The higher-level phylogeny of the arthropods continues to be a matter of debate and research. In 2008, researchers at Tufts University uncovered what they believe is the world's oldest known full-body impression of a primitive flying insect, a 300 million-year-old specimen from the Carboniferous period. The oldest definitive insect fossil is the Devonian Rhyniognatha hirsti, from the 396-million-year-old Rhynie chert. It may have superficially resembled a modern-day silverfish insect. This species already possessed dicondylic mandibles (two articulations in the mandible), a feature associated with winged insects, suggesting that wings may already have evolved at this time. Thus, the first insects probably appeared earlier, in the Silurian period.
From what period do researchers believe that the oldest known full-body impression of a flying insect originates?
****
The answer: Carboniferous

Han-era astronomers adopted a geocentric model of the universe, theorizing that it was shaped like a sphere surrounding the earth in the center. They assumed that the Sun, Moon, and planets were spherical and not disc-shaped. They also thought that the illumination of the Moon and planets was caused by sunlight, that lunar eclipses occurred when the Earth obstructed sunlight falling onto the Moon, and that a solar eclipse occurred when the Moon obstructed sunlight from reaching the Earth. Although others disagreed with his model, Wang Chong accurately described the water cycle of the evaporation of water into clouds.
What did astronomers believe the shape of the Sun to be during this era?
****
The answer: spherical

With regard to a safety net, Hayek advocated "some provision for those threatened by the extremes of indigence or starvation, be if only in the interest of those who require protection against acts of desperation on the part of the needy." As referenced in the section on "The economic calculation problem," Hayek wrote that "there is no reason why... the state should not help to organize a comprehensive system of social insurance." Summarizing on this topic, Wapshott writes "[Hayek] advocated mandatory universal health care and unemployment insurance, enforced, if not directly provided, by the state." Bernard Harcourt says that "Hayek was adamant about this." In the 1973 Law, Legislation, and Liberty, Hayek wrote:
Who did Hayek say should provide a safety net for society?
****
The answer: the state

Plymouth is home to the Marine Biological Association of the United Kingdom (MBA) which conducts research in all areas of the marine sciences. The Plymouth Marine Laboratory is an offshoot of the MBA. Together with the National Marine Aquarium, the Sir Alister Hardy Foundation for Ocean Sciences, Plymouth University's Marine Institute and the Diving Diseases Research Centre, these marine-related organisations form the Plymouth Marine Sciences Partnership. The Plymouth Marine Laboratory, which focuses on global issues of climate change and sustainability. It monitors the effects of ocean acidity on corals and shellfish and reports the results to the UK government. It also cultivates algae that could be used to make biofuels or in the treatment of waste water by using technology such as photo-bioreactors. It works alongside the Boots Group to investigate the use of algae in skin care protects, taking advantage of the chemicals they contain that adapt to protect themselves from the sun.
What organization known as the MBA is based in Plymouth?
****
The answer:
Marine Biological Association
