Problem: East Prussia:

Following Nazi Germany's defeat in World War II in 1945, East Prussia was partitioned between Poland and the Soviet Union according to the Potsdam Conference. Southern East Prussia was placed under Polish administration, while northern East Prussia was divided between the Soviet republics of Russia (the Kaliningrad Oblast) and Lithuania (the constituent counties of the Klaipeda Region). The city of Konigsberg was renamed Kaliningrad in 1946. The German population of the province largely evacuated during the war, but several hundreds of thousands died during the years 194446 and the remainder were subsequently expelled.

In what year did the Potsdam Conference occur?

A: unanswerable

Problem: In non-relativistic classical mechanics, Newton's concept of "relative, apparent, and common time" can be used in the formulation of a prescription for the synchronization of clocks. Events seen by two different observers in motion relative to each other produce a mathematical concept of time that works sufficiently well for describing the everyday phenomena of most people's experience. In the late nineteenth century, physicists encountered problems with the classical understanding of time, in connection with the behavior of electricity and magnetism. Einstein resolved these problems by invoking a method of synchronizing clocks using the constant, finite speed of light as the maximum signal velocity. This led directly to the result that observers in motion relative to one another measure different elapsed times for the same event.
Who's concept can be used to synchronize the use of electricity?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Richard Hurd believed that Burke's imitation was near-perfect and that this defeated his purpose: an ironist "should take care by a constant exaggeration to make the ridicule shine through the Imitation. Whereas this Vindication is everywhere enforc'd, not only in the language, and on the principles of L. Bol., but with so apparent, or rather so real an earnestness, that half his purpose is sacrificed to the other". A minority of scholars have taken the position that, in fact, Burke did write the Vindication in earnest, later disowning it only for political reasons.
Why did a few scholars think Burke hadn't intended his book as a satire yet later claimed it was a satire?
A: political reasons

Context and question: The New Zealand police attempted to arrest one of the leaders in the demonstration. When he resisted, a struggle developed between the police and the Mau. The officers began to fire randomly into the crowd and a Lewis machine gun, mounted in preparation for this demonstration, was used to disperse the demonstrators. Chief Tamasese was shot from behind and killed while trying to bring calm and order to the Mau demonstrators, screaming "Peace, Samoa". Ten others died that day and approximately 50 were injured by gunshot wounds and police batons. That day would come to be known in Samoa as Black Saturday. The Mau grew, remaining steadfastly non-violent, and expanded to include a highly influential women's branch.
What do Samoans call the historical day of the Mau demonstration?
Answer: Black Saturday

Question: The development of the appreciation medals was initiated by the White House and executed by the Bureau of the Mint through the U.S. Mint in Philadelphia. The medals were struck from September 1958 through October 1960. A total of twenty designs are cataloged with a total mintage of 9,858. Each of the designs incorporates the text "with appreciation" or "with personal and official gratitude" accompanied with Eisenhower's initials "D.D.E." or facsimile signature. The design also incorporates location, date, and/or significant event. Prior to the end of his second term as President, 1,451 medals were turned-in to the Bureau of the Mint and destroyed. The Eisenhower appreciation medals are part of the Presidential Medal of Appreciation Award Medal Series.
Is there an answer to this question: In what city were the appreciation medals minted?

Answer: Philadelphia

Problem: 2008 Sichuan earthquake:

An article in Science suggested that the construction and filling of the Zipingpu Dam may have triggered the earthquake. The chief engineer of the Sichuan Geology and Mineral Bureau said that the sudden shift of a huge quantity of water into the region could have relaxed the tension between the two sides of the fault, allowing them to move apart, and could have increased the direct pressure on it, causing a violent rupture. The effect was "25 times more" than a year's worth of natural stress from tectonic movement. The government had disregarded warnings about so many large-scale dam projects in a seismically active area. Researchers have been denied access to seismological and geological data to examine the cause of the quake further.

What have researchers been denied?
---
A:
access to seismological and geological data
