Problem: Constantius, renewing his previous policies favoring the Arians, banished Athanasius from Alexandria once again. This was followed, in 356, by an attempt to arrest Athanasius during a vigil service. Athanasius fled to Upper Egypt, where he stayed in several monasteries and other houses. During this period, Athanasius completed his work Four Orations against the Arians and defended his own recent conduct in the Apology to Constantius and Apology for His Flight. Constantius's persistence in his opposition to Athanasius, combined with reports Athanasius received about the persecution of non-Arians by the new Arian bishop George of Laodicea, prompted Athanasius to write his more emotional History of the Arians, in which he described Constantius as a precursor of the Antichrist.
What did he write during this time?
The answer is the following: Four Orations against the Arians

Problem: Birds sometimes use plumage to assess and assert social dominance, to display breeding condition in sexually selected species, or to make threatening displays, as in the sunbittern's mimicry of a large predator to ward off hawks and protect young chicks. Variation in plumage also allows for the identification of birds, particularly between species. Visual communication among birds may also involve ritualised displays, which have developed from non-signalling actions such as preening, the adjustments of feather position, pecking, or other behaviour. These displays may signal aggression or submission or may contribute to the formation of pair-bonds. The most elaborate displays occur during courtship, where "dances" are often formed from complex combinations of many possible component movements; males' breeding success may depend on the quality of such displays.
Visual communication among birds may involve what kind of displays?
The answer is the following: ritualised displays

Problem: The German rocket center in Peenemünde was located in the eastern part of Germany, which became the Soviet zone of occupation. On Stalin's orders, the Soviet Union sent its best rocket engineers to this region to see what they could salvage for future weapons systems. The Soviet rocket engineers were led by Sergei Korolev. He had been involved in space clubs and early Soviet rocket design in the 1930s, but was arrested in 1938 during Joseph Stalin's Great Purge and imprisoned for six years in Siberia. After the war, he became the USSR's chief rocket and spacecraft engineer, essentially the Soviet counterpart to von Braun. His identity was kept a state secret throughout the Cold War, and he was identified publicly only as "the Chief Designer." In the West, his name was only officially revealed when he died in 1966.
What was his "secret" title after World War II?
The answer is the following: the Chief Designer

Problem: Much of mandolin development revolved around the soundboard (the top). Pre-mandolin instruments were quiet instruments, strung with as many as six courses of gut strings, and were plucked with the fingers or with a quill. However, modern instruments are louder—using four courses of metal strings, which exert more pressure than the gut strings. The modern soundboard is designed to withstand the pressure of metal strings that would break earlier instruments. The soundboard comes in many shapes—but generally round or teardrop-shaped, sometimes with scrolls or other projections. There is usually one or more sound holes in the soundboard, either round, oval, or shaped like a calligraphic F (f-hole). A round or oval sound hole may be covered or bordered with decorative rosettes or purfling.
Were premandolins quiet or loud instruments? 
The answer is the following:
quiet instruments
