Question: 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 identical twin brothers go to the doctor to get blood work done and also checked for STDs as part of their routine medical checkups. Neither man thinks they have caught anything, but both are sexually active so they want to get checked out. After getting the test results, the doctor tells Hank that he has strep throat, but no STDs. Jacob is told that he has hepatitis B. The doctor gives both men information about what medication to take and what they need to do to manage their diseases. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which man's skin is less likely to turn yellow?
Answer: Hank
[Q]: 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: The government of Ecuador has been actively pushing to increase biodiversity. They have been quite successful in their pursuit. Moreover, the citizens of Ecuador are receptive about the idea of increased biodiversity. On the contrary, the Government of Oman was not very active in increasing the biodiversity of their country. As a result, Oman, at present, is not very biodiverse. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which place would have more key species, Ecuador or Oman?
****
[A]: Ecuador
input: Please answer the following: I read this background article the other day: Making these healthy lifestyle choices can also help prevent some types of cancer. In addition, you can lower the risk of cancer by avoiding carcinogens , which are substances that cause cancer. For example, you can reduce your risk of lung cancer by not smoking. You can reduce your risk of skin cancer by using sunscreen. How to choose a sunscreen that offers the most protection is explained below ( Figure below ). Some people think that tanning beds are a safe way to get a tan. This is a myth. Tanning beds expose the skin to UV radiation. Any exposure to UV radiation increases the risk of skin cancer. It doesn't matter whether the radiation comes from tanning lamps or the sun. I am facing a new situation today: Keith is a doctor at the city hospital. Today, he is seeing six patients, patient A, patient B, patient C, patient D, patient E, and patient F. Patient A is a smoker, but patient B is not a smoker. Patient C uses sunscreen, but patient D does not use any sunscreen. Patient E tans with tanning lamps, but patient F tans in the sun. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which patient would be more susceptible to skin cancer, patient E or patient C?
++++++++++
output: patient E
Please answer this: I read this background article the other day: When waves travel into areas of shallow water, they begin to be affected by the ocean bottom. The free orbital motion of the water is disrupted, and water particles in orbital motion no longer return to their original position. As the water becomes shallower, the swell becomes higher and steeper, ultimately assuming the familiar sharp-crested wave shape. After the wave breaks, it becomes a wave of translation and erosion of the ocean bottom intensifies. I am facing a new situation today: Most surfers used Wide beach because of the areas of shallow water, but some surfers were happy with Sandy beach, although the water was much deeper at the shore there. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which beach experiences a higher and steeper swell?
++++++++
Answer: Wide
Problem: I read this background article the other day: In practice, the diameter of the aperture is chosen based on the focal length of the lens, the diameter and quality of the input beam, and its wavelength (longer wavelengths require larger apertures). If the hole is too small, the beam quality is greatly improved but the power is greatly reduced. If the hole is too large, the beam quality may not be improved as much as desired. The size of aperture that can be used also depends on the size and quality of the optics. To use a very small pinhole, one must use a focusing lens with a low f-number, and ideally the lens should not add significant aberrations to the beam. The design of such a lens becomes increasingly more difficult as the f-number decreases. I am facing a new situation today: David needs to purchase a camera for his photography class. He went to the local consumer electronics store to find himself a good camera. Two cameras caught his eye, camera A and camera B. Camera A had a very small pinhole, but camera B had larger aperture. David needs to decide which camera should he buy. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which camera would have higher beam power, camera A or camera B?

A: camera B
input: Please answer the following: I read this background article the other day: If a nuclear chain reaction is uncontrolled, it produces a lot of energy all at once. This is what happens in an atomic bomb. If a nuclear chain reaction is controlled, it produces energy more slowly. This is what occurs in a nuclear power plant. The reaction may be controlled by inserting rods of material that do not undergo fission into the core of fissioning material (see Figure below ). The radiation from the controlled fission is used to heat water and turn it to steam. The steam is under pressure and causes a turbine to spin. The spinning turbine runs a generator, which produces electricity. I am facing a new situation today: A war has started. In this war, no side shows a clear side of winning and the casualties are already high. In a desperate attempt to end the war quickly country A decides it wants to try to drop an atomic bomb on country B. They succeed. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Will the bomb detonation cause a lot of energy all at once or slowly over time?
++++++++++
output:
all at once
