Two groups of students went to the forest to explore nature and learn botany. Group D had some people experiencing mild allergy symptoms, and group C had a few folks with severe allergy symptoms, so they had to call the ambulance asap. Given the paragraph above, please answer correctly the following question: Which group had more people sneezing a lot? Hint: Allergy symptoms can range from mild to severe. Mild symptoms might include itchy eyes, sneezing, and a runny nose. Severe symptoms can cause difficulty breathing, which may be life threatening. Keep in mind that it is the immune system and not the allergen that causes the allergy symptoms. Allergy symptoms can be treated with medications such as antihistamines. Severe allergic reactions may require an injection of the hormone epinephrine. These treatments lessen or counter the immune system's response.
Ans: Group D

Thanks to environmental initiatives, Quebec has grown a large number of forests recently that are densely populated with tall trees. At the same time, Ottawa has been cutting down large numbers of trees in their forests and clearing the land to make room for housing developments and new construction sites. Given the paragraph above, please answer correctly the following question: Which city, Quebec or Ottawa, has released less carbon dioxide through their actions? Hint: Because of human activities, there is more carbon dioxide in the atmosphere today than in the past hundreds of thousands of years. Burning fossil fuels and has released great quantities of carbon dioxide into the atmosphere. Cutting forests and clearing land has also increased carbon dioxide into the atmosphere because these activities reduce the number of autotrophic organisms that use up carbon dioxide in photosynthesis. In addition, clearing often involves burning, which releases carbon dioxide that was previously stored in autotrophs.
Ans: Quebec

John was studying the plate tectonics of earth. He specifically selected two locations, location A and location B. He noticed that location A had lot of plate tectonics activities, but location B didn't have much of that. He wondered how that would make difference in those locations' characteristics. Given the paragraph above, please answer correctly the following question: In location B would seafloor more likely or less likely form than in location A? Hint: Earth is a restless planet. Heat in the Earth's interior causes giant plates of crust to move around on the surface. The crashing and smashing of these plates leads to nearly all of the geological activity we see. Plate collisions bring us volcanoes and earthquakes, mountain ranges, and many resources. Seafloor forms as plates move apart. Some of Earth's most beautiful landscapes come from plate tectonics. The Grand Tetons in Wyoming rose up as the Farallon Plate sunk beneath the North American Plate during the Laramide orogeny.
Ans: less likely

Iceland and Ireland both used agriculture as a the main component of their economies. Ireland used lots of fertilizer and had big environmental problems as a result. Iceland does a lot of greenhouse agriculture using geothermal energy, so it is more protective towards the environment. Given the paragraph above, please answer correctly the following question: Which country caused fewer decomposers to break down dead algae? Hint: Rain dissolves fertilizer in the soil. Runoff carries it away. The fertilizer ends up in bodies of water, from ponds to oceans. Nitrogen is a fertilizer in the water. Since there is a lot of nitrogen, it causes algae to grow out of control. Pictured below is a pond covered with algae ( Figure below ). Algae use up carbon dioxide in the water. After the algae die, decomposers break down the dead tissue. The decomposers use up all the oxygen in the water. This creates a dead zone. A dead zone is an area in a body of water where nothing grows because there is too little oxygen. There is a large dead zone in the Gulf of Mexico ( Figure below ). The U.S. states outlined on the map have rivers that drain into the Gulf of Mexico. The rivers drain vast agricultural lands. The water carries fertilizer from these areas into the Gulf.
Ans: Iceland
