[Q]: I read this background article the other day: There is worldwide concern about the relationship between climate change and the use of fossil fuels. Many scientists believe that increased use of these fuels (in vehicles and other gas-powered equipment) has the potential to irreversibly damage our environment. In addition to the environmental concerns, supplies of fossil fuels are finite, and because they are non-renewable energy sources, we will eventually need alternatives. New developments in batteries and other energy storage devices are being explored to help deal with these issues. Electrochemical processes are at the heart of these new technologies. I am facing a new situation today: Two countries used different fuels as power sources for their activities. Alsacia used fossil fuels, while Lorena devised more advanced energy storage devices, therefore relying on electricity. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which country contributed less to the irreversible damage our environment?
****
[A]: Lorena
input: Please answer the following: I read this background article the other day: Hepatitis B is a disease of the liver. It is caused by a virus called hepatitis B, which can be passed through sexual activity. Hepatitis B causes vomiting. It also causes yellowing of the skin and eyes. The disease goes away on its own in some people. Other people are sick for the rest of their lives. In these people, the virus usually damages the liver. It may also lead to liver cancer. Medicines can help prevent liver damage in these people. There is also a vaccine to protect against hepatitis B. I am facing a new situation today: Two friends ate lots of deviled eggs for Easter this year. Danny felt sick and went to the doctor where he found out he had been infected with hepatitis B. Paul was ok and didn't require medical attention. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which friend experienced more yellowing of the skin?
++++++++++
output: Danny
Please answer this: I read this background article the other day: White blood cells also make chemicals that cause a fever. A fever is a higher-than-normal body temperature. Normal human body temperature is 98.6F (37C). Most bacteria and viruses that infect people reproduce fastest at this temperature. When the temperature is higher, the pathogens cannot reproduce as fast, so the body raises the temperature to kill them. A fever also causes the immune system to make more white blood cells. In these ways, a fever helps the body fight infection. I am facing a new situation today: Stephanie is a nurse at the local high school. Recently, the flu has been going around and she has had many students come into her office feeling ill. When a student comes in, the first thing she does is check their temperature to test for a fever. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: If a student has a fever are they healthy or do they have a virus or infection?
++++++++
Answer: they have a virus or infection
Problem: I read this background article the other day: Candied fruit, also known as crystallized fruit or glace fruit, has existed since the 14th century. Whole fruit, smaller pieces of fruit, or pieces of peel, are placed in heated sugar syrup, which absorbs the moisture from within the fruit and eventually preserves it. Depending on size and type of fruit, this process of preservation can take from several days to several months.[1] This process allows the fruit to retain its quality for a year.[2] The continual process of drenching the fruit in syrup causes the fruit to become saturated with sugar, preventing the growth of spoilage microorganisms due to the unfavourable osmotic pressure this creates.[3] I am facing a new situation today: Mary and Ann got some fruit as a gift from a friend. Mary decided to candy the fruit, while Ann decided to eat them fresh, Mary received plums, peaches, apples and oranges. Ann got pears, quince, cherries and blackberries. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which fruit retained their quality longer peaches or cherries?

A: peaches
Problem: I read this background article the other day: The trade-off theory of capital structure is the idea that a company chooses how much debt finance and how much equity finance to use by balancing the costs and benefits. The classical version of the hypothesis goes back to Kraus and Litzenberger[1] who considered a balance between the dead-weight costs of bankruptcy and the tax saving benefits of debt. Often agency costs are also included in the balance. This theory is often set up as a competitor theory to the pecking order theory of capital structure. A review of the literature is provided by Frank and Goyal.[2] An important purpose of the theory is to explain the fact that corporations usually are financed partly with debt and partly with equity. It states that there is an advantage to financing with debt, the tax benefits of debt and there is a cost of financing with debt, the costs of financial distress including bankruptcy costs of debt and non-bankruptcy costs (e.g. staff leaving, suppliers demanding disadvantageous payment terms, bondholder/stockholder infighting, etc.). The marginal benefit of further increases in debt declines as debt increases, while the marginal cost increases, so that a firm that is optimizing its overall value will focus on this trade-off when choosing how much debt and equity to use for financing. I am facing a new situation today: Company X stopped taking on more debt, and decided to file for bankruptcy, while company Y, kept benefiting from the tax benefits of debt, having a lower debt level. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which company had less problems with stockholders fighting, company X or company Y?

A:
company Y
