Q: 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. It's rate of loss has slowed with restrictions on pollutants, but it is still at risk. I am facing a new situation today: Big continent used more air polluting substances, while Small continent was very protective towards the environment. Big continent got a hole in its ozone layer as a consequence of their actions. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which continent used more chlorine gasses?
A: Big
Question: I read this background article the other day: At birth, a rattlesnake hatchling has only a small button or 'primordial rattle' which is firmly attached to the tip of the tail.[13] The first segment is added when the hatchling sheds its skin for the first time.[14] A new section is added each time the skin is shed until a rattle is formed. The rattle grows as the snake ages but segments are also prone to breaking off and hence the length of a rattle is not a reliable indicator of the age of a snake.[15] I am facing a new situation today: Dan found three rattle snakes: one only had one rattle, the second snake had 4 rattles and the third snake had seven rattles on its tail. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which snake had more segments, the first or the second snake Dan found?
Answer: the second
[Q]: I read this background article the other day: Almost all earthquakes occur at plate boundaries. All types of plate boundaries have earthquakes. Convection within the Earth causes the plates to move. As the plates move, stresses build. When the stresses build too much, the rocks break. The break releases the energy that was stored in the rocks. The sudden release of energy creates an earthquake. During an earthquake the rocks usually move several centimeters or rarely as much as a few meters. Elastic rebound theory describes how earthquakes occur ( Figure below ). I am facing a new situation today: Two sister cities were both situated on plate boundaries, close to volcanoes, on different continents. Red city was 10 miles from a volcano, while Tree city was 60 miles away. Red city experienced many earthquakes, Tree city few and far between. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which city experienced more stress build up within the rocks?
****
[A]: Red
input: Please answer the following: I read this background article the other day: Quicksand forms in saturated loose sand when the sand is suddenly agitated. When water in the sand cannot escape, it creates a liquefied soil that loses strength and cannot support weight. Quicksand can form in standing water or in upwards flowing water (as from an artesian spring). In the case of upwards flowing water, forces oppose the force of gravity and suspend the soil particles. The saturated sediment may appear quite solid until a sudden change in pressure or shock initiates liquefaction. This causes the sand to form a suspension and lose strength. The cushioning of water gives quicksand, and other liquefied sediments, a spongy, fluid-like texture. Objects in liquefied sand sink to the level at which the weight of the object is equal to the weight of the displaced soil/water mix and the submerged object floats due to its buoyancy. I am facing a new situation today: Rob is competing in a cross country race. After running about a mile he reached a place with two signs, sign A and sign B. Sign A says that it's a quicksand. But sign B says that it's not a quicksand. He has to decide which way to go. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: In which way Rob would not sink, sign A or sign B?
++++++++++
output: sign B
Please answer this: I read this background article the other day: Common foodborne viruses include norovirus and hepatitis A virus. Norovirus, which causes inflammation of the stomach and intestines, has been a recent issue on cruise ships, infecting hundreds of passengers and crew on certain voyages. Hepatitis A causes inflammation of the liver, which is treated with rest and diet changes. Parasites are tiny organisms that live inside another organism. Giardia is a parasite spread through water contaminated with the stools of people or animals who are infected. Food preparers who are infected with parasites can also contaminate food if they do not thoroughly wash their hands after using the bathroom and before handling food. Trichinella is a type of roundworm parasite. People may be infected with this parasite by consuming raw or undercooked pork or wild game. I am facing a new situation today: Two groups of tourists went on two different cruise ships Group J had some members contract Norovirus and hepatitis A, while group K got many cases of giardia and trichinella infections. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which group had people treated with rest and diet changes?
++++++++
Answer: Group J
Question: I read this background article the other day: The lungs of mammals are unique in having alveoli . These are tiny, sac-like structures. Each alveolus is surrounded by a network of very small blood vessels (see Figure below ). Because there are millions of alveoli in each lung, they greatly increase the surface area for gas exchange between the lungs and bloodstream. Human lungs, for example, contain about 300 million alveoli. They give the lungs a total surface area for gas exchange of up to 90 square meters (968 square feet). That's about as much surface area as one side of a volleyball court! I am facing a new situation today: Two six graders learned about the lives of animals. Lori learned more about fish, while Dan learned more about mammals. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which student learned more about gas exchange between the lungs and bloodstream?
Answer:
Dan
