input: Please answer the following: I read this background article the other day: Alcoholic beverages do not make the entire body warmer.[361] The reason that alcoholic drinks create the sensation of warmth is that they cause blood vessels to dilate and stimulate nerve endings near the surface of the skin with an influx of warm blood. This can actually result in making the core body temperature lower, as it allows for easier heat exchange with a cold external environment. I am facing a new situation today: A scientist studied the effects of alcoholic beverages on the human body during severe weather exposure. He decided to experiment on himself. He stood in -30 degrees weather for 2 hours and called it experiment A. He then repeated the experiment, the only difference being that he consumed a pint of hard liquor before and during those two hours, and that was called experiment B. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: When did the scientist's blood vessels dilate more, during experiment A, or during B?
++++++++++
output: experiment B
Please answer this: I read this background article the other day: Rainfall in an area is important because it influences the rate of weathering. More rain means that more rainwater passes through the soil. The rainwater reacts chemically with the particles. The top layers of soil are in contact with the freshest water, so reactions are greatest there. High rainfall increases the amount of rock that experiences chemical reactions. High rainfall may also carry material away. This means that new surfaces are exposed. This increases the rate of weathering. I am facing a new situation today: Two parcels of land , parcel Q and parcel H are situated in the same county about 20 miles away. Parcel Q received a greater amount of rainfall than parcel H, therefore the soil was more affected by the rain. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which parcel had more top layers of soil in contact with the freshest water?
++++++++
Answer: parcel Q
Problem: I read this background article the other day: Depleted soils can be protected from soil erosion by groundcover plants such as naturally growing grasses in agroforestry systems. These help to stabilise the soil as they increase cover compared to short-cycle cropping systems. Soil cover is a crucial factor in preventing erosion. Cleaner water through reduced nutrient and soil surface runoff can be a further advantage of agroforestry. The runoff can be reduced by decreasing its velocity and increasing infiltration into the soil. Compared to row-cropped fields nutrient uptake can be higher and reduce nutrient loss into streams.Further advantages concerning plant growth: I am facing a new situation today: Dan, a renowned pedologist, visited two farms near his home town. Grape farm had depleted soils and a low crop production, while Fruit farm, having parcels with depleted soils in the past, established an agroforestry system starting a decade ago which helped stabilize soil and increase production. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which farm obtained cleaner water as a result of their farming methods?

A: Fruit
Problem: Given the question: I read this background article the other day: When humans dig up and use fossil fuels, we have an impact on the carbon cycle ( Figure below ). This carbon is not recycled until it is used by humans. The burning of fossil fuels releases more carbon dioxide into the atmosphere than is used by photosynthesis. So, there is more carbon dioxide entering the atmosphere than is coming out of it. Carbon dioxide is known as a greenhouse gas , since it lets in light energy but does not let heat escape, much like the panes of a greenhouse. The increase of greenhouse gasses in the atmosphere is contributing to a global rise in Earth's temperature, known as global warming or global climate change. I am facing a new situation today: Two villages were focused mostly on mining operation. Brown village extracted fossil fuels such as coal from their mountains, while Yellow village was mostly focused on extracting gold the old fashioned way. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which village has less of an impact on global climate change?
++++++++++++++++++++++++++++++++
The answer is:
Yellow
input question: I read this background article the other day: 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. I am facing a new situation today: Two friends had a sleepover. They spent most of the time online looking up stuff and talking about it. Bill looked up the Gaia hypothesis, while Frank read about the Flat Earth theory. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which friend read less about the biosphere being its own living organism????
output answer: Frank
input question: I read this background article the other day: Soil is well developed in the forest as suggested by the thick humus layers, rich diversity of large trees and animals that live there. In forests, precipitation exceeds evapotranspiration which results in an excess of water that percolates downward through the soil layers. Slow rates of decomposition leads to large amounts of fulvic acid, greatly enhancing chemical weathering. The downward percolation, in conjunction with chemical weathering leaches magnesium (Mg), iron (Fe), and aluminum (Al) from the soil and transports them downward, a process known as podzolization. This process leads to marked contrasts in the appearance and chemistry of the soil layers. I am facing a new situation today: Two students learned about soils in school. Brad had to study forest soils, while his colleague Frank had to study grasslands. They both did a good job and received A's for their efforts and accumulated knowledge. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which student read more about precipitation that exceeds evapotranspiration????
output answer:
Brad
