Problem: Given the question: I have a new situation: Most surfers used Wide beach because of the areas of shallow water, but some surfers were happy with Sandy beach, although the water was much deeper at the shore there. But I can use this background: When waves travel into areas of shallow water, they begin to be affected by the ocean bottom. The free orbital motion of the water is disrupted, and water particles in orbital motion no longer return to their original position. As the water becomes shallower, the swell becomes higher and steeper, ultimately assuming the familiar sharp-crested wave shape. After the wave breaks, it becomes a wave of translation and erosion of the ocean bottom intensifies. What is an answer for this question: Which beach experiences less disruption of the free orbital motion of the water?

The answer is:
Sandy

Problem: Given the question: I have a new situation: Two friends met after 20 years and had a beer together. Vlad was a geologist and studied earthquakes. Mort was a pedologist and studied soils. They had some interesting conversations that night. But I can use this background: Geologists study earthquake waves to "see" Earth's interior. Waves of energy radiate out from an earthquake's focus. These waves are called seismic waves ( Figure below ). Seismic waves go different speeds through different materials. They change speed when they go from one type of material to another. This causes them to bend. Some seismic waves do not travel through liquids or gases. They just stop. Scientists use information from seismic waves to understand what makes up the Earth's interior. What is an answer for this question: Which friend studied more about seismic waves bending?
++++++++++++++++++++++++++++++++
The answer is:
Vlad

Problem: Given the question: I have a new situation: When comparing village A from ten thousand years ago to village B from today, we reached the conclusion that today's villagers release much more carbon into the atmosphere by their activities. But I can use this background: Because of human activities, there is more carbon dioxide in the atmosphere today than in the past hundreds of thousands of years. Burning fossil fuels and has released great quantities of carbon dioxide into the atmosphere. Cutting forests and clearing land has also increased carbon dioxide into the atmosphere because these activities reduce the number of autotrophic organisms that use up carbon dioxide in photosynthesis. In addition, clearing often involves burning, which releases carbon dioxide that was previously stored in autotrophs. What is an answer for this question: Which village cut more forests?
++++++++++++++++++++++++++++++++
The answer is:
village B
