Problem: 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! Paragraph: Brad and Joe studied atmospheric conditions on different planets of our solar system. Joe studied about Earth, while Brad studied more about Venus. Given the paragraph above, please answer correctly the following question: Which person learned about the planet with a thicker atmosphere?

A: Brad

Problem: Background: Another example of incomplete dominance is with sickle cell anemia, a disease in which a blood protein called hemoglobin is produced incorrectly. This causes the red blood cells to have a sickle shape, making it difficult for these misshapen cells to pass through the smallest blood vessels. A person that is homozygous recessive ( ss ) for the sickle cell trait will have red blood cells that all have the incorrect hemoglobin. A person who is homozygous dominant ( SS ) will have normal red blood cells. Paragraph: Two sisters named Mary and Ann went in for a blood test and found out that Mary had sickle cell anemia. Ann was normal. Given the paragraph above, please answer correctly the following question: Which sister wasn't homozygous dominant?

A: Mary

Problem: Background: Current Situation : Currently the heating effect of extra greenhouse gases (since the start of the industrial revolution) is equal to about . Thus the recent period has recorded parallel increases in concentration of carbon dioxide and average global temperature. As more greenhouse gases are put into the atmosphere the temperature will increase further. There are certain effects of a warmer Earth (discussed more in optional section), which could accelerate the process, even if no more greenhouse gases are put into the atmosphere (an unlikely prospect for the foreseeable future). Paragraph: Moon and Earth were two sister planets, both inhabited by humans. People of Earth released large quantities of greenhouse gases into the atmosphere over the last decades, while Moon people were taking good care of their planet and the environment. Given the paragraph above, please answer correctly the following question: Which planet observed an increased average global temperature?

A: Earth

Problem: Background: Carbon dioxide is the most significant long-lived greenhouse gas in Earth's atmosphere. Since the Industrial Revolution anthropogenic emissions primarily from use of fossil fuels and deforestation have rapidly increased its concentration in the atmosphere, leading to global warming. Carbon dioxide also causes ocean acidification because it dissolves in water to form carbonic acid. Paragraph: China used alternative fuels to generate electricity, while Mongolia burned lots of fossil fuels. There were frequent debates between the two countries on this matter. Given the paragraph above, please answer correctly the following question: Which country released more carbon dioxide into the atmosphere?

A:
Mongolia
