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. Now, 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. Answer this question please: Which friend studied less about waves of energy radiating out from an earthquake's focus?
Ans: Mort

I can use this background: Hemophilia is the name of a group of hereditary diseases that affect the body's ability to control blood clotting. Hemophilia is caused by a lack of clotting factors in the blood. Clotting factors are normally released by platelets. Since people with hemophilia cannot produce clots, any cut can put a person at risk of bleeding to death. The risk of internal bleeding is also increased in hemophilia, especially into muscles and joints. This disease affected the royal families of Europe. Now, I have a new situation: Two cousins went for a blood test. Tim found out he had hemophilia, while John was normal. Tim had to start taking medication. Answer this question please: Which cousin has a greater chance of bleeding to death?
Ans: Tim

I can use this background: Cancer is a disease that causes cells to divide out of control. Normally, the body has systems that prevent cells from dividing out of control. But in the case of cancer, these systems fail. Cancer is usually caused by mutations. Mutations are random errors in genes. Mutations that lead to cancer usually happen to genes that control the cell cycle. Because of the mutations, abnormal cells divide uncontrollably. This often leads to the development of a tumor. A tumor is a mass of abnormal tissue. As a tumor grows, it may harm normal tissues around it. Anything that can cause cancer is called a carcinogen . Carcinogens may be pathogens, chemicals, or radiation. Now, I have a new situation: Two sisters went to the doctor to get screened for cancer. Lisa had cancer, while her sister Beth didn't. Lisa was terrified, but her sister comforted her. Answer this question please: Which sister didn't have a disease caused by random errors in genes?
Ans: Beth

I can use this background: When humans dig up and use fossil fuels, we have an impact on the carbon cycle ( Figure below ). This carbon is not recycled until it is used by humans. The burning of fossil fuels releases more carbon dioxide into the atmosphere than is used by photosynthesis. So, there is more carbon dioxide entering the atmosphere than is coming out of it. Carbon dioxide is known as a greenhouse gas , since it lets in light energy but does not let heat escape, much like the panes of a greenhouse. The increase of greenhouse gasses in the atmosphere is contributing to a global rise in Earth's temperature, known as global warming or global climate change. Now, I have a new situation: India decided to use fossil fuels to produce their electricity, and Nepal decided to go renewable and use only hydro power to produce their electricity. Answer this question please: Which country had less of an impact on the carbon cycle?
Ans: Nepal
