Question: Please answer correctly the following question related to the paragraph below. Which country causes more acid rain? Iran an Iraq are 2 neighbors. Iraq produces its electricity by burning fossil fuels, while Iran uses nuclear fission as its energy source. Hint: In the U.S., the majority of electricity is produced by burning coal or other fossil fuels. This causes air pollution, acid rain, and global warming. Fossil fuels are also limited and may eventually run out. Like fossil fuels, radioactive elements are limited. In fact, they are relatively rare, so they could run out sooner rather than later. On the other hand, nuclear fission does not release air pollution or cause the other environmental problems associated with burning fossil fuels. This is the major advantage of using nuclear fission as a source of energy.
Answer: Iraq

Question: Please answer correctly the following question related to the paragraph below. Which student studied less about rainfall? Two students at the Agricultural Institute studied pedology. Bob studied soil weathering, while Dan studied types of soil. Hint: 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.
Answer: Dan

Question: Please answer correctly the following question related to the paragraph below. Which lake was less dangerous to divers? 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. Hint: 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]
Answer:
Shallow
