Q: I can use this background: Although some lipids in the diet are essential, excess dietary lipids can be harmful. Because lipids are very high in energy, eating too many may lead to unhealthy weight gain. A high-fat diet may also increase lipid levels in the blood. This, in turn, can increase the risk for health problems such as cardiovascular disease. The dietary lipids of most concern are saturated fatty acids, trans fats, and cholesterol. For example, cholesterol is the lipid mainly responsible for narrowing arteries and causing the disease atherosclerosis. Now, I have a new situation: Two groups of people were part of a science study. Group A ate lots of fats(lipids), while Group B had a more balanced diet with few fats. Group A gained a lot of weight over the course of the 6 month study. Answer this question please: Which group had more chances of developing cardiovascular disease?
A: Group A

Q: I can use this background: Hepatitis viruses can develop into a chronic viral infection that leads to liver cancer. Infection by human T-lymphotropic virus can lead to tropical spastic paraparesis and adult T-cell leukaemia. Human papillomaviruses are an established cause of cancers of cervix, skin, anus, and penis. Within the Herpesviridae, Kaposi's sarcoma-associated herpesvirus causes Kaposi's sarcoma and body-cavity lymphoma, and EpsteinBarr virus causes Burkitt's lymphoma, Hodgkin's lymphoma, B lymphoproliferative disorder, and nasopharyngeal carcinoma. Merkel cell polyomavirus closely related to SV40 and mouse polyomaviruses that have been used as animal models for cancer viruses for over 50 years. Now, I have a new situation: Two medical students had to study about viruses that cause cancers in humans. Brady studied about hepatitis viruses, while Dean studied about human papillomaviruses and Herpesviridae. Answer this question please: Which student read more about cancers of the skin?
A: Dean

Q: I can use this background: Animals and some bacteria and fungi carry out lactic acid fermentation. Lactic acid is a waste product of this process. Our muscles perform lactic acid fermentation during strenuous exercise, since oxygen cannot be delivered to the muscles quickly enough. The buildup of lactic acid is believed to make your muscles sore after exercise. Bacteria that produce lactic acid are used to make cheese and yogurt. The lactic acid causes the proteins in milk to thicken. Lactic acid also causes tooth decay, because bacteria use the sugars in your mouth for energy. Now, I have a new situation: Two groups of microbiology students studied about the fermentation process. Group A studied about alcoholic and acetic fermentation, while group B studied about lactic fermentation. Answer this question please: Which group learned more about fungi?
A: group B

Q: I can use this background: It mutates DNA. The Chernobyl disaster was a nuclear accident that occurred on April 26, 1986. It is considered the worst nuclear power plant accident in history. A Russian publication concludes that 985,000 excess cancers occurred between 1986 and 2004 as a result of radioactive contamination. The 2011 report of the European Committee on Radiation Risk calculates a total of 1.4 million excess cancers occurred as a result of this contamination. Now, I have a new situation: A Power plant meltdown near the town of Jeskai causes a large amount of radiation to leak into the surrounding area. While some evacuated many people just assumed the power plant should be far enough away to not really affect them. . Answer this question please: Will excess exposure to radiation increase or decrease a parsons chance of getting cancer?
A:
increase
