Problem: Given the question: I read this background article the other day: Another major cause of extinction is global warming , which is also known as global climate change. During the past century, the Earth's average temperature has risen by almost 1C (about 1.3F). You may not think that is significant, but to organisms that live in the wild and are constantly adapting to their environments, any climate change can be hazardous. Recall that burning fossil fuels releases gasses into the atmosphere that warm the Earth. Our increased use of fossil fuels, such as coal and oil, is changing the Earth's climate. Any long-term change in the climate can destroy the habitat of a species. Even a brief change in climate may be too stressful for an organism to survive. For example, if the seas increase in temperature, even briefly, it may be too warm for certain types of fish to reproduce. I am facing a new situation today: Two students studied for the biology exam. Ken studied about global warming, while Hank studied about Earth's atmosphere. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which student learned more about Earth's average temperature?

The answer is:
Ken
input question: I read this background article the other day: Chemical reactions follow the laws of thermodynamics. The First Law of Thermodynamics states that energy can be changed from one form to another, but it cannot be created or destroyed. This law is also known as the Law of Conservation of Energy. The Second Law of Thermodynamics states the energy available after a chemical reaction is always less than that at the beginning of a reaction. This is also commonly referred to as entropy. Entropy can be described as the degree of disorder in a system . That is, as energy is transferred from one form to another, some of the energy is lost as heat, and the amount of available energy decreases. As the energy decreases, the disorder in the system increases, and, by definition, the entropy increases. Ice melting provides an example in which entropy increases. Entropy essentially is a measure of the tendency of a process, such as a chemical reaction, to proceed in a particular direction. I am facing a new situation today: Marcus is in a lab working on an experiment. He combines two chemicals to see if they react and the solution starts to boil. He notices that the air above the chemicals reacting has greatly increased in heat. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Will the boiling solution Marcus made have more or less energy when it finishes reacting????
output answer: less
I read this background article the other day: Active transport occurs when a substance passes through the cell membrane with the help of extra energy. This happens when a substance moves from an area where it is less concentrated to an area where it is more concentrated. This is the opposite of diffusion. The substance moves up, instead of down, the concentration gradient. Like rolling a ball uphill, this requires an input of energy. The energy comes from the molecule named ATP (adenosine triphosphate). The energy allows special transport proteins called pumps to move substances to areas of higher concentration. An example is the sodium-potassium pump. I am facing a new situation today: John is trying to figure out how substance passes through the cell membrane. He noticed two different cases, case A and case B. In case A active transport is involved, but in case B diffusion is involved. He needs to do further study to learn about the details of these processes. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: In case A, would the substance move towards less or more concentrated area than in case B?

Answer: more
Q: I read this background article the other day: A red giant star is a star with a mass like the Sun that is in the last phase of its life, when Hydrogen fusion reactions in the core decrease due to the lack of fuel. With the gravitational collapse of the core, the fusion reactions now occur in a shell surrounding the core. The outer layer of the star expands enormously up to 1000 times the size of the Sun. When the Sun becomes a red giant, its volume will include the orbit of Mercury and Venus and maybe even Earth. The increased size increases the luminosity even though the outer layer cools to only 3000 K or so. The cooler outer layer causes it to be a red star. After a few more million years, the star evolves into a white dwarf-planetary nebula system. I am facing a new situation today: Two stars have just been discovered that are identical in terms of chemical composition. The scientist who discovered them was given the right to name them, and he chose the names Enterprise and Vader. As said before, these stars are very similar, but the main difference is that Vader is a red giant, and Enterprise is not. Scientists are very eager to study these two newly discovered stars and see if they can learn anything new from them. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which star has less hydrogen reactions in its core?
A: Vader
Question: I read this background article the other day: HIV , or human immunodeficiency virus, causes AIDS. AIDS stands for "acquired immune deficiency syndrome." It is a condition that causes death and does not have a known cure. AIDS usually develops 10 to 15 years after a person is first infected with HIV. The development of AIDS can be delayed with proper medicines. The delay can be well over 20 years with the right medicines. Today, individuals who acquire HIV after 50 years of age can expect to reach an average human life span. I am facing a new situation today: Tom and Andy are two old friends. Tom was infected with HIV 20 years ago, and Andy has been helping him ever since. Andy is as healthy as an ox. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which friend doesn't have a condition that causes death?
Answer: Andy
Please answer this: I read this background article the other day: Distance decay is a geographical term which describes the effect of distance on cultural or spatial interactions. The distance decay effect states that the interaction between two locales declines as the distance between them increases. Once the distance is outside of the two locales' activity space, their interactions begin to decrease. With the advent of faster travel, distance has less effect than it did in the past, except where places previously connected by now-abandoned railways, for example, have fallen off the beaten path. Advances in communications technology, such as telegraphs, telephones, broadcasting, and internet, have further decreased the effects of distance.[1] I am facing a new situation today: Two neighboring countries with similar economies, followed different political and economical agendas. Niger developed its infrastructure and communications technology, while Nigeria didn't. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which country will be more developed as a consequence of their agendas?
++++++++
Answer:
Niger
