Question: I read this background article the other day: 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. I am facing a new situation today: John is studying a species in two similar countries, country A and country B. Country A has large population, but country B has small population of that species. John is pondering about how this species would fare in the future in these two countries. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: In which country individuals of the species would have more food, country A or country B?
Answer: country B

Question: I read this background article the other day: New species develop naturally through the process of natural selection . Due to natural selection, organisms with traits that better enable them to adapt to their environment will tend to survive and reproduce in greater numbers. Natural selection causes beneficial heritable traits to become more common in a population and unfavorable heritable traits to become less common. For example, a giraffe's neck is beneficial because it allows the giraffe to reach leaves high in trees. Natural selection caused this beneficial trait to become more common than short necks. I am facing a new situation today: Scientists studied two groups of mammals. Group One developed natural selection after a few decades, while group Two didn't. It was yet to be determined why that happened. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which group will develop more naturally because of natural selection?
Answer: Group One

Question: I read this background article the other day: Natural resources include energy, minerals and other materials. Natural resources may be renewable or non-renewable. Non-renewable resources cannot be replaced. When they're gone, they're gone. Renewable resources can be replaced. They can supply human activities forever. Fossil fuels are crucial for modern human society. Fossil fuels are essential for transportation, industry and agriculture. Renewable energy resources tend to be clean. They emit fewer pollutants and greenhouse gases than fossil fuels. Renewable resources often have other problems. They are more costly and less efficient than fossil fuels. Still, they have many advantages. Research is going into developing renewable resources. Conservation is the best way to increase resource availability. Anyone can conserve! You and your family can. Society can. The world can. Just reduce, reuse, recycle. I am facing a new situation today: Germany took steps to increase the use of renewable natural resources. Today, they are the leader in using renewable resources. Most of their energy requirements are met with renewable natural resources. But it's not the case with nearby Russia. Russia has been heavily depended on non-renewable natural resources. With the discovery of huge gas and oil reserves there is no sign that situation would change in Russia any time soon. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Would Germany's natural resources last longer or shorter than Russia's?
Answer:
longer
