input question: You are given a new situation: Steve and Chris sit down at a new cafe that just opened up in town after hearing rave reviews of it at work. They look at the menus trying to decide what to order when a waiter shows up and asks if they would like anything to drink. Steve says he would like a glass of water that has molecules far apart. Chris orders water with molecules closer together. The waiter looks at them with a rather confused look and asks them to please elaborate. and a hint : Liquid water is a fluid. The hydrogen bonds in liquid water constantly break and reform as the water molecules tumble past one another. As water cools, its molecular motion slows and the molecules move gradually closer to one another. The density of any liquid increases as its temperature decreases. For most liquids, this continues as the liquid freezes and the solid state is denser than the liquid state. However, water behaves differently. It actually reaches its highest density at about 4C. Please answer this question : Which person's water is closer to a solid state????
output answer: Chris

You are given a new situation: Timber village started a channelization process by draining all the swamps near their village. Hill village situated 10 miles to the south, left their swamps untouched. and a hint : Ecologically, the expansion of drainage systems has had tremendous negative effects. Hundreds of thousands of wetland species experienced significant population declines as their habitat was increasingly fragmented and destroyed. Although market hunting within the Central Flyway was a contributing factor in the decline of many waterfowl species' numbers in the early decades of the twentieth century, loss of breeding habitat to agricultural expansion is certainly the most significant. Early maps of midwestern states depict many lakes and marshes that are either nonexistent or significantly reduced in area today. Channelization, a related process of concentrating and facilitating the flow of water from agricultural areas, also contributed to this degradation. Please answer this question : Which village experienced no decline in waterfowl species?
----
Answer: Hill

Q: You are given a new situation: Mike is studying the predator prey relationship. He is specifically studying three species, species A, species B, and species C. Species A is a predator; species B is the prey; and species C is a plant species that species B lives on. Mike now needs to figure out how the predator prey relationship balance the ecosystem. and a hint : 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. Please answer this question : If species A population stay stable, would the population of species B increase or not increase?
A: not increase

Question: You are given a new situation: Two brothers liked natural sciences. Ben decided to study Ecology, while his brother Dan decided to study Geography. They studied a lot and became very good at these subjects. and a hint : Ecology is the study of ecosystems. An ecosystem consists of all the living and nonliving components of the habitat. Whereas nutrients and certain elements are recycled through ecosystems, energy moves in just one direction. Many interactions among species within an ecosystem are centered around the flow of energy. The formation of ecosystems, from new land to current habitats, is usually based on the pioneer species, and these species are able to live in an area due to the nonliving factors, such as the climate, the soil and the amount of rainfall, of that area. The populations within an ecosystem also determine the stability of the system. Recent tremendous increases in the human population have raised many important ecological issues. Please answer this question : Which brother studied the flow of energy more?
Answer: Ben

[Q]: You are given a new situation: Croatia and Italy were two countries of similar size and population located on opposite shores of the same sea. Croatia based its economy on tourism and fishing, while Italy based its economy on conventional agriculture. Both countries had thriving economies, but they both polluted the sea in different ways. and a hint : Marine pollution is a generic term for the entry into the ocean of potentially hazardous chemicals or particles. The biggest culprits are rivers and with them many agriculture fertilizer chemicals as well as livestock and human waste. The excess of oxygen-depleting chemicals leads to hypoxia and the creation of a dead zone.Marine debris, which is also known as marine litter, describes human-created waste floating in a body of water. Oceanic debris tends to accumulate at the center of gyres and coastlines, frequently washing aground where it is known as beach litter. Please answer this question : Which country caused the formation of more dead zones?
****
[A]: Italy

Problem: Given the question: You are given a new situation: Two Islands were discovered by settlers, A small group of people moved to South island, but most of them moved to North island. People on North island had frequent food shortages. and a hint : In nature, when the population size is small, there is usually plenty of food and other resources for each individual. When there is plenty of food and other resources, organisms can easily reproduce, so the birth rate is high. As the population increases, the food supply, or the supply of another necessary resource, may decrease. When necessary resources, such as food, decrease, some individuals will die. Overall, the population cannot reproduce at the same rate, so the birth rates drop. This will cause the population growth rate to decrease. Please answer this question : Which island had more people dying?
++++++++++++++++++++++++++++++++
The answer is:
North
