Problem: Given the question: I read this background article the other day: Biodiversity is determined by many things, and one of them is abiotic stress. If an environment is highly stressful, biodiversity tends to be low. If abiotic stress does not have a strong presence in an area, the biodiversity will be much higher.This idea leads into the understanding of how abiotic stress and endangered species are related. It has been observed through a variety of environments that as the level of abiotic stress increases, the number of species decreases. This means that species are more likely to become population threatened, endangered, and even extinct, when and where abiotic stress is especially harsh.  I am facing a new situation today: Two neighboring regions were exposed to different levels of abiotic stress. Eastern region was exposed to high levels of abiotic stress, while Western region was almost stress-free.  Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which region had more species go extinct?
++++++++++++++++++++++++++++++++
The answer is:
Eastern

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 groups of students studied Biology. Group One studied mammals, while Group Two studied birds. They focused on the respiratory system.  Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which group of students learned less about the lungs of mammals????
output answer: Two

I read this background article the other day: 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/ .  I am facing a new situation today: Dean and Paul both went to volunteered in Africa. They had a blood test when they came back. Paul had been infected with the HIV virus while Dean was healthy and clean.  Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which friend does not have a virus that causes Acquired Immunodeficiency Syndrome?
----
Answer: Dean

Q: I read this background article the other day: 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.  I am facing a new situation today: Greg is a doctor with the city hospital. Today, he is seeing two patients, patient A and patient B. Patient A maintains a high-fat diet, but patient B does not maintain a high fat diet. Greg is advising the patients how lifestyle change can improve their health.  Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which patient would have less lipid in the blood, patient A or patient B?
A: patient B

Question: I read this background article the other day: The Laffer curve depicts the amount of government revenue as a function of the rate of taxation. It shows that for a tax rate above a certain critical rate, government revenue starts decreasing as the tax rate rises, as a consequence of a decline in labour supply. This theory supports that, if the tax rate is above that critical point, a decrease in the tax rate should imply a rise in labour supply that in turn would lead to an increase in government revenue.  I am facing a new situation today: After the second world war Germany and France took two different policies in respect to taxation. After the war Germany, then West Germany, has mostly elected pro-capitalist governments. As a consequence, Germany implemented tax rate below the critical rate. But France took the other way. Their mostly pro-socialist governments implemented tax rate above the critical rate. As a result, businesses had to make informed decisions while doing business in these countries.  Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Would Germany's government revenue increase or decrease as a result of their tax policy?
Answer: increase

Please answer this: I read this background article the other day: "There is now unequivocal evidence that biodiversity loss reduces the efficiency by which ecological communities capture biologically essential resources, produce biomass, decompose and recycle biologically essential nutrients... There is mounting evidence that biodiversity increases the stability of ecosystem functions through time... Diverse communities are more productive because they contain key species that have a large influence on productivity and differences in functional traits among organisms increase total resource capture... The impacts of diversity loss on ecological processes might be sufficiently large to rival the impacts of many other global drivers of environmental change... Maintaining multiple ecosystem processes at multiple places and times requires higher levels of biodiversity than does a single process at a single place and time."  I am facing a new situation today: Nicaragua is one of the most biodiverse countries in the Americas. They boast over five hundred species of birds, and thousands of species of plants. Across the pond in England the situation is completely different. Centuries of extensive farming, industrialization, and urban sprawls have made it one of the least biodiverse place on Earth.  Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Would the ecosystem functions be less or more stable in Nicaragua than in England?
