Input: Read this: Colour broadcasts started at similarly higher resolutions, first with the US NTSC color system in 1953, which was compatible with the earlier monochrome systems and therefore had the same 525 lines of resolution. European standards did not follow until the 1960s, when the PAL and SECAM color systems were added to the monochrome 625 line broadcasts.
Question:  The PAL and SECAM were black and white systems where?

Output: unanswerable


QUES: In 1968 Ronald Melzack and Kenneth Casey described pain in terms of its three dimensions: "sensory-discriminative" (sense of the intensity, location, quality and duration of the pain), "affective-motivational" (unpleasantness and urge to escape the unpleasantness), and "cognitive-evaluative" (cognitions such as appraisal, cultural values, distraction and hypnotic suggestion). They theorized that pain intensity (the sensory discriminative dimension) and unpleasantness (the affective-motivational dimension) are not simply determined by the magnitude of the painful stimulus, but "higher" cognitive activities can influence perceived intensity and unpleasantness. Cognitive activities "may affect both sensory and affective experience or they may modify primarily the affective-motivational dimension. Thus, excitement in games or war appears to block both dimensions of pain, while suggestion and placebos may modulate the affective-motivational dimension and leave the sensory-discriminative dimension relatively undisturbed." (p. 432) The paper ends with a call to action: "Pain can be treated not only by trying to cut down the sensory input by anesthetic block, surgical intervention and the like, but also by influencing the motivational-affective and cognitive factors as well." (p. 435)

QUES: In June 1854, the Allied expeditionary force landed at Varna, a city on the Black Sea's western coast (now in Bulgaria). They made little advance from their base there.:175–176 In July 1854, the Turks under Omar Pasha crossed the Danube into Wallachia and on 7 July 1854, engaged the Russians in the city of Giurgiu and conquered it. The capture of Giurgiu by the Turks immediately threatened Bucharest in Wallachia with capture by the same Turk army. On 26 July 1854, Tsar Nicholas I ordered the withdrawal of Russian troops from the Principalities. Also, in late July 1854, following up on the Russian retreat, the French staged an expedition against the Russian forces still in Dobruja, but this was a failure.:188–190
In what year did the Turks cross the Danube into Wallachia ?

ANS: 1854


Oklahoma had 598 incorporated places in 2010, including four cities over 100,000 in population and 43 over 10,000. Two of the fifty largest cities in the United States are located in Oklahoma, Oklahoma City and Tulsa, and 65 percent of Oklahomans live within their metropolitan areas, or spheres of economic and social influence defined by the United States Census Bureau as a metropolitan statistical area. Oklahoma City, the state's capital and largest city, had the largest metropolitan area in the state in 2010, with 1,252,987 people, and the metropolitan area of Tulsa had 937,478 residents. Between 2000 and 2010, the cities that led the state in population growth were Blanchard (172.4%), Elgin (78.2%), Jenks (77.0%), Piedmont (56.7%), Bixby (56.6%), and Owasso (56.3%).
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How many incorporated cities are in Oklahoma?

Context and question: In signal processing, data compression, source coding, or bit-rate reduction involves encoding information using fewer bits than the original representation. Compression can be either lossy or lossless. Lossless compression reduces bits by identifying and eliminating statistical redundancy. No information is lost in lossless compression. Lossy compression reduces bits by identifying unnecessary information and removing it. The process of reducing the size of a data file is referred to as data compression. In the context of data transmission, it is called source coding (encoding done at the source of the data before it is stored or transmitted) in opposition to channel coding.
What involves encoding information using fewer bits than the channel coding?
