Question: Problem: Given the question: I can use this background: The epidermis also contains melanocytes, which are cells that produce melanin. Melanin is the brownish pigment that gives skin much of its color. Everyone has about the same number of melanocytes, but the melanocytes of people with darker skin produce more melanin. The amount of melanin produced is determined by heredity and exposure to UV light, which increases melanin output. Exposure to UV light also stimulates the skin to produce vitamin D. Because melanin blocks UV light from penetrating the skin, people with darker skin may be at greater risk of vitamin D deficiency.  Now, I have a new situation: Jacob has lived in a city in Sweden for most of his life. His favorite hobbies are reading and playing videogames so he rarely goes outside. Even as a kid, he almost never played outside and instead was in his house most of the time. Martin lives in the middle of the Sahara desert in a small town. The sun almost never stops beating down on Martin during the day and it's hard to find shade where he lives.  Answer this question please: Who has darker skin?

The answer is:
Martin


Problem: Given the question: 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 taken a less cautious approach?
++++++++++++++++++++++++++++++++
The answer is:
Bob


Problem: Given the question: I can use this background: The Laffer curve depicts the amount of government revenue as a function of the rate of taxation. It shows that for a tax rate above a certain critical rate, government revenue starts decreasing as the tax rate rises, as a consequence of a decline in labour supply. This theory supports that, if the tax rate is above that critical point, a decrease in the tax rate should imply a rise in labour supply that in turn would lead to an increase in government revenue.  Now, I have a new situation: After the second world war Germany and France took two different policies in respect to taxation. After the war Germany, then West Germany, has mostly elected pro-capitalist governments. As a consequence, Germany implemented tax rate below the critical rate. But France took the other way. Their mostly pro-socialist governments implemented tax rate above the critical rate. As a result, businesses had to make informed decisions while doing business in these countries.  Answer this question please: Which country would have lower labor supply in response to their taxation?

The answer is:

Answer: France
