Question: I have a new situation: Bubba and Dean are two farmers which realized the benefits of having AM fungi in their soil. Dean, however, took active steps in helping the growth of AM fungi so he grew cover crops on his lands. But I can use this background: Since AM fungi are biotrophic, they are dependent on plants for the growth of their hyphal networks. Growing a cover crop extends the time for AM growth into the autumn, winter, and spring. Promotion of hyphal growth creates a more extensive hyphal network. The mycorrhizal colonization increase found in cover crops systems may be largely attributed to an increase in the extraradical hyphal network that can colonize the roots of the new crop (Boswell et al. 1998). The extraradical mycelia are able to survive the winter, providing rapid spring colonization and early season symbiosis (McGonigle and Miller 1999). This early symbiosis allows plants to tap into the well-established hyphal network and be supplied with adequate phosphorus nutrition during early growth, which greatly improves the crop yield. What is an answer for this question: Which farmer extended AM fungi growth into the winter?
Answer: Dean
[Q]: I have a new 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. But I can use this 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. What is an answer for this question: Which country causes more air pollution?
****
[A]: The U.S.
input: Please answer the following: I have a new situation: David was interested in the coloration of ocean's water. To understand the phenomenon he first observed the color of water at forty feet depth. He noted his observation as point A. Then he observed the color at hundred feet depth. He noted his observation as point B. Then he observed the color at four thousand feet depth. He noted that observation as point C. He now have some ideas how the color of water changes according to its depth. But I can use this background: Through a thickness of 10 meters (33 ft) or more, however, the intrinsic color of water (or ice) is visibly turquoise (greenish blue), as its absorption spectrum has a sharp minimum at the corresponding color of light (1/227 m1 at 418 nm). The color becomes increasingly stronger and darker with increasing thickness. (Practically no sunlight reaches the parts of the oceans below 1,000 meters (3,300 ft) of depth.) Infrared and ultraviolet light, on the other hand, is strongly absorbed by water. What is an answer for this question: Where there would not be any visible sunlight, point B or point C?
++++++++++
output: point C
Please answer this: I have a new situation: The Malegese Ocean is primarily connected to one river. This river is next to Hilda's farm that she has lived on for decades. Ever since she was a child, she was taught that it's important to dump excess fertilizer into the river. So, that's what she does whenever she has leftover fertilizer she isn't going to use. The Dundrin Ocean is connected to many rivers. However, these rivers are located primarily in uninhabited and natural areas of the world. There is one farm near the Dundrin, though, which is owned by Luke. Luke never disposes of any of his garbage in the ocean or rivers near his farm, and he chooses instead to store excess fertilizer for the future or properly dispose of his trash. But I can use this background: Marine pollution is a generic term for the entry into the ocean of potentially hazardous chemicals or particles. The biggest culprits are rivers and with them many agriculture fertilizer chemicals as well as livestock and human waste. The excess of oxygen-depleting chemicals leads to hypoxia and the creation of a dead zone.Marine debris, which is also known as marine litter, describes human-created waste floating in a body of water. Oceanic debris tends to accumulate at the center of gyres and coastlines, frequently washing aground where it is known as beach litter. What is an answer for this question: Which ocean has less chemicals in it?
++++++++
Answer: Dundrin
Problem: I have a new situation: The island of Utopia is a popular tourist destination with its great sandy beaches. Two of the most popular beaches are beach A and beach B. Both beaches also have large wildlife sanctuaries where rare dolphins can be seen. There are some fisheries in both beaches too. This year the government of Utopia is looking for more sources to increase their revenue. They decided to allow sand mining in beach A next year, and earn some extra revenue. But I can use this 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] What is an answer for this question: Which beach's wildlife sactuary would not suffer next year, beach A or beach B?

A: beach B
input: Please answer the following: I have a new situation: Two students were learning about atmospheres and planets. Dan learned about the atmosphere of Earth, while Nate learned about planet Venus and its atmosphere. But I can use this background: Clouds on Earth are made of water vapor. Venus's clouds are a lot less pleasant. They are made of carbon dioxide, sulfur dioxide and large amounts of corrosive sulfuric acid! The atmosphere of Venus is so thick that the pressure on the surface of Venus is very high. In fact, it is 90 times greater than the pressure at Earth's surface! The thick atmosphere causes a strong greenhouse effect. As a result, Venus is the hottest planet. Even though it is farther from the Sun, Venus is much hotter even than Mercury. Temperatures at the surface reach 465C (860F). That's hot enough to melt lead! What is an answer for this question: Which student learned more about the planet with a strong greenhouse effect?
++++++++++
output:
Nate
