Question: Given the background: To determine the concentration of an acid in an aqueous solution, an acid-base titration is commonly performed. A strong base solution with a known concentration, usually NaOH or KOH, is added to neutralize the acid solution according to the color change of the indicator with the amount of base added.[7] The titration curve of an acid titrated by a base has two axes, with the base volume on the x-axis and the solution's pH value on the y-axis. The pH of the solution always goes up as the base is added to the solution. and the situation: Due to increased carbon dioxide in the atmosphere more an more carbon dioxide is mixing with ocean water - thus increasing the acidity of the world's oceans. Rob is a climate scientist. He is measuring the acidity of the Atlantic ocean and the Pacific Ocean. To determine ocean water acidity he performed an acid-base titration. His conclusion is that Atlantic Ocean's acidity reached higher level than Pacific Ocean's acidity. Answer the following question: In which ocean's acidity test the PH of the solution would be higher as a result of amount of added base, Atlantic Ocean or Pacific Ocean?
Answer: Atlantic Ocean

[Q]: Given the background: In the long term, the greatest changes in the Solar System will come from changes in the Sun itself as it ages. As the Sun burns through its supply of hydrogen fuel, it gets hotter and burns the remaining fuel even faster. As a result, the Sun is growing brighter at a rate of ten percent every 1.1 billion years. In about 600 million years, the Sun brightness will have disrupted the Carbon Cycle to the point that trees and forests (C3 photosynthetic plant life) will no longer be able to survive and in around 800 million years, the Sun will have killed all complex life on the Earth's surface and in the oceans. In 1.1 billion years' time, the Sun's increased radiation output will cause its circumstellar habitable zone to move outwards, making the Earth's surface too hot for liquid water to exist there naturally. At this point, all life will be reduced to single celled organisms. Evaporation of water, a potent greenhouse gas, from the oceans' surface could accelerate temperature increase, potentially ending all life on Earth even sooner. During this time, it is possible that as Mars's surface temperature gradually rises, carbon dioxide and water currently frozen under the surface regolith will release into the atmosphere, creating a greenhouse effect that will heat the planet until it achieves conditions parallel to Earth today, providing a potential future abode for life. By 3.5 billion years from now, Earth's surface conditions will be similar to those of Venus today. and the situation: Rob knows a brilliant scientist who has made a time machine. One day, the scientist let Rob travel time with his machine. Rob noticed that the machine had four gears, gear A, gear B, gear C, and gear D. Rob started with Gear A, which represented the present time. Then he pushed the gear to gear B, which was 600 million years from now. Then he further pushed the gear to gear C, which brought him to 800 million years from now. Finally, he pushed the gear to gear D, which brought him to 1.1 billion years from now. Though he traveled time, Rob was always on Earth all the time. Answer the following question: When Rob would see less liquid water on Earth's surface, gear C or gear D?
****
[A]: gear D

input: Please answer the following: Given the background: Besides anthropogenic productivity of the land, the biodiversity of degraded land also declines, as previously mentioned.[12] With less biodiversity, this ecosystem is less adaptable to when disasters strike it[11][8] It has a smaller available food supply, in terms of plants, for animals, who then may die out or more likely may relocate. Proof of this decline is that presently 15-20% of Tibetan Plateau species are now considered endangered; and now because of this animal and plant absence, the soil quality of these degraded lands is very poor.[1] It does not hold the necessary nutrients, such as water, nitrogen, and carbon, essential to either supporting life or inviting life back to that land.[6] As a result of such carbon and nitrogen loss in the Tibetan Plateau, $8,033/ha and $13,315/ha were respectively lost in economic terms. Soils are further weakened by dust storms whose frequency increases because of degradation.[11][4] Erosion of soil becomes a bigger problem, since no longer are there as many plants to anchor in the soil. In the northern Chinese province alone, 400 million are affected every year with an associated 54 billion yuan of annual economic loss due to grassland degradation. and the situation: The Gorge saw some negative effects due to deforestation. The Valley has a more fertile soil, it's not overgrazed, and the trees and bushes are abundant, and the productivity has increased several fold over the past decade. Biodiversity in the Valley is varied, and the soils are nutritious and retain more water, nitrogen and carbon. Answer the following question: Which area has more endangered species?
++++++++++
output: The Gorge

Please answer this: Given the background: Rural development is the process of improving the quality of life and economic well-being of people living in rural areas, often relatively isolated and sparsely populated areas.[1] Rural development has traditionally centered on the exploitation of land-intensive natural resources such as agriculture and forestry. However, changes in global production networks and increased urbanization have changed the character of rural areas. Increasingly tourism, niche manufacturers, and recreation have replaced resource extraction and agriculture as dominant economic drivers.[2] The need for rural communities to approach development from a wider perspective has created more focus on a broad range of development goals rather than merely creating incentive for agricultural or resource based businesses. Education, entrepreneurship, physical infrastructure, and social infrastructure all play an important role in developing rural regions.[3] Rural development is also characterized by its emphasis on locally produced economic development strategies.[4] In contrast to urban regions, which have many similarities, rural areas are highly distinctive from one another. For this reason there are a large variety of rural development approaches used globally.[5] Rural development is a comprehensive term. It essentially focuses on action for the development of areas outside the mainstream urban economic system. we should think of what type of rural development is needed because modernization of village leads to urbanization and village environment disappears. and the situation: Two rural communities from Jones county took different approaches on rural development as a means of adapting to increasing urbanization. Kent village remained traditionally centered on the exploitation of land-intensive natural resources such as agriculture and forestry. Long Grove on the other hand took a wider perspective and created more focus on a broad range of development goals rather than merely creating incentive for agricultural or resource based businesses. Education, entrepreneurship, physical infrastructure, and social infrastructure all played an important role in developing Long Grove village. Answer the following question: Which village took a more complex approach to rural development?
++++++++
Answer: Long Grove

input: Please answer the following: Given the background: Protozoa generally feed by engulfing and digesting other organisms. As consumers, they have various roles in food chains and webs. Some are predators. They prey upon other single-celled organisms, such as bacteria. In fact, protozoa predators keep many bacterial populations in check. Other protozoa are herbivores. They graze on algae. Still others are decomposers. They consume dead organic matter. There are also parasitic protozoa that live in or on living hosts. For example, the protozoan that causes malaria lives inside a human host. For their part, protozoa are important food sources for many larger organisms, including insects and worms. and the situation: Reed started studying protozoa and was more interested in the predatorial behaviors of protozoa, while Brad wanted to know more about other types of protozoa, suck as grazers and decomposers. Answer the following question: Which person learned less about protozoa that graze on algae?
++++++++++
output:
Reed
