Early commentaries and Islamic historical sources support the above-mentioned understanding of the Quran's early development. The Quran in its present form is generally considered by academic scholars to record the words spoken by Muhammad because the search for variants has not yielded any differences of great significance.[page needed] University of Chicago professor Fred Donner states that "...there was a very early attempt to establish a uniform consonantal text of the Qurʾān from what was probably a wider and more varied group of related texts in early transmission. [...] After the creation of this standardized canonical text, earlier authoritative texts were suppressed, and all extant manuscripts—despite their numerous variants—seem to date to a time after this standard consonantal text was established." Although most variant readings of the text of the Quran have ceased to be transmitted, some still are. There has been no critical text produced on which a scholarly reconstruction of the Quranic text could be based. Historically, controversy over the Quran's content has rarely become an issue, although debates continue on the subject.
What was done to the Quranic text late in its history leaving few markedly different variants?
Answer:
unanswerable
