Problem: Given the question: Given the background: When humans dig up and use fossil fuels, we have an impact on the carbon cycle ( Figure below ). This carbon is not recycled until it is used by humans. The burning of fossil fuels releases more carbon dioxide into the atmosphere than is used by photosynthesis. So, there is more carbon dioxide entering the atmosphere than is coming out of it. Carbon dioxide is known as a greenhouse gas , since it lets in light energy but does not let heat escape, much like the panes of a greenhouse. The increase of greenhouse gasses in the atmosphere is contributing to a global rise in Earth’s temperature, known as global warming or global climate change.  and the situation: India decided to use fossil fuels to produce their electricity, and Nepal decided to go renewable and use only hydro power to produce their electricity.  Answer the following question: Which country released more carbon dioxide into the atmosphere?
++++++++++++++++++++++++++++++++
The answer is:
India


Problem: Given the question: Given the background: 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.  and the situation: It is currently spring time where Jonathan lives, and there is a high amount of pollen in the air. When Jonathan goes outside his eyes start to water and become itchy, and he can't stop sneezing. Jonathan's brother, Thomas, was recently invited to a seafood dinner.  Thomas decided to eat some shellfish, and a short while later he felt like his throat was closing up and it was becoming difficult to breathe.  Answer the following question: Who will less likely require an injection of epinephrine?
++++++++++++++++++++++++++++++++
The answer is:
Jonathan


Problem: Given the question: Given the background: Beginning in the late 1970’s, ozone depletion was recognized as a significant environmental issue. The most dramatic decrease in ozone occurs seasonally over the continent of Antarctica. The size and duration of the ozone hole steadily increased, with the largest hole recorded in 2006. Fortunately, most countries have recognized the danger of CFCs and dramatically curtailed their use in recent years. It is hoped that ozone depletion will slow and that the ozone layer may eventually be restored to its earlier levels.  and the situation: Ben and Harry were studying about the climatic history of Earth. Ben was more attracted to learning about early Ice Ages, while Harry was curious about the Earth atmosphere and read about ozone depletion and its consequences.  Answer the following question: Which person learned less about the most dramatic decrease in ozone?
++++++++++++++++++++++++++++++++
The answer is:

Ben
