In this task, you are given a question and a context passage. You have to answer the question based on the given passage.

Example Input: Why were 78s more popular than 45s in 1954-55?, Context: Some of Elvis Presley's early singles on Sun Records might have sold more copies on 78 than on 45. This is because the majority of those sales in 1954–55 were to the "hillbilly" market in the South and Southwestern United States, where replacing the family 78 rpm player with a new 45 rpm player was a luxury few could afford at the time. By the end of 1957, RCA Victor announced that 78s accounted for less than 10% of Presley's singles sales, essentially announcing the death throes of the 78 rpm format. The last Presley single released on 78 in the United States was RCA Victor 20-7410, I Got Stung/One Night (1958), while the last 78 in the UK was RCA 1194, A Mess Of Blues/Girl Of My Best Friend (1960).
Example Output: replacing the family 78 rpm player with a new 45 rpm player was a luxury few could afford

Example Input: What needs to decrease before pituitary growth hormone can increase in the blood?, Context: In addition to the negative consequences of sleep deprivation, sleep and the intertwined circadian system have been shown to have strong regulatory effects on immunological functions affecting both the innate and the adaptive immunity. First, during the early slow-wave-sleep stage, a sudden drop in blood levels of cortisol, epinephrine, and norepinephrine induce increased blood levels of the hormones leptin, pituitary growth hormone, and prolactin. These signals induce a pro-inflammatory state through the production of the pro-inflammatory cytokines interleukin-1, interleukin-12, TNF-alpha and IFN-gamma. These cytokines then stimulate immune functions such as immune cells activation, proliferation, and differentiation. It is during this time that undifferentiated, or less differentiated, like naïve and central memory T cells, peak (i.e. during a time of a slowly evolving adaptive immune response). In addition to these effects, the milieu of hormones produced at this time (leptin, pituitary growth hormone, and prolactin) support the interactions between APCs and T-cells, a shift of the Th1/Th2 cytokine balance towards one that supports Th1, an increase in overall Th cell proliferation, and naïve T cell migration to lymph nodes. This milieu is also thought to support the formation of long-lasting immune memory through the initiation of Th1 immune responses.
Example Output: cortisol, epinephrine, and norepinephrine

Example Input: What religion is prevalent in Myanmar?, Context: A diverse range of indigenous cultures exist in Myanmar, the majority culture is primarily Buddhist and Bamar. Bamar culture has been influenced by the cultures of neighbouring countries. This is manifested in its language, cuisine, music, dance and theatre. The arts, particularly literature, have historically been influenced by the local form of Theravada Buddhism. Considered the national epic of Myanmar, the Yama Zatdaw, an adaptation of India's Ramayana, has been influenced greatly by Thai, Mon, and Indian versions of the play. Buddhism is practised along with nat worship, which involves elaborate rituals to propitiate one from a pantheon of 37 nats.
Example Output:
Buddhism is practised along with nat worship
