Problem: Philadelphia:

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.

What was the grad rate in 2005?
---
A: 52%


Problem: In 1988, unrest over economic mismanagement and political oppression by the government led to widespread pro-democracy demonstrations throughout the country known as the 8888 Uprising. Security forces killed thousands of demonstrators, and General Saw Maung staged a coup d'état and formed the State Law and Order Restoration Council (SLORC). In 1989, SLORC declared martial law after widespread protests. The military government finalised plans for People's Assembly elections on 31 May 1989. SLORC changed the country's official English name from the "Socialist Republic of the Union of Burma" to the "Union of Myanmar" in 1989.
Why was marshal law declared in Burma in 1989?
---
Answer: declared martial law after widespread protests.


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The assumption that black-body radiation is thermal leads to an accurate prediction: the total amount of emitted energy goes up with the temperature according to a definite rule, the Stefan–Boltzmann law (1879–84). But it was also known that the colour of the light given off by a hot object changes with the temperature, so that "white hot" is hotter than "red hot". Nevertheless, Wilhelm Wien discovered the mathematical relationship between the peaks of the curves at different temperatures, by using the principle of adiabatic invariance. At each different temperature, the curve is moved over by Wien's displacement law (1893). Wien also proposed an approximation for the spectrum of the object, which was correct at high frequencies (short wavelength) but not at low frequencies (long wavelength). It still was not clear why the spectrum of a hot object had the form that it has (see diagram).
What characteristic of the light emitted by a hot object changes with temperature?
A: the colour of the light given off


Context and question: In the early hours of 7 December (Hawaiian time), Japan launched a major surprise carrier-based air strike on Pearl Harbor without explicit warning, which crippled the U.S. Pacific Fleet, leaving eight American battleships out of action, 188 American aircraft destroyed, and 2,403 American citizens dead. At the time of the attack, the U.S. was not officially at war anywhere in the world, which means that the people killed or property destroyed at Pearl Harbor by the Japanese attack had a non-combatant status.[nb 11] The Japanese had gambled that the United States, when faced with such a sudden and massive blow, would agree to a negotiated settlement and allow Japan free rein in Asia. This gamble did not pay off. American losses were less serious than initially thought: The American aircraft carriers, which would prove to be more important than battleships, were at sea, and vital naval infrastructure (fuel oil tanks, shipyard facilities, and a power station), submarine base, and signals intelligence units were unscathed. Japan's fallback strategy, relying on a war of attrition to make the U.S. come to terms, was beyond the IJN's capabilities.
How many Americans died in the Pearl Harbor attacks?
Answer: 2,403


Question: Kadamba (345 – 525 CE) was an ancient royal dynasty of Karnataka, India that ruled northern Karnataka and the Konkan from Banavasi in present-day Uttara Kannada district. At the peak of their power under King Kakushtavarma, the Kadambas of Banavasi ruled large parts of modern Karnataka state. The dynasty was founded by Mayurasharma in 345 CE which at later times showed the potential of developing into imperial proportions, an indication to which is provided by the titles and epithets assumed by its rulers. King Mayurasharma defeated the armies of Pallavas of Kanchi possibly with help of some native tribes. The Kadamba fame reached its peak during the rule of Kakusthavarma, a notable ruler with whom even the kings of Gupta Dynasty of northern India cultivated marital alliances. The Kadambas were contemporaries of the Western Ganga Dynasty and together they formed the earliest native kingdoms to rule the land with absolute autonomy. The dynasty later continued to rule as a feudatory of larger Kannada empires, the Chalukya and the Rashtrakuta empires, for over five hundred years during which time they branched into minor dynasties known as the Kadambas of Goa, Kadambas of Halasi and Kadambas of Hangal.
Is there an answer to this question: During what time did Kadamba rule northern Karnataka?

Answer: 345 – 525 CE


Question: The positions on the persistence of objects are somewhat similar. An endurantist holds that for an object to persist through time is for it to exist completely at different times (each instance of existence we can regard as somehow separate from previous and future instances, though still numerically identical with them). A perdurantist on the other hand holds that for a thing to exist through time is for it to exist as a continuous reality, and that when we consider the thing as a whole we must consider an aggregate of all its "temporal parts" or instances of existing. Endurantism is seen as the conventional view and flows out of our pre-philosophical ideas (when I talk to somebody I think I am talking to that person as a complete object, and not just a part of a cross-temporal being), but perdurantists have attacked this position. (An example of a perdurantist is David Lewis.) One argument perdurantists use to state the superiority of their view is that perdurantism is able to take account of change in objects.
Is there an answer to this question: What does endurantism take account of the change in?

Answer:
unanswerable
