input: Please answer the following: I have a new situation: Two colleagues gave blood for an emergency. Ned got infected with HIV because they re-used a needle. His friend Nate was not infected. But I can use this background: The Human Immunodeficiency Virus ( HIV ) is the virus that causes Acquired Immunodeficiency Syndrome ( AIDS ). Most researchers believe that the HIV originated in sub-Saharan Africa during the 20th century. HIV is transmitted by sexual contact and by contact with infected bodily fluids, such as blood, semen, breast milk, and vaginal secretions. It is also passed from mother to fetus. HIV is now a pandemic , with an estimated (as of 2008) 38.6 million people now living with the disease worldwide. It is estimated that AIDS has killed more than 25 million people since it was first recognized in 1981. For further information about HIV/AIDS, see the CDC (Centers for Disease Control and Prevention) web site at http://www.cdc.gov/hiv/resources/factsheets/ . What is an answer for this question: Which colleague had a virus that originated in sub-Saharan Africa?

Please answer this: I have a new situation: The biologists found out that the Indian Ocean had a lower water pH than it did a decade ago, and it became acidic. The water in the Arctic ocean still had a neutral to basic pH. But I can use this background: Ocean acidification occurs when excess carbon dioxide in the atmosphere causes the oceans to become acidic. Burning fossil fuels has led to an increase in carbon dioxide in the atmosphere. This carbon dioxide is then absorbed by the oceans, which lowers the pH of the water. Ocean acidification can kill corals and shellfish. It may also cause marine organisms to reproduce less, which could harm other organisms in the food chain. As a result, there also may be fewer marine organisms for humans to consume. What is an answer for this question: Which ocean had more instances of marine organisms reproducing less?

Answer: Indian
Problem: I have a new situation: Mary and Ben went in for a blood test. Ben had high cholesterol, so the Doctor recommended him to lower it. Mary had normal cholesterol levels. But I can use this background: Cholesterol can't dissolve in the blood. It has to be transported to and from the cells by carriers called lipoproteins. Low-density lipoprotein, or LDL, is known as "bad" cholesterol. High-density lipoprotein (HDL) is known as good cholesterol. When too much LDL cholesterol circulates in the blood, it can slowly build up in the inner walls of the arteries that feed the heart and brain. Together with other substances, it can form plaque, and lead to atherosclerosis. If a clot forms and blocks a narrowed artery, a heart attack or stroke can result. Cholesterol comes from the food you eat as well as being made by the body. To lower bad cholesterol, a diet low in saturated fat and dietary cholesterol should be followed. Regular aerobic exercise also lowers LDL cholesterol and increases HDL cholesterol. What is an answer for this question: Which person had lower levels of HDL?

A: Ben
Problem: Given the question: I have a new situation: Manny and Dean were two classmates. They had to prepare for a school project so they decided to learn about animals. Manny studied animal communication, while Dean studied animal feeding patterns and nutrition. But I can use this background: Communication is any way that animals share information. Many animals live in social groups. For these animals, being able to communicate is essential. Communicating increases the ability of group members to cooperate and avoid conflict. Communication may help animals work together to find food and defend themselves from predators. It also helps them find mates and care for their offspring. In addition, communication helps adult animals teach the next generation learned behaviors. Therefore, communication generally improves the chances of animals surviving and reproducing. What is an answer for this question: Which student learned less about animals working together to find food?

Dean
input question: I have a new situation: Two brothers went to the doctor for their yearly examination. Liam found out he has high cholesterol, while Rudy found out his triglycerides and cholesterol are within normal parameters. But I can use this background: Cholesterol has been implicated in heart disease for decades. Atherosclerosis is a disorder of the arteries in which cholesterol and other materials are deposited on the interior of the arterial wall. These deposits lead to the formation of plaques that can restrict or even block the flow of blood through these blood vessels (see Figure below ). A decrease in the flow of blood can lead to high blood pressure and a lowered oxygen supply to the heart muscle. A complete blockage of blood flow to parts of the heart (a heart attack) can cause significant damage due to oxygen deprivation, in some cases leading to death. What is an answer for this question: Which brother was less at risk for atherosclerosis????
output answer: Rudy
input question: I have a new situation: Danny started weight lifting two years ago, he wanted to be bigger. His brother Arnie preferred athletic competitions such as running, so he became a runner. But I can use this background: In exercises such as weight lifting, skeletal muscle contracts against a resisting force (see Figure below ). Using skeletal muscle in this way increases its size and strength. In exercises such as running, the cardiac muscle contracts faster and the heart pumps more blood. Using cardiac muscle in this way increases its strength and efficiency. Continued exercise is necessary to maintain bigger, stronger muscles. If you don't use a muscle, it will get smaller and weakerso use it or lose it. What is an answer for this question: Which brother gradually increased the size of his muscles????
output answer:
Danny
