Question: 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. Paragraph: Long island was full of people and they used all their natural resources and burned fossil fuels while Snail island protected the environment and had fewer people living there. Given the paragraph above, please answer correctly the following question: Which island contributed less to an increase in greenhouse gasses?
Answer: Snail

Question: Background: So much rain falling so fast causes some of the damage from a hurricane. But a lot of the damage is caused by storm surge. Storm surge is very high water located in the low pressure eye of the hurricane. The very low pressure of the eye allows the water level to rise above normal sea level. Storm surge can cause flooding when it reaches land ( Figure below ). High winds do a great deal of damage in hurricanes. High winds can also create very big waves. If the large waves are atop a storm surge, the high water can flood the shore. If the storm happens to occur at high tide, the water will rise even higher. Paragraph: Two coastal cities, Dune and Shore, got a Hurricane warning. The hurricane hit Dune city, but missed Shore city by 50 miles. The damage was horrendous. Given the paragraph above, please answer correctly the following question: Which city experienced less flooding reaching land?
Answer: Shore

Question: Background: A mycorrhiza (Greek for "fungus roots") is a symbiotic association between a fungus and the roots of a plant. In a mycorrhizal association, the fungus may colonize the roots of a host plant by either growing directly into the root cells, or by growing around the root cells. This association provides the fungus with relatively constant and direct access to glucose, which the plant produces by photosynthesis. The mycelia of the fungi increase the surface area of the plant's root system. The larger surface area improves water and mineral nutrient absorption from the soil. Paragraph: Two mycologists were studying fungi. Jim studied more about wood eating mushrooms and gourmet mushrooms, while George decided to study more about mycorrhiza, and its benefits for humans. Given the paragraph above, please answer correctly the following question: Which mycologist learned more about a symbiotic association between a fungus and the roots of a plant?
Answer:
George
