input: Please answer the following: I read this background article the other day: While people have been able to prevent certain viral diseases by vaccinations for many hundreds of years, the development of antiviral drugs to treat viral diseases is a relatively recent development. Antiviral drugs are medications used specifically for treating the symptoms of viral infections. The first antiviral drug was interferon , a substance that is naturally produced by certain immune cells when an infection is detected. Over the past twenty years the development of antiretroviral drugs (also known as antiretroviral therapy, or ART) has increased rapidly. This has been driven by the AIDS epidemic. I am facing a new situation today: Two friends had different diseases. Nigel was more prone to viral infections, so one day he got infected with the HIV virus. Manny had contracted some sort of bacterial infection. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which friend received more ART?

Please answer this: I read this background article the other day: A mycorrhiza (Greek for "fungus roots") is a symbiotic association between a fungus and the roots of a plant. In a mycorrhizal association, the fungus may colonize the roots of a host plant by either growing directly into the root cells, or by growing around the root cells. This association provides the fungus with relatively constant and direct access to glucose, which the plant produces by photosynthesis. The mycelia of the fungi increase the surface area of the plant's root system. The larger surface area improves water and mineral nutrient absorption from the soil. I am facing a new situation today: Two friends studied permaculture together. Bill studied about mycorrhiza, while Red studied about hugel kultur. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which friend learned more about glucose?

Answer: Bill
Problem: I read this background article the other day: 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. I am facing a new situation today: Manny and Joe checked their cholesterol levels. Joe found out that his cholesterol levels were within normal parameters, while Manny had very high cholesterol levels and was recommended some lifestyle changes. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which person was at a lower risk of experiencing a heart attack?

A: Joe
Problem: Given the question: I read this background article the other day: Compared to conventional milk production, organic milk production tends to have lower eutrophication potential per ton of milk or per hectare of farmland, because it potentially reduces leaching of nitrates (NO3) and phosphates (PO4) due to lower fertilizer application rates. Because organic milk production reduces pesticides utilization, it increases land use per ton of milk due to decreased crop yields per hectare. Mainly due to the lower level of concentrates given to cows in organic herds, organic dairy farms generally produce less milk per cow than conventional dairy farms. Because of the increased use of roughage and the, on-average, lower milk production level per cow, some research has connected organic milk production with increases in the emission of methane.Animal welfare issues vary among dairy farms and are not necessarily related to the way of producing milk (organically or conventionally). I am facing a new situation today: Peet farm was supplying a nearby city with organic milk. Toad farm was a competitor on the same market, but they didn't produce organic milk, they used conventional agricultural methods. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which farm leached fewer nitrates (NO3)?

The answer is:
Peet
input question: I read this background article the other day: 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. I am facing a new situation today: John was studying about the history of Sahara desert. He was amazed to find that ten thousand years ago there were plenty of rainfall in that region. He labeled that era as era A. Then he found that rainfall deceased in the region about eight thousand years ago. He labeled that era as era B. He was wondering how that change in rainfall might have helped emerge the Egyptian civilization. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which era would see lower rate of weathering, era A or era B????
output answer: era B
input question: I read this background article the other day: The lungs of mammals are unique in having alveoli . These are tiny, sac-like structures. Each alveolus is surrounded by a network of very small blood vessels (see Figure below ). Because there are millions of alveoli in each lung, they greatly increase the surface area for gas exchange between the lungs and bloodstream. Human lungs, for example, contain about 300 million alveoli. They give the lungs a total surface area for gas exchange of up to 90 square meters (968 square feet). That's about as much surface area as one side of a volleyball court! I am facing a new situation today: Two friends read about respiratory systems. Paul read more about the lungs of mammals, while Pete read more about the lungs of frogs. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which student read less about alveoli????
output answer:
Pete
