Problem: I have a new situation: Dan is conducting a research to see how a substance behaves in varying pressure. First, he selects a gaseous substance in very low pressure. He calls it as case A. Then he increases the pressure. He calls it case B. Finally, he increases the pressure even further. He calls it case C. But I can use this background: Start right above point on the temperature axis and follow the red line vertically. At very low pressure, the particles of the substance are far apart from one another and the substance is in the gas state. As the pressure is increased, the particles of the substance are forced closer and closer together. Eventually the particles are pushed so close together that attractive forces cause the substance to condense into the liquid state. Continually increasing the pressure on the liquid will eventually cause the substance to solidify. For the majority of substances, the solid state is denser than the liquid state and so putting a liquid under great pressure will cause it to turn into a solid. The line segment represents the process of sublimation, where the substance changes directly from a solid to a gas. At a sufficiently low pressure, the liquid phase does not exist. The point labeled is called the triple point . The triple point is the one condition of temperature and pressure where the solid, liquid, and vapor states of a substance can all coexist at equilibrium. What is an answer for this question: Which case would most likely see the substance turning into solid, case B or case C?

A: case C
Problem: Given the question: I have a new situation: Two neighboring towns used different approaches to agriculture. Big town used pesticides and fertilizers, while Small town applied permaculture principles and organic farming methods. But I can use this background: Huge amounts of chemicals, such as fertilizers and pesticides, are applied to farm fields (see Figure below ). Some of the chemicals are picked up by rainwater. Runoff then carries the chemicals to nearby rivers or lakes. Dissolved fertilizer causes too much growth of water plants and algae. This can lead to dead zones where nothing can live in lakes and at the mouths of rivers. Some of the chemicals can infiltrate into groundwater. The contaminated water comes up in water wells. If people drink the polluted water, they may get sick. What is an answer for this question: Which town had fewer pesticides picked up by rain water?

input question: I have a new situation: 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. But I can use this 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. What is an answer for this question: Which student read more about slow rates of decomposition????
output answer: Brad
I have a new situation: Kim and Jane inherited some land. Kim inherited some grassland, while Jane inherited a forest. They both took good care of their properties. But I can use this background: In grassland, much of the organic matter added to the soil is from the deep, fibrous, grass root systems. By contrast, tree leaves falling on the forest floor are the principal source of soil organic matter in the forest. Another difference is the frequent occurrence in the grasslands of fires that destroy large amounts of aboveground material but stimulate even greater contributions from roots. Also, the much greater acidity under any forests inhibits the action of certain soil organisms that otherwise would mix much of the surface litter into the mineral soil. As a result, the soils under grasslands generally develop a thicker A horizon with a deeper distribution of organic matter than in comparable soils under forests, which characteristically store most of their organic matter in the forest floor (O horizon) and thin A horizon. What is an answer for this question: Which person inherited a parcel where the soil had a lower acidity?
----
Answer: Kim
Q: I have a new situation: Keith is a physician in a local hospital. He is treating a patient with respiratory problem. He looked at two different states of the patient's diaphragm, state A and state B. In state A the the diaphragm contracted, but in state B the diaphragm relaxed. He now needs to figure out other phenomena related to this. But I can use this background: Inhaling is an active movement that results from the contraction of a muscle called the diaphragm. The diaphragm is large, sheet-like muscle below the lungs (see Figure below ). When the diaphragm contracts, the ribcage expands and the contents of the abdomen move downward. This results in a larger chest volume, which decreases air pressure inside the lungs. With lower air pressure inside than outside the lungs, air rushes into the lungs. When the diaphragm relaxes, the opposite events occur. The volume of the chest cavity decreases, air pressure inside the lungs increases, and air flows out of the lungs, like air rushing out of a balloon. What is an answer for this question: When would the air pressure inside lungs decrease, stae A or state B?
A: state A
[Q]: I have a new situation: John has just started working at a new company. Although he has been in the workforce for many years, this is a new position for him, and he is excited for it. Two weeks after starting, John's branch of the company is hosting a retirement party for one of the longest tenured employees at the office, Brad. Although Brad has enjoyed his time at the company, he says he is excited to be able to take time to himself and relax each day instead of coming into the office. But I can use this background: Old age begins in the mid-60s and lasts until the end of life. Many people over 65 have retired from work, freeing up their time for hobbies, grandchildren, and other interests. Stamina, strength, reflex time, and the senses all decline during old age, and the number of brain cells decreases as well. The immune system becomes less efficient, increasing the risk of serious illnesses such as cancer and pneumonia. Diseases such as Alzheimer's disease that cause loss of mental function also become more common. What is an answer for this question: Who would struggle to lift a heavy box more?

[A]:
Brad
