Q: I can use this background: Thermoclines, or sudden changes in temperature. Where the air temperature is higher than the water temperature, shallow water may be warmed by the air and the sunlight but deeper water remains cold resulting in a lowering of temperature as the diver descends. This temperature change may be concentrated over a small vertical interval, when it is called a thermocline.[3][4] Where cold, fresh water enters a warmer sea the fresh water may float over the denser saline water, so the temperature rises as the diver descends.[3] In lakes exposed to geothermal activity, the temperature of the deeper water may be warmer than the surface water. This will usually lead to convection currents.[3] Now, I have a new situation: The underwater fishing teams picked their spots early. Team Bob went at the mouth of the river, where the freshwater met the salty seawater in the hope that more turbidity from the river and more nutrients will attract more fish. Team Dan went south where they knew there was less of a thermocline, so they could catch fish without taking risks. Answer this question please: Which team had less chances to catch fish?
A: Dan

Q: I can use this 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). Now, I have a new situation: 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. Answer this question please: Which planet didn't record parallel increases in concentration of carbon dioxide and average global temperature?
A: Moon

Q: I can use this background: Millions of people in the world jog for exercise. For the most part, jogging can be a healthy way to stay fit. However, problems can also develop for those who jog in the heat. Excessive sweating can lead to electrolyte loss that could be life-threatening. Early symptoms of electrolyte deficiency can include nausea, fatugue, and dizziness. If not treated, individuals can experience muscle weakness and increased heart rate (which could lead to a heart attack). Many sports drinks can be consumed to restore electrolytes quickly in the body. Now, I have a new situation: The Jones family went jogging last Saturday. The weather was great for running, a bit chilly. The Brown family went jogging on Sunday and the weather was hot and humid, so it was tough for them, plus they forgot their Gatorade at home. Answer this question please: Which family was more exposed to excessive sweating?
A: Brown

Q: I can use this background: 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. Now, I have a new situation: Russian research spent most of their time in Antarctica to study the loss of ozone in the atmosphere. The Canadian team went north of the Polar Circle, close to the North Pole to do the same thing. They spent several months there. The Canadian team didn't find any ozone holes at the North Pole. Answer this question please: Which team was more exposed to skin cancers?
A:
Russian
