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: 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 naive 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 naive 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: Which happened earlier, the trio began playing together or the Cubs won the pennant four times between 1906 and 1910?, Context: "Baseball's Sad Lexicon," also known as "Tinker to Evers to Chance" after its refrain, is a 1910 baseball poem by Franklin Pierce Adams. The poem is presented as a single, rueful stanza from the point of view of a New York Giants fan seeing the talented Chicago Cubs infield of shortstop Joe Tinker, second baseman Johnny Evers, and first baseman Frank Chance complete a double play. The trio began playing together with the Cubs in 1902, and formed a double play combination that lasted through April 1912. The Cubs won the pennant four times between 1906 and 1910, often defeating the Giants en route to the World Series.
Example Output: The trio began playing together

Example Input: Who is Mali government having issues with besides Tuaregs?, Context: Although Mali has enjoyed a reasonably good inter-ethnic relationships based on the long history of coexistence, some hereditary servitude and bondage relationship exist, as well as ethnic tension between settled Songhai and nomadic Tuaregs of the north. Due to a backlash against the northern population after independence, Mali is now in a situation where both groups complain about discrimination on the part of the other group. This conflict also plays a role in the continuing Northern Mali conflict where there is a tension between both Tuaregs and the Malian government, and the Tuaregs and radical Islamists who are trying to establish sharia law.
Example Output:
radical Islamists
