Problem: The first polytechnic in Hong Kong is The Hong Kong Polytechnic, established in 1972 through upgrading the Hong Kong Technical College (Government Trade School before 1947). The second polytechnic, the City Polytechnic of Hong Kong, was founded in 1984. These polytechnics awards diplomas, higher diplomas, as well as academic degrees. Like the United Kingdom, the two polytechnics were granted university status in 1994, and renamed The Hong Kong Polytechnic University and the City University of Hong Kong respectively. The Hong Kong University of Science and Technology, a university with a focus in applied science, engineering and business, was founded in 1991.
What Hong Kong university was created in 1991?
The answer is the following: Hong Kong University of Science and Technology

Problem: Whitehall's disquiet at the failures of the RAF led to the replacement of Dowding (who was already due for retirement) with Sholto Douglas on 25 November. Douglas set about introducing more squadrons and dispersing the few GL sets to create a carpet effect in the southern counties. Still, in February 1941, there remained only seven squadrons with 87 pilots, under half the required strength. The GL carpet was supported by six GCI sets controlling radar-equipped night-fighters. By the height of the Blitz, they were becoming more successful. The number of contacts and combats rose in 1941, from 44 and two in 48 sorties in January 1941, to 204 and 74 in May (643 sorties). But even in May, 67% of the sorties were visual cat's-eye missions. Curiously, while 43% of the contacts in May 1941 were by visual sightings, they accounted for 61% of the combats. Yet when compared with Luftwaffe daylight operations, there was a sharp decline in German losses to 1%. If a vigilant bomber crew could spot the fighter first, they had a decent chance at evading it.
What supported the GL carpet?
The answer is the following: six GCI sets controlling radar-equipped night-fighters

Problem: In Eastern Europe, Byzantium revived its fortunes under Emperor Basil I (r. 867–886) and his successors Leo VI (r. 886–912) and Constantine VII (r. 913–959), members of the Macedonian dynasty. Commerce revived and the emperors oversaw the extension of a uniform administration to all the provinces. The military was reorganised, which allowed the emperors John I (r. 969–976) and Basil II (r. 976–1025) to expand the frontiers of the empire on all fronts. The imperial court was the centre of a revival of classical learning, a process known as the Macedonian Renaissance. Writers such as John Geometres (fl. early 10th century) composed new hymns, poems, and other works. Missionary efforts by both eastern and western clergy resulted in the conversion of the Moravians, Bulgars, Bohemians, Poles, Magyars, and Slavic inhabitants of the Kievan Rus'. These conversions contributed to the founding of political states in the lands of those peoples—the states of Moravia, Bulgaria, Bohemia, Poland, Hungary, and the Kievan Rus'. Bulgaria, which was founded around 680, at its height reached from Budapest to the Black Sea and from the Dnieper River in modern Ukraine to the Adriatic Sea. By 1018, the last Bulgarian nobles had surrendered to the Byzantine Empire.
During what period did Constantine VII reign?
The answer is the following: 913–959

Problem: The life cycles of insects vary but most hatch from eggs. Insect growth is constrained by the inelastic exoskeleton and development involves a series of molts. The immature stages can differ from the adults in structure, habit and habitat, and can include a passive pupal stage in those groups that undergo 4-stage metamorphosis (see holometabolism). Insects that undergo 3-stage metamorphosis lack a pupal stage and adults develop through a series of nymphal stages. The higher level relationship of the Hexapoda is unclear. Fossilized insects of enormous size have been found from the Paleozoic Era, including giant dragonflies with wingspans of 55 to 70 cm (22–28 in). The most diverse insect groups appear to have coevolved with flowering plants.
What stage of development differentiates a 4-stage metamorphosis from a 3-stage metamorphosis, notably absent in the latter?
The answer is the following:
pupal stage
