Question: BYU has designated energy conservation, products and materials, recycling, site planning and building design, student involvement, transportation, water conservation, and zero waste events as top priority categories in which to further its efforts to be an environmentally sustainable campus. The university has stated that "we have a responsibility to be wise stewards of the earth and its resources." BYU is working to increase the energy efficiency of its buildings by installing various speed drives on all pumps and fans, replacing incandescent lighting with fluorescent lighting, retrofitting campus buildings with low-E reflective glass, and upgraded roof insulation to prevent heat loss. The student groups BYU Recycles, Eco-Response, and BYU Earth educate students, faculty, staff, and administrators about how the campus can decrease its environmental impact. BYU Recycles spearheaded the recent campaign to begin recycling plastics, which the university did after a year of student campaigning.

Question: The adolescent growth spurt is a rapid increase in the individual's height and weight during puberty resulting from the simultaneous release of growth hormones, thyroid hormones, and androgens. Males experience their growth spurt about two years later, on average, than females. During their peak height velocity (the time of most rapid growth), adolescents grow at a growth rate nearly identical to that of a toddler—about 4 inches (10.3 cm) a year for males and 3.5 inches (9 cm) for females. In addition to changes in height, adolescents also experience a significant increase in weight (Marshall, 1978). The weight gained during adolescence constitutes nearly half of one's adult body weight. Teenage and early adult males may continue to gain natural muscle growth even after puberty.
Try to answer this question if possible: How much later on average do males experience their growth spurt?
Answer: two years later
Question: Changes also took place within the recruitment and composition of armies. The use of the national or feudal levy was gradually replaced by paid troops of domestic retinues or foreign mercenaries. The practice was associated with Edward III of England and the condottieri of the Italian city-states. All over Europe, Swiss soldiers were in particularly high demand. At the same time, the period also saw the emergence of the first permanent armies. It was in Valois France, under the heavy demands of the Hundred Years' War, that the armed forces gradually assumed a permanent nature.
