Problem: Given the question: I read this background article the other day: HIV , or human immunodeficiency virus, causes AIDS. AIDS stands for "acquired immune deficiency syndrome." It is a condition that causes death and does not have a known cure. AIDS usually develops 10 to 15 years after a person is first infected with HIV. The development of AIDS can be delayed with proper medicines. The delay can be well over 20 years with the right medicines. Today, individuals who acquire HIV after 50 years of age can expect to reach an average human life span. I am facing a new situation today: Two college buddies have known each other for 20 years. Tim was HIV positive while John was not and he didn't have a problem with it. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which friend doesn't take medicine to delay AIDS?

The answer is:
John
input question: I read this background article the other day: Sand mining is a direct cause of erosion, and impacts the local wildlife.[2] Various animals depend on sandy beaches for nesting clutches, and mining has led to the near extinction of gharials (a species of crocodile) in India. Disturbance of underwater and coastal sand causes turbidity in the water, which is harmful for organisms like coral that need sunlight. It can also destroy fisheries, financially harming their operators. Removal of physical coastal barriers, such as dunes, sometimes leads to flooding of beachside communities, and the destruction of picturesque beaches causes tourism to dissipate. Sand mining is regulated by law in many places, but is often done illegally.[3] Globally, it is a $70 billion industry, with sand selling at up to $90 per cubic yard.[4] I am facing a new situation today: Two cities located at the sea shore between sand dunes, took 2 different approaches to their economic stability and sources of income for their inhabitants. Dune city was mainly focused on raising animals fishing and tourism, while Gulf city started sand mining operations because of the good prices they received per cubic yard of sand. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which city made less money from sand mining????
output answer: Dune
I read this background article the other day: Increased solar ultraviolet radiation resulting from the Antarctic ozone hole has reduced marine primary productivity (phytoplankton) by as much as 15% and has started damaging the DNA of some fish. Illegal, unreported, and unregulated fishing, especially the landing of an estimated five to six times more Patagonian toothfish than the regulated fishery, likely affects the sustainability of the stock. Long-line fishing for toothfish causes a high incidence of seabird mortality. I am facing a new situation today: Red fishery and Brown fishery were both fishing for Patagonian toothfish. Red fishery was fishing illegally, while Brown fishery was regulated and lawful. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which fishery did more illegal fishing?
----
Answer: Red
Q: I read this background article the other day: It mutates DNA. The Chernobyl disaster was a nuclear accident that occurred on April 26, 1986. It is considered the worst nuclear power plant accident in history. A Russian publication concludes that 985,000 excess cancers occurred between 1986 and 2004 as a result of radioactive contamination. The 2011 report of the European Committee on Radiation Risk calculates a total of 1.4 million excess cancers occurred as a result of this contamination. I am facing a new situation today: In Arizona, there are two cities approximately 300 miles apart. Both of them have nuclear power plants in their town. Blinkton had a catastrophic meltdown at their nuclear power plant approximately 15 years ago. The city, Frafton, has a nearly identical nuclear power plant but has never experienced a nuclear accident before. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which city will have fewer people with cancer?
A: Frafton
Question: I read this background article the other day: Gasoline-powered vehicles emit a lot of harmful materials. Nitrogen oxides are formed when atmospheric nitrogen reacts with oxygen at the high temperatures found in a car engine. Carbon monoxide is a by-product of incomplete combustion of hydrocarbons. Evaporated and unused fuel releases volatile hydrocarbons into the atmosphere to help form smog. The presence of a catalytic converter in the exhaust system of the car causes these materials to react and be changed into less harmful products. I am facing a new situation today: Due to economic sanctions and trade embargoes, Cuban citizens primarily use cars designed in the late 1940s and early 1950s. These cars contain engines that were designed before the introduction of the catalytic converter. Meanwhile trade relations between nearby Panama and Japan have enabled the citizens of Panama to drive cars with the most up to date catalytic converter technology possible. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which country's cars, Cuba's or Panama's, will contribute to less smog formation?
Answer: Panama's
Please answer this: I read this background article the other day: Groundwater salinization compromises buffering properties. Vegetation clearance, along with irrigation, causes serious issues. Irrigation increases the water table and mobilizes salts, and vegetation clearance allows it to come in contact with water habitats and vegetation. This stresses species not adapted to high salinity. High levels of salinity reduces water uptake in plants, by causing stomatal closure, reducing photosynthesis. Forests undergo decline in areas of high salinity and shallow groundwater depths because these conditions make them more susceptible to droughts. Forests undergo decline in areas of high salinity and shallow groundwater depths making them more susceptible to droughts. I am facing a new situation today: In the sixteenth century the State of Michigan had forests all over. But that has long been gone. Especially, in the state's northeast part the vegetation has been cleared in the twentieth century. Wooded areas were replaced by farm lands. All these farmlands were under heavy Irrigation. At one time, in the sixteenth century, plant species like elm and oak used to be plentiful. We still had some elms and oaks in the twentieth century, but they were not great many in number. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Was the mobilized salts in increased or decreased level in northeast Michigan in the twentieth century?
