input: Please answer the following: Background: A major use for petroleum products is fuel for cars, trucks, airplanes, trains, and other vehicles. The chemical used are usually a mixture of compounds containing several carbon atoms in a chain. When the material is ignited, a massive amount of gas is created almost instantaneously. This increase in volume will move the pistons in an internal combustion engine to provide power. A jet plane works on a similar principle. Air comes into the front of the engine and mixes with the jet fuel. This mixture is ignited and the gases formed create a lot of pressure to push the plane forward. The idea can be seen even more clearly in the case of a rocket launch. The ignition of the fuel (either solid-state or liquid) creates gases produced under great pressure that pushes the rocket up. Paragraph: Two sister countries used petroleum in different ways. Norway used it to make plastics, while Sweden used it for fuel. Given the paragraph above, please answer correctly the following question: Which country used less fuel to power cars?
++++++++++
output: Norway

Please answer this: Background: A wood-decay fungus is any species of fungus that digests moist wood, causing it to rot. Some species of wood-decay fungi attack dead wood, such as brown rot, and some, such as Armillaria (honey fungus), are parasitic and colonize living trees. Excessive moisture above the fibre saturation point in wood is required for fungal colonization and proliferation.[1] Fungi that not only grow on wood but permeate its fibrous structure and actually cause decay, are called lignicolous fungi. In nature, this process causes the breakdown of complex molecules and leads to the return of nutrients to the soil.[2] Various lignicolous fungi consume wood in various ways; for example, some attack the carbohydrates in wood and some others decay lignin. The rate of decay of wooden materials in various climates can be estimated by empirical models.[3] Paragraph: The mycologist wanted to move to a rural area, to further his research, and found these two villages situated 10 miles from each other. The interesting fact about these villages was that while both villages had a forest nearby, one presented more signs of water saturation than the other, so that the rate of decay in wood was greater in Peak Forest. More fungi were present in Peak Forest. The Valley Forest was dryer, although the rain amounts were similar, partially because of a drainage system composed of ditches, that were dug by the locals. The rate of wood decay continued to increase in the Peak Forest, while being significantly reduced in the Valley Forest. Given the paragraph above, please answer correctly the following question: Which forest will have more brown rot?
++++++++
Answer: Peak Forest

Problem: Background: It would be very unadvisable to place a can of soup over a campfire without venting the can. As the can heats up, it may explode. The kinetic-molecular theory explains why. The air inside the rigid can of soup is given more kinetic energy by the heat coming from the campfire. The kinetic energy causes the air molecules to move faster and they impact the container walls more frequently and with more force. The increase in pressure inside may eventually exceed the strength of the can and it will explode. An additional factor is that the soup may begin boiling which will then aid even more gas and more pressure to the inside of the can. Paragraph: A team of hikers split into two groups. Group Jones hiked north and camped there overnight. Group George went east. Both groups made campfires and heated cans of soups. Group Jones didn't make holes in the cans, so the cans exploded. The others heated their soup cans the right way, by venting them first. Given the paragraph above, please answer correctly the following question: Which group's cans didn't experience an increase in pressure inside the can that exceeded the strength of the can?

A: George

Problem: Given the question: Background: A mycorrhiza (Greek for "fungus roots") is a symbiotic association between a fungus and the roots of a plant. In a mycorrhizal association, the fungus may colonize the roots of a host plant by either growing directly into the root cells, or by growing around the root cells. This association provides the fungus with relatively constant and direct access to glucose, which the plant produces by photosynthesis. The mycelia of the fungi increase the surface area of the plant's root system. The larger surface area improves water and mineral nutrient absorption from the soil. Paragraph: Two mycologists were studying fungi. Jim studied more about wood eating mushrooms and gourmet mushrooms, while George decided to study more about mycorrhiza, and its benefits for humans. Given the paragraph above, please answer correctly the following question: Which mycologist learned less about fungus growing around the root cells?
++++++++++++++++++++++++++++++++
The answer is:
Jim

input question: Background: 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. Paragraph: Jake and his son Ryan just had their yearly physical examination by the doctor. As part of this year's examination, both men had their arterial walls examined to identify the presence of plaques. The doctor discovered that Jake had a high amount of plaques present on the interior of his arterial wall. Ryan, on the other hand, had no plaques present. Given the paragraph above, please answer correctly the following question: Who is more likely to have high blood pressure????
output answer: Jake

input question: Background: 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. Paragraph: Two brothers were land owners. Bill owned 40 acres of forest, , with very well developed soil. His brother Rick owned 40 acres of grasslands, with a poor soil. Rick decided to sell his land. Given the paragraph above, please answer correctly the following question: Which brother owned a land which had slow rates of decomposition????
output answer:
Bill
