Question: 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.
Is there an answer to this question: What caused Oklahoma's temperature to plummet 66 degrees on Nov 11, 1911?

Answer: an Arctic cold front


Question: The budget of the city for 2013 was €7.6 billion, of which 5.4 billion went for city administration, while €2.2 billion went for investment. The largest part of the budget (38 percent) went for public housing and urbanism projects; 15 percent for roads and transport; 8 percent for schools (which are mostly financed by the state budget); 5 percent for parks and gardens; and 4 percent for culture. The main source of income for the city is direct taxes (35 percent), supplemented by a 13-percent real estate tax; 19 percent of the budget comes in a transfer from the national government.
Is there an answer to this question: What percent of the budget goes towards public housing and urbanism projects?

Answer: 38


Question: where  is the maximum possible exposure that does not lead to a clipped or bloomed camera output. Typically, the lower limit of the saturation speed is determined by the sensor itself, but with the gain of the amplifier between the sensor and the analog-to-digital converter, the saturation speed can be increased. The factor 78 is chosen such that exposure settings based on a standard light meter and an 18-percent reflective surface will result in an image with a grey level of 18%/√2 = 12.7% of saturation. The factor √2 indicates that there is half a stop of headroom to deal with specular reflections that would appear brighter than a 100% reflecting white surface.
Is there an answer to this question: A grey level of 12.7 results in what saturation?

Answer: unanswerable


Question: Surveys show that red is the color most associated with courage. In western countries red is a symbol of martyrs and sacrifice, particularly because of its association with blood. Beginning in the Middle Ages, the Pope and Cardinals of the Roman Catholic Church wore red to symbolize the blood of Christ and the Christian martyrs. The banner of the Christian soldiers in the First Crusade was a red cross on a white field, the St. George's Cross. According to Christian tradition, Saint George was a Roman soldier who was a member of the guards of the Emperor Diocletian, who refused to renounce his Christian faith and was martyred. The Saint George's Cross became the Flag of England in the 16th century, and now is part of the Union Flag of the United Kingdom, as well as the Flag of the Republic of Georgia.
Is there an answer to this question: Who was Saint George believed to be?

Answer:
a Roman soldier
