Problem: Separation of church and state in the United States:

On December 20, 2005, the United States Court of Appeals for the Sixth Circuit ruled in the case of ACLU v. Mercer County that the continued display of the Ten Commandments as part of a larger display on American legal traditions in a Kentucky courthouse was allowed, because the purpose of the display (educating the public on American legal traditions) was secular in nature. In ruling on the Mount Soledad cross controversy on May 3, 2006, however, a federal judge ruled that the cross on public property on Mount Soledad must be removed.

When was a ruling handed down on the Mount Soledad cross controversy?

A: May 3, 2006


Problem: Valencia stands on the banks of the Turia River, located on the eastern coast of the Iberian Peninsula and the western part of the Mediterranean Sea, fronting the Gulf of Valencia. At its founding by the Romans, it stood on a river island in the Turia, 6.4 km (4 mi) from the sea. The Albufera, a freshwater lagoon and estuary about 11 km (7 mi) south of the city, is one of the largest lakes in Spain. The City Council bought the lake from the Crown of Spain for 1,072,980 pesetas in 1911, and today it forms the main portion of the Parc Natural de l'Albufera (Albufera Nature Reserve), with a surface area of 21,120 hectares (52,200 acres). In 1986, because of its cultural, historical, and ecological value, the Generalitat Valenciana declared it a natural park.
From what entity was the Albufera bought?

Answer: Crown of Spain


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The cottonseed which remains after the cotton is ginned is used to produce cottonseed oil, which, after refining, can be consumed by humans like any other vegetable oil. The cottonseed meal that is left generally is fed to ruminant livestock; the gossypol remaining in the meal is toxic to monogastric animals. Cottonseed hulls can be added to dairy cattle rations for roughage. During the American slavery period, cotton root bark was used in folk remedies as an abortifacient, that is, to induce a miscarriage. Gossypol was one of the many substances found in all parts of the cotton plant and it was described by the scientists as 'poisonous pigment'. It also appears to inhibit the development of sperm or even restrict the mobility of the sperm. Also, it is thought to interfere with the menstrual cycle by restricting the release of certain hormones.
For what is cottonseed used after it is separate from root bark?
A: unanswerable


Context and question: Meanwhile, he had written to Abu Ya'far, the prefect of the dynamic city of Isfahan, offering his services. The new emir of Hamadan, hearing of this correspondence and discovering where Ibn Sina was hiding, incarcerated him in a fortress.

After a perilous journey, they reached Isfahan, receiving an honorable welcome from the prince.

Question: Arsenal Football Club was formed as Dial Square in 1886 by workers at the Royal Arsenal in Woolwich, south-east London, and were renamed Royal Arsenal shortly afterwards. The club was renamed again to Woolwich Arsenal after becoming a limited company in 1893. The club became the first southern member of the Football League in 1893, starting out in the Second Division, and won promotion to the First Division in 1904. The club's relative geographic isolation resulted in lower attendances than those of other clubs, which led to the club becoming mired in financial problems and effectively bankrupt by 1910, when they were taken over by businessmen Henry Norris and William Hall. Norris sought to move the club elsewhere, and in 1913, soon after relegation back to the Second Division, Arsenal moved to the new Arsenal Stadium in Highbury, north London; they dropped "Woolwich" from their name the following year. Arsenal only finished in fifth place in the second division during the last pre-war competitive season of 1914–15, but were nevertheless elected to rejoin the First Division when competitive football resumed in 1919–20, at the expense of local rivals Tottenham Hotspur. Some books have reported that this election to division 1 was achieved by dubious means.
Is there an answer to this question: In what year were the Tottenham Hotspur formed?

Answer: unanswerable


Question: The early Qing military was rooted in the Eight Banners first developed by Nurhaci to organize Jurchen society beyond petty clan affiliations. There were eight banners in all, differentiated by color. The yellow, bordered yellow, and white banners were known as the "Upper Three Banners" and were under the direct command of the emperor. Only Manchus belonging to the Upper Three Banners, and selected Han Chinese who had passed the highest level of martial exams could serve as the emperor's personal bodyguards. The remaining Banners were known as the "Lower Five Banners." They were commanded by hereditary Manchu princes descended from Nurhachi's immediate family, known informally as the "Iron cap princes". Together they formed the ruling council of the Manchu nation as well as high command of the army. Nurhachi's son Hong Taiji expanded the system to include mirrored Mongol and Han Banners. After capturing Beijing in 1644, the relatively small Banner armies were further augmented by the Green Standard Army, made up of those Ming troops who had surrendered to the Qing, which eventually outnumbered Banner troops three to one. They maintained their Ming era organization and were led by a mix of Banner and Green Standard officers.[citation needed]
Is there an answer to this question: What were the rest of the banners called?

Answer:
Lower Five Banners
