Problem: I read this background article the other day: Unfortunately, the layer of good ozone is being destroyed by air pollution. The chief culprits are chlorine and bromine gases. They are released in aerosol sprays, coolants, and other products. Loss of ozone has created an ozone hole over Antarctica. Ozone depletion results in higher levels of UV radiation reaching Earth. In humans, this increases skin cancers and eye cataracts. It also disturbs the nitrogen cycle, kills plankton, and disrupts ocean food webs. The total loss of the ozone layer would be devastating to most life. Its rate of loss has slowed with restrictions on pollutants, but it is still at risk. I am facing a new situation today: Two neighboring habitable planets from the same solar system, planet U and planet N, had Earth-like atmospheres. The inhabitants of planet U destroyed the ozone layer by their actions, while their neighboring planet N didn't. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which planet released less bromine gas in their atmosphere?

A: planet N
Problem: Given the question: I read this background article the other day: When waves travel into areas of shallow water, they begin to be affected by the ocean bottom. The free orbital motion of the water is disrupted, and water particles in orbital motion no longer return to their original position. As the water becomes shallower, the swell becomes higher and steeper, ultimately assuming the familiar sharp-crested wave shape. After the wave breaks, it becomes a wave of translation and erosion of the ocean bottom intensifies. I am facing a new situation today: Two neighboring gulfs had different geographical features. South gulf has shallow water and is wider, while North gulf is quite deep. Both gulfs are exposed to intense wave activity throughout the year. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which gulf experiences more erosion on the ocean bottom?
++++++++++++++++++++++++++++++++
The answer is:
South
input question: I read this background article the other day: 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. I am facing a new situation today: Two sisters named Mary and Ann went in for a blood test and found out that Mary had sickle cell anemia. Ann was normal. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which sister had a disease in which a blood protein called hemoglobin is produced incorrectly????
output answer: Mary
I read this background article the other day: A period of very low rainfall occurred while the Grants were on the islands. The drought resulted in fewer seeds for the finches to eat. Birds with smaller beaks could eat only the smaller seeds. Birds with bigger beaks were better off. They could eat seeds of all sizes. Therefore, there was more food available to them. Many of the small-beaked birds died in the drought. More of the big-beaked birds survived and reproduced. Within just a couple of years, the average beak size in the finches increased. This was clearly evolution by natural selection. I am facing a new situation today: Two bird islands in the Atlantic Ocean had very different climate changes during the last 5 years. Bone island experienced drought, while Finch island experienced flooding. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which island had more of the big-beaked birds survive?
----
Answer: Bone
Q: I read this background article the other day: As for the public health or food safety concern, organic foods are intended to be healthy, free of contaminations and free from agents that could cause human diseases. Organic milk is meant to have no chemical residues to consumers, and the restrictions on the use of antibiotics and chemicals in organic food production has the purpose to accomplish this goal. Although dairy cows in both organic and conventional farming practices can be exposed to pathogens, it has been shown that, because antibiotics are not permitted as a preventative measure in organic practices, there are far fewer antibiotic resistant pathogens on organic farms. This dramatically increases the efficacy of antibiotics when/if they are necessary. I am facing a new situation today: Two farmers sold their produce and milk on a large nearby market. John practiced organic farming and also produced organic milk, while Danny sold non-organic produce and milk. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which farmer sold more healthy and safe foods?
A: John
[Q]: I read this background article the other day: The first evidence of baking occurred when humans took wild grass grains, soaked them in water, and mixed everything together, mashing it into a kind of slippery and wet broth-like paste.[3] The paste was cooked by pouring it onto a flat, hot rock, resulting in a bread-like substance. Later, when humans mastered fire, the paste was roasted on hot embers, which made bread-making easier, as it could now be made any time fire was created. The world's oldest oven was discovered in Croatia in 2014 dating back 6500 years ago. The Ancient Egyptians baked bread using yeast, which they had previously been using to brew beer.[4] Bread baking began in Ancient Greece around 600 BC, leading to the invention of enclosed ovens.[4] "Ovens and worktables have been discovered in archaeological digs from Turkey (Hacilar) to Palestine (Jericho) and date back to 5600 BC."[5] I am facing a new situation today: Students learned about bread making in school, and were fascinated by the history of bread. They learned ancient bread making techniques that they experimented with later on.Group A experimented with Egyptian and Greek techniques, while group B made it the Croatian and the Turkish way. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which people used brewer's yeast to make bread?
****
[A]:
Egyptian
