QUES: Near-infrared is the region closest in wavelength to the radiation detectable by the human eye, mid- and far-infrared are progressively further from the visible spectrum. Other definitions follow different physical mechanisms (emission peaks, vs. bands, water absorption) and the newest follow technical reasons (the common silicon detectors are sensitive to about 1,050 nm, while InGaAs's sensitivity starts around 950 nm and ends between 1,700 and 2,600 nm, depending on the specific configuration). Unfortunately, international standards for these specifications are not currently available.
What InGaAs is progressively further from the visible spectrum for the human eye?

ANS: 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)
What did Melzack and Casey theorize could influence the perception of the magnitude of pain?

ANS: cognitive activities

QUES: The National History Museum of Montevideo is located in the historical residence of General Fructuoso Rivera. It exhibits artifacts related to the history of Uruguay. In a process begun in 1998, the National Museum of Natural History (1837) and the National Museum of Anthropology (1981), merged in 2001, becoming the National Museum of Natural History and Anthropology. In July 2009, the two institutions again became independent. The Historical Museum has annexed eight historical houses in the city, five of which are located in the Ciudad Vieja. One of them, on the same block with the main building, is the historic residence of Antonio Montero, which houses the Museo Romantico.
The National History Museum of Montevideo is located where?

ANS: the historical residence of General Fructuoso Rivera

QUES: Multiracial people who wanted to acknowledge their full heritage won a victory of sorts in 1997, when the Office of Management and Budget (OMB) changed the federal regulation of racial categories to permit multiple responses. This resulted in a change to the 2000 United States Census, which allowed participants to select more than one of the six available categories, which were, in brief: "White," "Black or African American," "Asian," "American Indian or Alaskan Native," "Native Hawaiian or other Pacific Islander," and "Other." Further details are given in the article: Race (U.S. census). The OMB made its directive mandatory for all government forms by 2003.
In what year were participants no longer allowed to choose more than one of the six available categories?
