Input: Read this: Beyoncé's vocal range spans four octaves. Jody Rosen highlights her tone and timbre as particularly distinctive, describing her voice as "one of the most compelling instruments in popular music". While another critic says she is a "Vocal acrobat, being able to sing long and complex melismas and vocal runs effortlessly, and in key. Her vocal abilities mean she is identified as the centerpiece of Destiny's Child. The Daily Mail calls Beyoncé's voice "versatile", capable of exploring power ballads, soul, rock belting, operatic flourishes, and hip hop. Jon Pareles of The New York Times commented that her voice is "velvety yet tart, with an insistent flutter and reserves of soul belting". Rosen notes that the hip hop era highly influenced Beyoncé's strange rhythmic vocal style, but also finds her quite traditionalist in her use of balladry, gospel and falsetto. Other critics praise her range and power, with Chris Richards of The Washington Post saying she was "capable of punctuating any beat with goose-bump-inducing whispers or full-bore diva-roars."
Question: Beyonce's range in singing is how many octaves?

Input: Read this: At her Silver Jubilee in 1977, the crowds and celebrations were genuinely enthusiastic, but in the 1980s, public criticism of the royal family increased, as the personal and working lives of Elizabeth's children came under media scrutiny. Elizabeth's popularity sank to a low point in the 1990s. Under pressure from public opinion, she began to pay income tax for the first time, and Buckingham Palace was opened to the public. Discontent with the monarchy reached its peak on the death of Diana, Princess of Wales, though Elizabeth's personal popularity and support for the monarchy rebounded after her live television broadcast to the world five days after Diana's death.
Question: What attribute of Elizabeth fell to  low in the 1990s?

Output: popularity


Input: Read this: Based on discoveries made through neural mapping of the limbic system, the neurobiological explanation of human emotion is that emotion is a pleasant or unpleasant mental state organized in the limbic system of the mammalian brain. If distinguished from reactive responses of reptiles, emotions would then be mammalian elaborations of general vertebrate arousal patterns, in which neurochemicals (for example, dopamine, noradrenaline, and serotonin) step-up or step-down the brain's activity level, as visible in body movements, gestures and postures. Emotions can likely be mediated by pheromones (see fear).
Question: What system was examined to develop the neurobiological explanation of human emotion?

Output: limbic


Input: Read this: Emotions involve different components, such as subjective experience, cognitive processes, expressive behavior, psychophysiological changes, and instrumental behavior. At one time, academics attempted to identify the emotion with one of the components: William James with a subjective experience, behaviorists with instrumental behavior, psychophysiologists with physiological changes, and so on. More recently, emotion is said to consist of all the components. The different components of emotion are categorized somewhat differently depending on the academic discipline. In psychology and philosophy, emotion typically includes a subjective, conscious experience characterized primarily by psychophysiological expressions, biological reactions, and mental states. A similar multicomponential description of emotion is found in sociology. For example, Peggy Thoits described emotions as involving physiological components, cultural or emotional labels (e.g., anger, surprise etc.), expressive body actions, and the appraisal of situations and contexts.
Question: Along with subjective experience, cognitive processes, expressive behavior and psychophysiological changes, what is another notable unemotional component?
