[Q]: Given the background: The intentional cultivation of arthropods and other small animals for human food, referred to as minilivestock, is now emerging in animal husbandry as an ecologically sound concept. However, the greatest contribution of arthropods to human food supply is by pollination. Three-fourths of the world's flowering plants and about 35% of the world's food crops depend on animal pollinators to reproduce and increase crop yields. More than 3,500 species of native bees pollinate crops. Some scientists estimate that one out of every three bites of food we eat exists because of animal pollinators, including birds and bats and arthropods like bees, butterflies and moths, and beetles and other insects. and the situation: Two villages had many inhabitants practicing horticulture. People from Valley village grew flowers and used arthropodes and other insects for pollination and crop protection. Granite village used arthropods and snails, they cultivated them for food. Answer the following question: Which village didn't use arthropods to reproduce flowering plants?
****
[A]: Granite

[Q]: Given the background: "There is now unequivocal evidence that biodiversity loss reduces the efficiency by which ecological communities capture biologically essential resources, produce biomass, decompose and recycle biologically essential nutrients... There is mounting evidence that biodiversity increases the stability of ecosystem functions through time... Diverse communities are more productive because they contain key species that have a large influence on productivity and differences in functional traits among organisms increase total resource capture... The impacts of diversity loss on ecological processes might be sufficiently large to rival the impacts of many other global drivers of environmental change... Maintaining multiple ecosystem processes at multiple places and times requires higher levels of biodiversity than does a single process at a single place and time." and the situation: The government of Ecuador has been actively pushing to increase biodiversity. They have been quite successful in their pursuit. Moreover, the citizens of Ecuador are receptive about the idea of increased biodiversity. On the contrary, the Government of Oman was not very active in increasing the biodiversity of their country. As a result, Oman, at present, is not very biodiverse. Answer the following question: Which place would have more key species, Ecuador or Oman?
****
[A]: Ecuador

[Q]: Given the background: Allergy symptoms can range from mild to severe. Mild symptoms might include itchy eyes, sneezing, and a runny nose. Severe symptoms can cause difficulty breathing, which may be life threatening. Keep in mind that it is the immune system and not the allergen that causes the allergy symptoms. Allergy symptoms can be treated with medications such as antihistamines. Severe allergic reactions may require an injection of the hormone epinephrine. These treatments lessen or counter the immune system's response. and the situation: The doctors used used the newly discovered allergy medicine on two groups of people. As a result, group Alpha experienced only mild allergy symptoms, while group Beta started experiencing severe allergy symptoms and remained hospitalized requiring additional treatment. Answer the following question: Which group experienced more severe symptoms than a runny nose?
****
[A]: group Beta

[Q]: Given the background: Mantle melting can come about three ways: (1) when the temperature rises, (2) if the pressure lowers (which lowers the melting point), and (3) if water is added, which lowers the melting point. Two of these (1 and 3) might explain why there are volcanoes at convergent plate boundaries: the temperature of the subducting plate increases as it sinks into the hot mantle (1). Sediments lying on top of the subducting plate contain water. As the sediments subduct, the water rises into the overlying mantle material. This lowers the melting temperature of the mantle (3). When the mantle above the subducting plate melts, volcanoes form above it. This leads to volcanoes in an island arc or continental arc. and the situation: Ben and Mike both studied earthquakes, while Mike was more interested specifically in mantle melting and related phenomena. Answer the following question: Which person didn't learn that the subducting plate increases as it sinks into the hot mantle?
****
[A]:
Ben
