[Q]: You are given a new situation: Bobby and Kenny are two prolific farmers from Arkansas who have ponds located down stream from their farm sites. Bobby recently received a large order of potatoes from a neighboring city. Because of this order, Bobby has dramatically increased the amount of fertilizer he is using on his farm. Kenny mainly grows tomatoes, which are not in season right now, so his use of fertilizer is currently low. Over the past month there has been a large amount of rain falling on both Bobby and Kenny's farms. and a hint : 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. Please answer this question : Who will cause less fertilizer to end up in the ponds near their farm?
****
[A]: Kenny

input: Please answer the following: You are given a new situation: David is a physicist. He teaches school children how matters and energy work. One day he was teaching them about two particles of matter, particle A and particle B. Particle A moves faster, but particle B moves slower. He was showing the children about different characteristics of moving particles. and a hint : No doubt you already have a good idea of what temperature is. You might say that it's how warm or cool something feels. In physics, temperature is defined as the average kinetic energy of the particles of matter. When particles of matter move more quickly, they have more kinetic energy, so their temperature is higher. With a higher temperature, matter feels warmer. When particles move more slowly, they have less kinetic energy on average, so their temperature is lower. With a lower temperature, matter feels cooler. Please answer this question : Which particle would have lower temperature, particle A or particle B?
++++++++++
output: particle B

Please answer this: You are given a new situation: Bob works for the local electric power company. Part of is job involves checking the generators and transformers. His work schedule allows him to work on the generator tagged as gen A only on Mondays, and the transformer tagged as tran B only on Tuesdays. and a hint : Two important devices depend on electromagnetic induction: electric generators and electric transformers. Both devices play critical roles in producing and regulating the electric current we depend on in our daily lives. Electric generators use electromagnetic induction to change kinetic energy to electrical energy. They produce electricity in power plants. Electric transformers use electromagnetic induction to change the voltage of electric current. Some transformers increase voltage and other decrease voltage. Please answer this question : Which one would change the voltage of electric current, gen A or tran B?
++++++++
Answer: tran B

Problem: You are given a new situation: Drought is major concern in the Midwest. To confront the problem scientists are trying to develop drought-resistant crops. To that end, they took a plant that was not exposed to drought. They labeled it as plant A. Then they took a similar plant, and repeatedly exposed it to drought. They labeled it as plant B. They wanted to find out what makes a plant drought-resistant. and a hint : One interesting thing that has been found in plants that are consistently exposed to drought, is their ability to form a sort of "memory". In a study by Tombesi et al., they found plants who had previously been exposed to drought were able to come up with a sort of strategy to minimize water loss and decrease water use. They found that plants who were exposed to drought conditions actually changed they way the regulated their stomates and what they called "hydraulic safety margin" so as to decrease the venerability of the plant. By changing the regulation of stomata and subsequently the transpiration, plants were able to function better in situations where the availability of water decreased. Please answer this question : Which plant would change the regulation of their stomata, plant A or plant B?

A: plant B

Problem: Given the question: You are given 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. and a hint : 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. Please answer this question : Which farmer didn't increase the extraradical hyphal network that can colonize the roots of the new crop?
++++++++++++++++++++++++++++++++
The answer is:
Bubba

Problem: You are given a new situation: Berg village and Hill village are renowned for the high number of cyclists living there. Berg village dealt with many traffic casualties because of narrower streets and lanes, While Hill village had wide streets, more traffic signals and a greater number of cyclists. and a hint : Turner et al (2006) derived crash prediction models for this report's predecessor and found a pronounced 'safety in numbers' effect in the models. Using the crash prediction model for mid-block locations, generic motorist and cyclist volumes can be used to demonstrate the impacts on the expected crash rate of varying motor vehicle and cycle volumes. As shown in figure 2.20, an increase in the proportion of cyclists to the overall traffic volume causes an increase in expected crashes at mid-block locations, but the crash rate increases at a decreasing rate. That is to say, the crash rate per cyclist goes down as the cycle volume increases. Please answer this question : Which village had a greater traffic volume?

A:
Hill
