Problem: Given the question: I have a new situation: Students learned about protozoa in school this week. Dan and Jim were interested and read more on the subject. Dan read more about predatory protozoa, while Jim read more about herbivore protozoa. But I can use this background: Protozoa generally feed by engulfing and digesting other organisms. As consumers, they have various roles in food chains and webs. Some are predators. They prey upon other single-celled organisms, such as bacteria. In fact, protozoa predators keep many bacterial populations in check. Other protozoa are herbivores. They graze on algae. Still others are decomposers. They consume dead organic matter. There are also parasitic protozoa that live in or on living hosts. For example, the protozoan that causes malaria lives inside a human host. For their part, protozoa are important food sources for many larger organisms, including insects and worms. What is an answer for this question: Which student read more about protozoa preying upon single-celled organisms?

The answer is:
Dan
input question: I have a new situation: The Berg mountains in Berg county are of a volcanic nature, very massive, few caves. The Gorge mountains in Gorge county are made of sedimentary rocks, predominantly limestone. They were exposed to water and that lead to karst lanscapes, caves, blue holes, stalactites and stalagmites. But I can use this background: About 10% of sedimentary rocks are limestones. The solubility of limestone in water and weak acid solutions leads to karst landscapes, in which water erodes the limestone over thousands to millions of years. Most cave systems are through limestone bedrock. What is an answer for this question: Which of the two mountains had fewer karst landscapes????
output answer: Berg
I have a new situation: Two pedologists studied different types of soil. Yun studied forest soils, while Jian studied grassland soil. They were both very surprised with they findings. 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 scientist read less about the principal source of soil organic matter in the forest?

Answer: Jian
Q: I have a new situation: Two teams studied two types of animals: team A studied predators, while team B studied grazers. They learned a lot from this experience. But I can use this background: Predators play an important role in an ecosystem. For example, if they did not exist, then a single species could become dominant over others. Grazers on a grassland keep grass from growing out of control. Predators can be keystone species . These are species that can have a large effect on the balance of organisms in an ecosystem. For example, if all of the wolves are removed from a population, then the population of deer or rabbits may increase. If there are too many deer, then they may decrease the amount of plants or grasses in the ecosystem. Decreased levels of producers may then have a detrimental effect on the whole ecosystem. In this example, the wolves would be a keystone species. What is an answer for this question: Which team learned less about wolves?
A: team B
Question: I have a new situation: Gary and Joe are two farmers. Joe's farm has a depleted soil, while Gary started agroforestry a few years back, and grows cover crops. But I can use this background: Depleted soils can be protected from soil erosion by groundcover plants such as naturally growing grasses in agroforestry systems. These help to stabilise the soil as they increase cover compared to short-cycle cropping systems. Soil cover is a crucial factor in preventing erosion. Cleaner water through reduced nutrient and soil surface runoff can be a further advantage of agroforestry. The runoff can be reduced by decreasing its velocity and increasing infiltration into the soil. Compared to row-cropped fields nutrient uptake can be higher and reduce nutrient loss into streams.Further advantages concerning plant growth: What is an answer for this question: Which farmer increased infiltration to prevent erosion?
Answer: Gary
Please answer this: I have a new situation: John and Keith are playing a decision making game. They have three decisions to make decision A, decision B, and decision C. Decision A and decision B have certain outcome, but decision C's outcome is uncertain. John would apply optimal decision making process while Keith would rather rely on his hunches. But I can use this background: An optimal decision is a decision that leads to at least as good a known or expected outcome as all other available decision options. It is an important concept in decision theory. In order to compare the different decision outcomes, one commonly assigns a utility value to each of them. If there is uncertainty as to what the outcome will be, then under the von NeumannMorgenstern axioms the optimal decision maximizes the expected utility (a probabilityweighted average of utility over all possible outcomes of a decision). What is an answer for this question: Who would most likely make decisions at least as good a known or expected outcome, John or Keith?
