Q: Given the background: Rainfall in an area is important because it influences the rate of weathering. More rain means that more rainwater passes through the soil. The rainwater reacts chemically with the particles. The top layers of soil are in contact with the freshest water, so reactions are greatest there. High rainfall increases the amount of rock that experiences chemical reactions. High rainfall may also carry material away. This means that new surfaces are exposed. This increases the rate of weathering. and the situation: Rob is an environmental scientist. He is looking at two samples of soil, sample A and sample B. Sample A is from Amazon Rain-forest, where they get one of the highest rainfall in the world. Sample B is from the Atacama Desert, where they get one of the lowest rainfall in the world. He needs to determine the properties of these samples. Answer the following question: Which sample would show decreased rate of weathering, sample A or sample B?
A: sample B

Q: Given the background: This individual monetary gain creates an increase in the overall economic productivity of a country. Girls are underrepresented in schooling, meaning that investments aimed specifically at educating women should produce bigger dividends.[9] Although investment in women's education is not present everywhere, David Dollar and Roberta Gatti have presented findings that show that this decision, along with other failures to invest in women are not "an efficient economic choice for developing countries" and that "countries that under-invest grow more slowly."[3] Looking holistically at the opportunity cost of not investing in girls, the total missed GDP growth is between 1.2% and 1.5%.[10] When looking at different regions, it is estimated that 0.40.9% of the difference in GDP growth is accounted for solely by differences in the gender gap in education.[1] The effect of the educational gender gap is more pronounced when a country is only moderately poor.[3] Thus the incentive to invest in women goes up as a country moves out of extreme poverty.[3] and the situation: Ethiopia and Sudan are two neighboring countries where extreme poverty can be seen. Still Ethiopia has pushed for women's education in the last decade. Sudan has largely failed in investing on women's education. Elsewhere in Africa, the country of Botswana has just overcome extreme poverty, thanks to vast mineral deposits. But they invested on women's education. Answer the following question: Which country would expect slower economic growth, Ethiopia or Sudan?
A: Sudan

Q: Given the background: Shown in the Figure below is a cylinder of gas on the left that is at room temperature (300 K). On the right, the cylinder has been heated until the Kelvin temperature has doubled to 600 K. The kinetic energy of the gas molecules increases, so collisions with the walls of the container are now more forceful than they were before. As a result, the pressure of the gas doubles. Decreasing the temperature would have the opposite effect, and the pressure of an enclosed gas would decrease. and the situation: In a laboratory, Marcus is working with two identical containers of the same amount of gas inside them. For his next experiment, he needs these containers to be different temperatures. He takes container X and puts it in the refrigerator, and he leaves container Y out on the table. One hour later, he comes back and takes container X out of the refrigerator so he can now begin his experiment. Answer the following question: Is the pressure in container X higher or lower than container Y?
A: lower

Q: Given the 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] and the situation: Deep lake presents geothermal activity, while Shallow lake has mixing of saline water with fresh water. Deep lake had more instances of divers having problems because of thermoclines. Answer the following question: Which lake has fewer thermoclines?
A:
Shallow lake
