Problem: Given the question: Given the background: Windbreaks reduce wind velocity over and around crops. This increases yields through reduced drying of the crop and/or by preventing the crop from toppling in strong wind gusts. and the situation: Two farms had winds destroying their crops. Hill farm started installing windbreaks, while Valley farm didn't have the funds to do that so they postponed the project. Answer the following question: Which farm didn't prevent the crop from toppling?
++++++++++++++++++++++++++++++++
The answer is:
Valley

input question: Given the background: In the U.S., the majority of electricity is produced by burning coal or other fossil fuels. This causes air pollution that harms the health of living things. The air pollution also causes acid rain and contributes to global warming. In addition, fossil fuels are nonrenewable resources, so if we keep using them, they will eventually run out. The main advantage of nuclear energy is that it doesn't release air pollution or cause the other environmental problems associated with the burning of fossil fuels. On the other other hand, radioactive elements are nonrenewable like fossil fuels and could eventually be used up. and the situation: The U.S. produces its energy using fossil fuels, while Germany uses nuclear power plants as their main energy source. The two countries impact the environment in different ways. Answer the following question: Which country contributes more to global warming????
output answer: The U.S.

Given the background: Sand mining is a direct cause of erosion, and impacts the local wildlife.[2] Various animals depend on sandy beaches for nesting clutches, and mining has led to the near extinction of gharials (a species of crocodile) in India. Disturbance of underwater and coastal sand causes turbidity in the water, which is harmful for organisms like coral that need sunlight. It can also destroy fisheries, financially harming their operators. Removal of physical coastal barriers, such as dunes, sometimes leads to flooding of beachside communities, and the destruction of picturesque beaches causes tourism to dissipate. Sand mining is regulated by law in many places, but is often done illegally.[3] Globally, it is a $70 billion industry, with sand selling at up to $90 per cubic yard.[4] and the situation: Two cities located at the sea shore between sand dunes, took 2 different approaches to their economic stability and sources of income for their inhabitants. Dune city was mainly focused on raising cattle, fishing and tourism, while Gulf city started sand mining operations because of the good prices they received per cubic yard of sand. Answer the following question: Which city made less money from tourism?
----
Answer: Gulf

Q: Given the background: 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. and the situation: Two people got stuck in a local blizzard. Tom had a bottle of alcohol with him and drank it after he found some kind of shelter in the snow. Dan didn't have alcohol with him. Answer the following question: Which of the two people had less heat exchange with a cold environment?
A: Dan

Question: Given the background: Nearsightedness, or myopia, is the condition in which nearby objects are seen clearly, but distant objects appear blurry. The Figure below shows how it occurs. The eyeball is longer (from front to back) than normal. This causes images to be focused in front of the retina instead of on the retina. Myopia can be corrected with concave lenses. The lenses focus images farther back in the eye, so they fall on the retina instead of in front of it. and the situation: Two siblings went to the eye doctor, they needed eyeglasses. As it turned out, Ann had myopia, and Jane had farsightedness. They both bought eyeglasses. Answer the following question: Which sister could not perceive distant objects to be blurry?
Answer: Jane

Please answer this: Given the background: Hydrogen bonds cause water to have a relatively high boiling point of 100C (212F). Because of its high boiling point, most water on Earth is in a liquid state rather than in a gaseous state. Water in its liquid state is needed by all living things. Hydrogen bonds also cause water to expand when it freezes. This, in turn, causes ice to have a lower density (mass/volume) than liquid water. The lower density of ice means that it floats on water. For example, in cold climates, ice floats on top of the water in lakes. This allows lake animals such as fish to survive the winter by staying in the water under the ice. and the situation: Marcy is in her kitchen and fills one blue cup with water and then sticks that cup in the freezer. She then takes a green cup and fills that one with water but sets that one out on the kitchen counter. Three hours later, Marcy returns and takes the cup out of the freezer and dumps the now frozen water out onto a plate to look at it and compare it to the water that has been sitting on the kitchen counter. Answer the following question: The water in which color cup will be more dense?
++++++++
Answer:
blue
