Q: I have a new situation: Two neighboring villages practiced extensive agriculture for their food supply. Leaf village used the intentional cultivation of arthropods to help them get better harvests. Tree village didn't do that, they used conventional methods of growing their crops and got smaller harvests but used arthropods for food. But I can use this 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. What is an answer for this question: Which village didn't observe the contribution of arthropods to human food supply?
A: Tree

Q: I have a new situation: Helen got lots of different fruit as a gift from a friend that owned an orchard. She received apples, pears, apricots, peaches, plums, quince, among others. She decided to candy apples, apricots, and pears, and to keep the others fresh for as long as possible. But I can use this background: Candied fruit, also known as crystallized fruit or glace fruit, has existed since the 14th century. Whole fruit, smaller pieces of fruit, or pieces of peel, are placed in heated sugar syrup, which absorbs the moisture from within the fruit and eventually preserves it. Depending on size and type of fruit, this process of preservation can take from several days to several months.[1] This process allows the fruit to retain its quality for a year.[2] The continual process of drenching the fruit in syrup causes the fruit to become saturated with sugar, preventing the growth of spoilage microorganisms due to the unfavourable osmotic pressure this creates.[3] What is an answer for this question: Which fruit lasted longer, pears or plums?
A: pears

Q: I have a new situation: Deep lake presents geothermal activity, while Shallow lake has mixing of saline water with fresh water. Deep lake had more instances of divers having problems because of thermoclines. But I can use this background: Thermoclines, or sudden changes in temperature. Where the air temperature is higher than the water temperature, shallow water may be warmed by the air and the sunlight but deeper water remains cold resulting in a lowering of temperature as the diver descends. This temperature change may be concentrated over a small vertical interval, when it is called a thermocline.[3][4] Where cold, fresh water enters a warmer sea the fresh water may float over the denser saline water, so the temperature rises as the diver descends.[3] In lakes exposed to geothermal activity, the temperature of the deeper water may be warmer than the surface water. This will usually lead to convection currents.[3] What is an answer for this question: Which lake has less geothermal activity?
A: Shallow lake

Q: I have a new situation: Two competing countries used different energy sources to produce their electricity. Turkey used mostly fossil fuels, while Greece used nuclear power. But I can use this background: In the U.S., the majority of electricity is produced by burning coal or other fossil fuels. This causes air pollution that harms the health of living things. The air pollution also causes acid rain and contributes to global warming. In addition, fossil fuels are nonrenewable resources, so if we keep using them, they will eventually run out. The main advantage of nuclear energy is that it doesn't release air pollution or cause the other environmental problems associated with the burning of fossil fuels. On the other other hand, radioactive elements are nonrenewable like fossil fuels and could eventually be used up. What is an answer for this question: Which country caused less air pollution?
A:
Greece
