Question: input question: I read this background article the other day: Unfortunately, the layer of good ozone is being destroyed by air pollution. The chief culprits are chlorine and bromine gases. They are released in aerosol sprays, coolants, and other products. Loss of ozone has created an ozone hole over Antarctica. Ozone depletion results in higher levels of UV radiation reaching Earth. In humans, this increases skin cancers and eye cataracts. It also disturbs the nitrogen cycle, kills plankton, and disrupts ocean food webs. The total loss of the ozone layer would be devastating to most life. It’s rate of loss has slowed with restrictions on pollutants, but it is still at risk.  I am facing a new situation today: Bend city used a lot of fossil fuels to generate electricity. Hop city, another city from the same county, used only alternative sources of energy.  Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which city caused more acid rain????
output answer: Bend

input question: I read this background article the other day: The earliest members of the human species evolved around 200,000 years ago in Africa. Early humans lived in small populations of nomadic hunters and gatherers. Human beings remained in Africa until about 40,000 years ago. After that, they spread throughout Europe, Asia, and Australia. By 10,000 years ago, the first human beings colonized the Americas. During this long period of time, the total number of human beings increased very slowly. Birth rates were fairly high but so were death rates, producing low rates of population growth.  I am facing a new situation today: Archaeologists studied data about human settlements. One was 100,000 years old called village R, and the other one was about 9,000 years old called village N. The older settlement was located in Africa, the other one wasn't.  Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which village had people that lived in smaller populations????
output answer: village R

input 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: Hill town was full of gasoline powered vehicles, while Valley town 50 miles away, banned all gas powered vehicles and allows only electrical vehicles or horse-and-buggies.  Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which town had more volatile hydrocarbons in the atmosphere????
output answer: Hill

input question: I read this background article the other day: Common causes of heat exhaustion include:[1]  Hot, sunny, humid weather Physical exertion, especially in hot, humid weather Due to impaired thermoregulation, elderly people and infants can get serious heat illness even at rest, if the weather outside is hot and humid, and they are not getting enough cool air. Some drugs, such as diuretics, antihistamines, beta-blockers, alcohol, ecstasy, and amphetamines can cause an increase in the risk of heat exhaustion.[2] Especially during physical exertion, risk factors for heat exhaustion include:[1]  Wearing dark, padded, or insulated clothing; hats; and/or helmets (for example, football pads or turnout gear) Having a higher percentage of body fat Dehydration Fever Some medications, like beta blockers and antipsychotic medicines[2]  I am facing a new situation today: Two groups of people were out in the sunny, humid weather of Illinois. Group One wore black clothes and helmets, and Group Two wore white, light clothing. Both groups were comprised of people of all ages and fitness levels and exercised in the sun for an hour.  Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which group had fewer inebriated people experiencing heat illness????
output answer:
Answer: Group Two
