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

Which KG unit has two identical digits, 55, 26, or 54?, Context: Five nights later, Birmingham was hit by 369 bombers from KG 54, KG 26, and KG 55. By the end of November, 1,100 bombers were available for night raids. An average of 200 were able to strike per night. This weight of attack went on for two months, with the Luftwaffe dropping 13,900 short tons (12,600 t) of bombs. In November 1940, 6,000 sorties and 23 major attacks (more than 100 tons of bombs dropped) were flown. Two heavy (50 short tons (45 t) of bombs) attacks were also flown. In December, only 11 major and five heavy attacks were made.

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.

Who is moving toward secularism?, Context: In Europe, there has been a general move away from religious observance and belief in Christian teachings and a move towards secularism. The Enlightenment is largely responsible for the spread of secularism. Several scholars have argued for a link between the rise of secularism and Protestantism, attributing it to the wide-ranging freedom in the Protestant countries. In North America, South America and Australia Christian religious observance is much higher than in Europe. United States remains particularly religious in comparison to other developed countries. South America, historically Roman Catholic, has experienced a large Evangelical and Pentecostal infusion in the 20th and 21st centuries.
