Problem: East Prussia:

In the 1772 First Partition of Poland, the Prussian king Frederick the Great annexed neighboring Royal Prussia, i.e. the Polish voivodeships of Pomerania (Gdańsk Pomerania or Pomerelia), Malbork, Chełmno and the Prince-Bishopric of Warmia, thereby bridging the "Polish Corridor" between his Prussian and Farther Pomeranian lands and cutting remaining Poland off the Baltic Coast. The territory of Warmia was incorporated into the lands of former Ducal Prussia, which, by administrative deed of 31 January 1773 were named East Prussia. The former Polish Pomerelian lands beyond the Vistula River together with Malbork and Chełmno Land formed the Province of West Prussia with its capital at Marienwerder (Kwidzyn). The Polish Partition Sejm ratified the cession on 30 September 1773, whereafter Frederick officially went on to call himself a King "of" Prussia.

What was ratified in 1773 in Prussia?

A: The Polish Partition Sejm


Problem: The conventional merit-system degree is currently not as common in open education as it is in campus universities, although some open universities do already offer conventional degrees such as the Open University in the United Kingdom. Presently, many of the major open education sources offer their own form of certificate. Due to the popularity of open education, these new kind of academic certificates are gaining more respect and equal "academic value" to traditional degrees. Many open universities are working to have the ability to offer students standardized testing and traditional degrees and credentials. A culture is beginning to form around distance learning for people who are looking to social connections enjoyed on traditional campuses. For example, students may create study groups, meetups and movements such as UnCollege.
 What do open education sources never offer?

A widely publicised example of institutionalised sexual slavery are "comfort women", a euphemism for the 200,000 women, mostly from Korea and China, who served in the Japanese army's camps during World War II. Some 35 Dutch comfort women brought a successful case before the Batavia Military Tribunal in 1948. In 1993, Chief Cabinet Secretary Yohei Kono said that women were coerced into brothels run by Japan's wartime military. Other Japanese leaders have apologized, including former Prime Minister Junichiro Koizumi in 2001. In 2007, then-Prime Minister Shinzō Abe claimed: "The fact is, there is no evidence to prove there was coercion."
In 2001 which Japanese Prime <Minister apologized for the brothels.
A: Junichiro Koizumi


Context and question: First recognized in 1900 by Max Planck, it was originally the proportionality constant between the minimal increment of energy, E, of a hypothetical electrically charged oscillator in a cavity that contained black body radiation, and the frequency, f, of its associated electromagnetic wave. In 1905 the value E, the minimal energy increment of a hypothetical oscillator, was theoretically associated by Einstein with a "quantum" or minimal element of the energy of the electromagnetic wave itself. The light quantum behaved in some respects as an electrically neutral particle, as opposed to an electromagnetic wave. It was eventually called the photon.
What is the simple name given to the dark quantum today?
Answer: unanswerable


Question: Spielberg next directed the historical drama film Lincoln, starring Daniel Day-Lewis as United States President Abraham Lincoln and Sally Field as Mary Todd Lincoln.

In December 2009, campaigners in the UK called on two leading high street retailers to stop selling clothes made with cotton which may have been picked by children. Anti-Slavery International and the Environmental Justice Foundation (EJF) accused H&M and Zara of using cotton suppliers in Bangladesh. It is also suspected that many of their raw materials originates from Uzbekistan, where children aged 10 are forced to work in the fields. The activists were calling to ban the use of Uzbek cotton and implement a "track and trace" systems to guarantee an ethical responsible source of the material.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What are activists trying to get implemented?
Ah, so..
"track and trace" systems
