[Q]: You are given a new situation: The Berg mountains in Berg county are of a volcanic nature, very massive, few caves. The Gorge mountains in Gorge county are made of sedimentary rocks, predominantly limestone. They were exposed to water and that lead to karst lanscapes, caves, blue holes, stalactites and stalagmites. and a hint : About 10% of sedimentary rocks are limestones. The solubility of limestone in water and weak acid solutions leads to karst landscapes, in which water erodes the limestone over thousands to millions of years. Most cave systems are through limestone bedrock. Please answer this question : Which of the two mountains had more blue holes?
****
[A]: Gorge

[Q]: You are given a new situation: Ben and Andy researched significant greenhouse gasses in Earth's atmosphere. Andy researched more about carbon dioxide, while Ben researched methane gas. and a hint : Carbon dioxide is the most significant long-lived greenhouse gas in Earth's atmosphere. Since the Industrial Revolution anthropogenic emissions primarily from use of fossil fuels and deforestation have rapidly increased its concentration in the atmosphere, leading to global warming. Carbon dioxide also causes ocean acidification because it dissolves in water to form carbonic acid. Please answer this question : Which researcher studied more about deforestation?
****
[A]: Andy

[Q]: You are given a new situation: Pete liked the human physiology so he started reading about the digestive system, especially about the jejunum. His colleague Fox, studied more about the stomach. and a hint : The jejunum is the second part of the small intestine, where most nutrients are absorbed into the blood. As shown in Figure below , the mucous membrane lining the jejunum is covered with millions of microscopic, fingerlike projections called villi (singular, villus). Villi contain many capillaries, and nutrients pass from the villi into the bloodstream through the capillaries. Because there are so many villi, they greatly increase the surface area for absorption. In fact, they make the inner surface of the small intestine as large as a tennis court! Please answer this question : Which student read more about how nutrients pass from the villi into the bloodstream through the capillaries?

[A]: Pete

[Q]: You are given a new situation: Two boys read about the Earth, Evolutionism and the Gaia hypothesis. Brad liked Evolutionism more, while Stan preferred the Gaia theory, and agreed with it. and a hint : The Gaia hypothesis states that the biosphere is its own living organism. The hypothesis suggests that the Earth is self-regulating and tends to achieve a stable state, known as homeostasis . For example the composition of our atmosphere stays fairly consistent, providing the ideal conditions for life. When carbon dioxide levels increase in the atmosphere, plants grow more quickly. As their growth continues, they remove more carbon dioxide from the atmosphere. In this way, the amount of carbon dioxide stays fairly constant without human intervention. Please answer this question : Which boy agreed that the amount of carbon dioxide stays fairly constant without human intervention?

[A]:
Stan
