input: Please answer the following: I can use this background: 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. Now, I have a new situation: Scientists studied two island. One with an old ecosystem named Old island, and the other with a newly formed and forming ecosystem named New island. Both islands were inhabited, Old island being heavily inhabited. Answer this question please: Which island was more favorable for pioneer plants?
++++++++++
output: New island
Please answer this: I can use this background: Clouds on Earth are made of water vapor. Venus's clouds are a lot less pleasant. They are made of carbon dioxide, sulfur dioxide and large amounts of corrosive sulfuric acid! The atmosphere of Venus is so thick that the pressure on the surface of Venus is very high. In fact, it is 90 times greater than the pressure at Earth's surface! The thick atmosphere causes a strong greenhouse effect. As a result, Venus is the hottest planet. Even though it is farther from the Sun, Venus is much hotter even than Mercury. Temperatures at the surface reach 465C (860F). That's hot enough to melt lead! Now, I have a new situation: Brad and Joe studied atmospheric conditions on different planets of our solar system. Joe studied about Earth, while Brad studied more about Venus. Answer this question please: Which person learned about the planet with a thinner atmosphere?
++++++++
Answer: Joe
Problem: I can use this background: While people have been able to prevent certain viral diseases by vaccinations for many hundreds of years, the development of antiviral drugs to treat viral diseases is a relatively recent development. Antiviral drugs are medications used specifically for treating the symptoms of viral infections. The first antiviral drug was interferon , a substance that is naturally produced by certain immune cells when an infection is detected. Over the past twenty years the development of antiretroviral drugs (also known as antiretroviral therapy, or ART) has increased rapidly. This has been driven by the AIDS epidemic. Now, I have a new situation: Two pharma students read about antiviral and antibacterial drugs. Manny read about antiviral drugs, while George read about bacteria and antibacterial drugs. Answer this question please: Which student didn't read about antiretroviral therapy?

A: George
Problem: Given the question: I can use this background: Soil is well developed in the forest as suggested by the thick humus layers, rich diversity of large trees and animals that live there. In forests, precipitation exceeds evapotranspiration which results in an excess of water that percolates downward through the soil layers. Slow rates of decomposition leads to large amounts of fulvic acid, greatly enhancing chemical weathering. The downward percolation, in conjunction with chemical weathering leaches magnesium (Mg), iron (Fe), and aluminum (Al) from the soil and transports them downward, a process known as podzolization. This process leads to marked contrasts in the appearance and chemistry of the soil layers. Now, I have a new situation: Two brothers were land owners. Bill owned 40 acres of forest, , with very well developed soil. His brother Rick owned 40 acres of grasslands, with a poor soil. Rick decided to sell his land. Answer this question please: Which brother owned a land which showed an excess of water that percolates downward through the soil layers?
++++++++++++++++++++++++++++++++
The answer is:
Bill
input question: I can use this background: Electronegativities generally increase from left to right across a period. This is due to an increase in nuclear charge. Alkali metals have the lowest electronegativities, while halogens have the highest. Because most noble gases do not form compounds, they do not have electronegativities. Note that there is little variation among the transition metals. Electronegativities generally decrease from top to bottom within a group due to the larger atomic size. Now, I have a new situation: John was studying the periodic table. To make things easier for him he divided the table in different sections, section A, section B, section C, and section D. Section A elements are located at the left of the table, but section B elements are located at the right side of the table. Section C elements are located at the top, but section D elements are located at the bottom. Answer this question please: Which elements would have less electronegativities, section C or section D????
output answer: section D
input question: I can use this background: Pollutants also affect the atmosphere through their contribution to global warming. Global warming is an increase in the Earth's temperature. It is thought to be caused mostly by the increase of greenhouse gases like carbon dioxide. Greenhouse gases can be released by factories that burn fossil fuels. Over the past 20 years, burning fossil fuels has produced about three-quarters of the carbon dioxide from human activity. The rest of the carbon dioxide in the atmosphere is there because of deforestation, or cutting down trees ( Figure below ). Trees absorb carbon dioxide during cellular respiration, so when trees are cut down, they cannot remove carbon dioxide from the air. Now, I have a new situation: Tokyo recently had a large explosion in one of their largest steel manufacturing plants. The combination of heat, steel, and manufacturing materials released an extraordinary amount of carbon dioxide into the atmosphere. Meanwhile, Osaka has dramatically decreased the amount of carbon dioxide it releases through the installation of many public transportation projects and tree planting initiatives. Answer this question please: Which city, Tokyo or Osaka, will contribute more to global warming????
output answer:
Tokyo
