Q: I read this background article the other day: The refraction of waves across boundaries operates similarly to the method by which tanks are steered. Tanks do not have a steering wheel. Instead, they have an accelerator to produce forward motion and separate brakes on each tread. The operator uses brakes on both treads at the same time in order to stop, but brakes on only one tread to turn the tank. By braking one side, the operator causes that side to slow down or stop while the other side continues at the previous speed, causing the tank to turn towards the slower tread. I am facing a new situation today: Benjamin is taking an Army training class and is learning to operate a tank. Today, he is in a tank with an instructor on a training course. Benjamin drives the tank forward and comes to a large dirt mound blocking his path. He needs to decide whether to break the left tread or right tread. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: If the tread on the right is going faster which direction will the tank turn?
A: left
Question: I read this background article the other day: Temperature is a measure of the average kinetic energy of the particles in matter. In everyday usage, temperature indicates a measure of how hot or cold an object is. Temperature is an important parameter in chemistry. When a substance changes from solid to liquid, it is because there was an increase in the temperature of the material. Chemical reactions usually proceed faster if the temperature is increased. Many unstable materials (such as enzymes) will be viable longer at lower temperatures. I am facing a new situation today: Susan went to the store to buy some bags of ice for a party she was having later in the day. When she got home she put one bag of ice in the sink and another in the freezer, but then was distracted by a phone call and forgot to put the other bag in the freezer. When she returned, the bag of ice had melted. Thomas is a research assistant and has taken samples of rat liver enzymes that need to be stored overnight. He places one in refrigerated storage, but forgot one and left it out on the counter top. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Will the sample on the counter have a lower or higher average kinetic energy than the refrigerated sample?
Answer: higher
[Q]: I read this background article the other day: Shown in the Figure below is a cylinder of gas on the left that is at room temperature (300 K). On the right, the cylinder has been heated until the Kelvin temperature has doubled to 600 K. The kinetic energy of the gas molecules increases, so collisions with the walls of the container are now more forceful than they were before. As a result, the pressure of the gas doubles. Decreasing the temperature would have the opposite effect, and the pressure of an enclosed gas would decrease. I am facing a new situation today: Gwen owns a sauna. She wants to try something new and decides to make the room air tight, meaning no air can escape the room. After trialing this with a few customers she asks them for some feedback. The customers say they really like how there is never a draft in the room but they feel weird when they leave the room and their ears pop like when they are are on an airplane and the pressure is uneven. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Will the pressure of a sealed container increase or decrease when a gas inside it is heated?
****
[A]: increase
input: Please answer the following: I read this background article the other day: Arbuscular mycorrhizal fungi vary across many environmental gradients. Their tolerance to freezing and drying is known to shift between AM fungal taxa. AM fungi become less prevalent and diverse at higher soil nutrient and moisture concentrations, presumably because both plants allocate less carbon to AM fungi and AM fungi reallocate their resources to intraradical hyphae in these environmental conditions. Over the long term, these environmental conditions can even create local adaptation between plant hosts, AM fungi and the local soil nutrient concentrations. I am facing a new situation today: Greg and Paul were two neighbors. They were both into mycology. Greg researched AM fungi, while Paul studied other types of mycorrhizal fungi. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which researcher learned more about AM fungi reallocating their resources to intraradical hyphae?
++++++++++
output: Greg
Please answer this: I read this background article the other day: 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. I am facing a new situation today: Austria had two distinct climactic regions. The eastern region was exposed to a wet climate and had thriving vegetation, while the western region was exposed to drought. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which region had fewer plants with an ability to come up with a sort of strategy to minimize water loss?
++++++++
Answer: eastern
Question: I read this background article the other day: So much rain falling so fast causes some of the damage from a hurricane. But a lot of the damage is caused by storm surge. Storm surge is very high water located in the low pressure eye of the hurricane. The very low pressure of the eye allows the water level to rise above normal sea level. Storm surge can cause flooding when it reaches land ( Figure below ). High winds do a great deal of damage in hurricanes. High winds can also create very big waves. If the large waves are atop a storm surge, the high water can flood the shore. If the storm happens to occur at high tide, the water will rise even higher. I am facing a new situation today: Two cities were located 50 miles away from each other. They received a hurricane warning. Twin city got hit by the Hurricane, while Big city missed most of the effects. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which city experienced smaller waves?
Answer:
Big
