Input: Pain
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)

What did Melzack and Casey theorize could influence the perception of the magnitude of pain?
Output: cognitive activities

Input: Hard rock
By the end of the decade a distinct genre of hard rock was emerging with bands like Led Zeppelin, who mixed the music of early rock bands with a more hard-edged form of blues rock and acid rock on their first two albums Led Zeppelin (1969) and Led Zeppelin II (1969), and Deep Purple, who began as a progressive rock group but achieved their commercial breakthrough with their fourth and distinctively heavier album, In Rock (1970). Also significant was Black Sabbath's Paranoid (1970), which combined guitar riffs with dissonance and more explicit references to the occult and elements of Gothic horror. All three of these bands have been seen as pivotal in the development of heavy metal, but where metal further accentuated the intensity of the music, with bands like Judas Priest following Sabbath's lead into territory that was often "darker and more menacing", hard rock tended to continue to remain the more exuberant, good-time music.

What was the title of Deep Purple's hard rock 1970 album?
Output: In Rock

Input: Kanye West
West demonstrated an affinity for the arts at an early age; he began writing poetry when he was five years old. His mother recalled that she first took notice of West's passion for drawing and music when he was in the third grade. Growing up in the city,[which?] West became deeply involved in its hip hop scene. He started rapping in the third grade and began making musical compositions in the seventh grade, eventually selling them to other artists. At age thirteen, West wrote a rap song called "Green Eggs and Ham" and began to persuade his mother to pay $25 an hour for time in a recording studio. It was a small, crude basement studio where a microphone hung from the ceiling by a wire clothes hanger. Although this wasn't what West's mother wanted, she nonetheless supported him. West crossed paths with producer/DJ No I.D., with whom he quickly formed a close friendship. No I.D. soon became West's mentor, and it was from him that West learned how to sample and program beats after he received his first sampler at age 15.

What was Kanye creating when he was five?
Output: poetry

Input: Solar energy
Shuman built the world’s first solar thermal power station in Maadi, Egypt, between 1912 and 1913. Shuman’s plant used parabolic troughs to power a 45–52 kilowatts (60–70 hp) engine that pumped more than 22,000 litres (4,800 imp gal; 5,800 US gal) of water per minute from the Nile River to adjacent cotton fields. Although the outbreak of World War I and the discovery of cheap oil in the 1930s discouraged the advancement of solar energy, Shuman’s vision and basic design were resurrected in the 1970s with a new wave of interest in solar thermal energy. In 1916 Shuman was quoted in the media advocating solar energy's utilization, saying:

From what river did the engine pump water?
Output:
Nile River
