I read this background article the other day: Among the tropical oceans, the western Indian Ocean hosts one of the largest concentration of phytoplankton blooms in summer, due to the strong monsoon winds. The monsoonal wind forcing leads to a strong coastal and open ocean upwelling, which introduces nutrients into the upper zones where sufficient light is available for photosynthesis and phytoplankton production. These phytoplankton blooms support the marine ecosystem, as the base of the marine food web, and eventually the larger fish species. The Indian Ocean accounts for the second largest share of the most economically valuable tuna catch. Its fish are of great and growing importance to the bordering countries for domestic consumption and export. Fishing fleets from Russia, Japan, South Korea, and Taiwan also exploit the Indian Ocean, mainly for shrimp and tuna.Research indicates that increasing ocean temperatures are taking a toll on the marine ecosystem. A study on the phytoplankton changes in the Indian Ocean indicates a decline of up to 20% in the marine phytoplankton in the Indian Ocean, during the past six decades. The tuna catch rates have also declined abruptly during the past half century, mostly due to increased industrial fisheries, with the ocean warming adding further stress to the fish species.Endangered marine species include the dugong, seals, turtles, and whales.An Indian Ocean garbage patch was discovered in 2010 covering at least 5 million square kilometres (1.9 million square miles). Riding the southern Indian Ocean Gyre, this vortex of plastic garbage constantly circulates the ocean from Australia to Africa, down the Mozambique Channel, and back to Australia in a period of six years, except for debris that get indefinitely stuck in the centre of the gyre.The garbage patch in the Indian Ocean will, according to a 2012 study, decrease in size after several decades to vanish completely over centuries.  Over several millennia, however, the global system of garbage patches will accumulate in the North Pacific.In 2016 six new animal...  I am facing a new situation today: Two of Earth's oceans provide vast quantities of fish for human consumption. The Indian ocean hosts a large concentration of phytoplankton blooms in summer. The Pacific ocean has less phytoplankton and nutrients for marine life.  Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which ocean experiences a weaker coastal upwelling?
----
Answer: Pacific

Q: I read this background article the other day: Many different chemical substances cause cancer. Dozens of chemicals in tobacco smoke, including nicotine, have been shown to cause cancer ( Figure below ). In fact, tobacco smoke is one of the main sources of chemical carcinogens. Smoking tobacco increases the risk of cancer of the lung, mouth, throat, and bladder. Using smokeless tobacco can also cause cancer. Other chemicals that cause cancer include asbestos, formaldehyde, benzene, cadmium, and nickel.  I am facing a new situation today: Two friends met after 20 years. Tom had been smoking tobacco all these years and had some health problems related to that, while Randy quit smoking 25 years ago.  Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which friend was at a lower risk for developing cancer?
A: Randy

Question: I read this background article the other day: 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.  I am facing a new situation today: 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.  Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which brother was more at risk for heart disease?
Answer: Liam

[Q]: I read this background article the other day: New species develop naturally through the process of natural selection . Due to natural selection, organisms with traits that better enable them to adapt to their environment will tend to survive and reproduce in greater numbers. Natural selection causes beneficial heritable traits to become more common in a population and unfavorable heritable traits to become less common. For example, a giraffe’s neck is beneficial because it allows the giraffe to reach leaves high in trees. Natural selection caused this beneficial trait to become more common than short necks.  I am facing a new situation today: Scientists studied two groups of mammals. Group One developed natural selection after a few decades, while group Two didn't. It was yet to be determined why that happened.  Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which group will develop less naturally because of the lack of natural selection?
****
[A]: group Two

input: Please answer the following: I read this background article the other day: Storing large volumes of data – When storing XML to either file or database, the volume of data a system produces can often exceed reasonable limits, with a number of detriments: the access times go up as more data is read, CPU load goes up as XML data takes more power to process, and storage costs go up. By storing XML data in Fast Infoset format, data volume may be reduced by as much as 80 percent.  I am facing a new situation today: Bob works for a data storage company. He has now three projects, project A, project B, and project C, simultaneously going on. All of them involves storing  XML data. Project A has small volume of data, but project B and project C has large volume of data. He applied Fast Infoset format for project B, but didn't apply that format for project C.  Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which project would have higher access times, project A or project C?
++++++++++
output: project C

I read this background article the other day: Thermoclines, or sudden changes in temperature. Where the air temperature is higher than the water temperature, shallow water may be warmed by the air and the sunlight but deeper water remains cold resulting in a lowering of temperature as the diver descends. This temperature change may be concentrated over a small vertical interval, when it is called a thermocline.[3][4] Where cold, fresh water enters a warmer sea the fresh water may float over the denser saline water, so the temperature rises as the diver descends.[3] In lakes exposed to geothermal activity, the temperature of the deeper water may be warmer than the surface water. This will usually lead to convection currents.[3]  I am facing a new situation today: The underwater fishing teams picked their spots early. Team Bob went at the mouth of the river, where the freshwater met the salty seawater in the hope that more turbidity from the river and more nutrients will attract more fish. Team Dan went south where they knew there was less of a thermocline, so they could catch fish without taking risks.  Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which team had their crew members to fewer risks than necessary?
----
Answer:
Dan
