Question: I read this background article the other day: Almost all earthquakes occur at plate boundaries. All types of plate boundaries have earthquakes. Convection within the Earth causes the plates to move. As the plates move, stresses build. When the stresses build too much, the rocks break. The break releases the energy that was stored in the rocks. The sudden release of energy creates an earthquake. During an earthquake the rocks usually move several centimeters or rarely as much as a few meters. Elastic rebound theory describes how earthquakes occur ( Figure below ). I am facing a new situation today: Two brothers loved geology. Bob studied sedimentary rocks while Dan studied about earthquakes and their location. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which brother studied more about how rocks usually move several centimeters?
Answer: Dan
[Q]: I read this background article the other day: Precipitation in grasslands is equal to or less than evapotranspiration and causes soil development to operate in relative drought. Leaching and migration of weathering products is therefore decreased. Large amounts of evaporation causes buildup of calcium (Ca) and other large cations flocculate clay minerals and fulvic acids in the upper soil profile. Impermeable clay limits downward percolation of water and fulvic acids, reducing chemical weathering and podzolization. The depth to the maximum concentration of clay increases in areas of increased precipitation and leaching. When leaching is decreased, the Ca precipitates as calcite (CaCO3) in the lower soil levels, a layer known as caliche. I am facing a new situation today: Two farmers had neighboring parcels of land. Bob had a nice parcel of old growth forest, while the other farmer, named Bill , had a similar sized parcel covered in grasslands. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which farmer had soil development operate in relative drought?
****
[A]: Bill
input: Please answer the following: I read this background article the other day: Because of human activities, there is more carbon dioxide in the atmosphere today than in the past hundreds of thousands of years. Burning fossil fuels and has released great quantities of carbon dioxide into the atmosphere. Cutting forests and clearing land has also increased carbon dioxide into the atmosphere because these activities reduce the number of autotrophic organisms that use up carbon dioxide in photosynthesis. In addition, clearing often involves burning, which releases carbon dioxide that was previously stored in autotrophs. I am facing a new situation today: Two cities had different energy source. Big city burned fossil fuels, while Blue city used alternative sources of energy. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which city produced more carbon dioxide?
++++++++++
output: Big
Please answer this: I read this background article the other day: 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] I am facing a new situation today: 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. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which lake has fewer thermoclines?
++++++++
Answer: Shallow lake
Problem: I read this background article the other day: One interesting thing that has been found in plants that are consistently exposed to drought, is their ability to form a sort of "memory". In a study by Tombesi et al., they found plants who had previously been exposed to drought were able to come up with a sort of strategy to minimize water loss and decrease water use. They found that plants who were exposed to drought conditions actually changed they way the regulated their stomates and what they called "hydraulic safety margin" so as to decrease the venerability of the plant. By changing the regulation of stomata and subsequently the transpiration, plants were able to function better in situations where the availability of water decreased. I am facing a new situation today: Drought is major concern in the Midwest. To confront the problem scientists are trying to develop drought-resistant crops. To that end, they took a plant that was not exposed to drought. They labeled it as plant A. Then they took a similar plant, and repeatedly exposed it to drought. They labeled it as plant B. They wanted to find out what makes a plant drought-resistant. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which plant would function better with less water, plant A or plant B?

A: plant B
input: Please answer the following: I read this background article the other day: Cholesterol has been implicated in heart disease for decades. Atherosclerosis is a disorder of the arteries in which cholesterol and other materials are deposited on the interior of the arterial wall. These deposits lead to the formation of plaques that can restrict or even block the flow of blood through these blood vessels (see Figure below ). A decrease in the flow of blood can lead to high blood pressure and a lowered oxygen supply to the heart muscle. A complete blockage of blood flow to parts of the heart (a heart attack) can cause significant damage due to oxygen deprivation, in some cases leading to death. I am facing a new situation today: Bob's parents were in their early 60's. He sent them to the doctor's for a routine check up. Dan, his dad, had very high cholesterol, while Mary, his mom , had normal levels in her blood. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which parent had fewer plaques that could potentially block blood flow?
++++++++++
output:
Mary
