Problem: I read this background article the other day: Rain dissolves fertilizer in the soil. Runoff carries it away. The fertilizer ends up in bodies of water, from ponds to oceans. Nitrogen is a fertilizer in the water. Since there is a lot of nitrogen, it causes algae to grow out of control. Pictured below is a pond covered with algae ( Figure below ). Algae use up carbon dioxide in the water. After the algae die, decomposers break down the dead tissue. The decomposers use up all the oxygen in the water. This creates a dead zone. A dead zone is an area in a body of water where nothing grows because there is too little oxygen. There is a large dead zone in the Gulf of Mexico ( Figure below ). The U.S. states outlined on the map have rivers that drain into the Gulf of Mexico. The rivers drain vast agricultural lands. The water carries fertilizer from these areas into the Gulf.  I am facing a new situation today: Park farm and Fiddle farm provided Red city with tonnes of produce annually. Fiddle farm used and abundance of fertilizers and pesticides, while Park farm didn't use any of those substances.  Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which farm caused more algae to grow out of control?

A: Fiddle

Problem: Given the question: I read this background article the other day: Air pollution is harmful to human beings and other living things. About 22 million people die from air pollution each year. Breathing polluted air increases the risk of developing lung diseases such as asthma and lung cancer. Breathing bad air also increases the chances of dying from other diseases. Children are most likely to be affected by air pollution. That’s because their lungs are still developing and growing. Children also take in more air for their size than adults do. Some air pollutants damage the environment as well as the health of living things. The type of damage depends on the pollutant. Air pollution can also harm the environment.  I am facing a new situation today: Daniel visited two countries. Switzerland and India. There was almost no air pollution at all in Switzerland, while the air in India was almost impossible to breathe it was so polluted.  Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which country had more environmental damage because of air pollution?
++++++++++++++++++++++++++++++++
The answer is:
India

input question: I read this background article the other day: As a liquid is heated, the average kinetic energy of its particles increases. The rate of evaporation increases as more and more molecules are able to escape the liquid’s surface into the vapor phase. Eventually a point is reached when the molecules all throughout the liquid have enough kinetic energy to vaporize . At this point the liquid begins to boil. The boiling point is the temperature at which the vapor pressure of a liquid is equal to the external pressure. The Figure below illustrates the boiling of liquid.  I am facing a new situation today: Alexander is heating up water in his kitchen because he is preparing to make pasta. He has split the water into two containers, container A and container B. Container A has been heating up for a long amount time, while container B has only been heating up for a short amount of time.  Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Liquid from which container will boil sooner????
output answer: container A

I read this background article the other day: A lake (from Latin lacus) is a terrain feature (or physical feature), a body of liquid on the surface of a world that is localized to the bottom of basin (another type of landform or terrain feature; that is, it is not global) and moves slowly if it moves at all. On Earth, a body of water is considered a lake when it is inland, not part of the ocean, is larger and deeper than a pond, and is fed by a river. The only world other than Earth known to harbor lakes is Titan, Saturn's largest moon, which has lakes of ethane, most likely mixed with methane. It is not known if Titan's lakes are fed by rivers, though Titan's surface is carved by numerous river beds. Natural lakes on Earth are generally found in mountainous areas, rift zones, and areas with ongoing or recent glaciation. Other lakes are found in endorheic basins or along the courses of mature rivers. In some parts of the world, there are many lakes because of chaotic drainage patterns left over from the last Ice Age. All lakes are temporary over geologic time scales, as they will slowly fill in with sediments or spill out of the basin containing them.  I am facing a new situation today: John wanted to know what makes a lake different from a pond. To that end, he first visited a lake. He labeled that part of the study as case A. Then he visited a pond. He labeled that part of the study as case B. John realized that though both of them were water-bodies, they were very different.  Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which water-body would most likely be fed by a river, case A or case B?
----
Answer: case A

Q: I read this background article the other day: Electric potential energy comes from the position of a charged particle in an electric field. For example, when two negative charges are close together, they have potential energy because they repel each other and have the potential to push apart. If the charges actually move apart, their potential energy decreases. Electric charges always move spontaneously from a position where they have higher potential energy to a position where they have lower potential energy. This is like water falling over a dam from an area of higher to lower potential energy due to gravity.  I am facing a new situation today: David is interested in how electricity works. One day he had two electric charges to investigate, charge A and charge B - both of the charges were negative. He also had two electric fields, field C and field D. He noticed that electric charges were moving from field C to field D.  Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: If charge A and charge B are farther, would their potential energy increase or decrease?
A: decrease

[Q]: I read this background article the other day: Other pathogens spread when they get on objects or surfaces. A fungus may spread in this way. For example, you can pick up the fungus that causes athlete’s foot by wearing shoes that an infected person has worn. You can also pick up this fungus from the floor of a public shower or other damp areas. After acne, athlete’s foot is the most common skin disease in the United States. Therefore, the chance of coming in contact with the fungus in one of these ways is fairly high.  I am facing a new situation today: Two brothers worked out a few times per week at the same gym. Tim got athlete's food from the gym, but Dan didn't.  Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which brother picked up the fungus from the floor of a public shower?
****
[A]:
Tim
