Problem: Oklahoma:

Because of Oklahoma's position between zones of differing prevailing temperature and winds, weather patterns within the state can vary widely over relatively short distances and can change drastically in a short time. As an example, on November 11, 1911, the temperature at Oklahoma City reached 83 °F (28 °C) in the afternoon (the record high for that date), then an Arctic cold front of unprecedented intensity slammed across the state, causing the temperature to crash 66 degrees, down to 17 °F (−8 °C) at midnight (the record low for that date); thus, both the record high and record low for November 11 were set on the same date. This type of phenomenon is also responsible for many of the tornadoes in the area, such as the 1912 Oklahoma tornado outbreak, when a warm front traveled along a stalled cold front, resulting in an average of about one tornado per hour over the course of a day.

How fast did the 1912 tornado outbreak make tornadoes?
---
A: one tornado per hour


Problem: In the subtractive color system, used in painting and color printing, green is created by a combination of yellow and blue, or yellow and cyan; in the RGB color model, used on television and computer screens, it is one of the additive primary colors, along with red and blue, which are mixed in different combinations to create all other colors. On the HSV color wheel, also known as the RGB color wheel, the complement of green is magenta; that is, a color corresponding to an equal mixture of red and blue light (one of the purples). On a traditional color wheel, based on subtractive color, the complementary color to green is considered to be red.
What is the complementary color to blue?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The Slavs under name of the Antes and the Sclaveni make their first appearance in Byzantine records in the early 6th century. Byzantine historiographers under Justinian I (527–565), such as Procopius of Caesarea, Jordanes and Theophylact Simocatta describe tribes of these names emerging from the area of the Carpathian Mountains, the lower Danube and the Black Sea, invading the Danubian provinces of the Eastern Empire.
Tribes of Slavs were invading what provinces of the Eastern Empire?
A: the Danubian provinces


Context and question: Many sports popular today were formalised by British Public schools and universities in the 19th century. These schools produced the civil servants and military and naval officers required to build and maintain the British empire, and team sports were considered a vital tool for training their students to think and act as part of a team. Former public schoolboys continued to pursue these activities, and founded organisations such as the Football Association (FA). Today's association of football with the working classes began in 1885 when the FA changed its rules to allow professional players.
Who founded organizations like the FA?
Answer: Former public schoolboys


Question: 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.
Is there an answer to this question: Whose principles did L. Bol imitate?

Answer: unanswerable


The Logic and Metaphysics have been extensively reprinted, the latter, e.g., at Venice in 1493, 1495, and 1546. Some of his shorter essays on medicine, logic, etc., take a poetical form (the poem on logic was published by Schmoelders in 1836).[citation needed] Two encyclopaedic treatises, dealing with philosophy, are often mentioned. The larger, Al-Shifa' (Sanatio), exists nearly complete in manuscript in the Bodleian Library and elsewhere; part of it on the De Anima appeared at Pavia (1490) as the Liber Sextus Naturalium, and the long account of Ibn Sina's philosophy given by Muhammad al-Shahrastani seems to be mainly an analysis, and in many places a reproduction, of the Al-Shifa'. A shorter form of the work is known as the An-najat (Liberatio). The Latin editions of part of these works have been modified by the corrections which the monastic editors confess that they applied. There is also a حكمت مشرقيه (hikmat-al-mashriqqiyya, in Latin Philosophia Orientalis), mentioned by Roger Bacon, the majority of which is lost in antiquity, which according to Averroes was pantheistic in tone.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who published Avicenna's song on logic?
Ah, so..
unanswerable
