Problem: Background: 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]  Paragraph: 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.  Given the paragraph above, please answer correctly the following question: Which group had more inebriated people experiencing heat illness?

A: Group One


Problem: Background: Tropical forests (rainforests) receive more insolation and rainfall over longer growing seasons than any other environment on earth. With these elevated temperatures, insolation and rainfall, biomass is extremely productive leading to the production of as much as 800 grams of carbon per square meter per year. Higher temperatures and larger amounts of water contribute to higher rates of chemical weathering. Increased rates of decomposition cause smaller amounts of fulvic acid to percolate and leach metals from the zone of active weathering. Thus, in stark contrast to soil in forests, tropical forests have little to no podzolization and therefore do not have marked visual and chemical contrasts with the soil layers. Instead, the mobile metals Mg, Fe and Al are precipitated as oxide minerals giving the soil a rusty red color.  Paragraph: David is an environmental scientist. Last summer he visited the tropical forest in Brazil. He labeled that part of his study as forest A. To understand the differences between forests he then visited the temperate forest in Germany. He labeled that part of his study as forest B. He found significant differences in these two types of forests.  Given the paragraph above, please answer correctly the following question: Would forest A get less or more insolation than forest B?

A: more


Problem: Background: Carbon dioxide is the most significant long-lived greenhouse gas in Earth's atmosphere. Since the Industrial Revolution anthropogenic emissions – primarily from use of fossil fuels and deforestation – have rapidly increased its concentration in the atmosphere, leading to global warming.  Carbon dioxide also causes ocean acidification because it dissolves in water to form carbonic acid.  Paragraph: Ted and Larry studied environmental sciences. They are learning about greenhouse gasses this week. Ted reads about carbon dioxide, while Larry reads about methane gas.  Given the paragraph above, please answer correctly the following question: Which student read less about anthropogenic emissions?

A: Larry


Problem: Background: Compared to conventional milk production, organic milk production tends to have lower eutrophication potential per ton of milk or per hectare of farmland, because it potentially reduces leaching of nitrates (NO3−) and phosphates (PO4−) due to lower fertilizer application rates. Because organic milk production reduces pesticides utilization, it increases land use per ton of milk due to decreased crop yields per hectare. Mainly due to the lower level of concentrates given to cows in organic herds, organic dairy farms generally produce less milk per cow than conventional dairy farms. Because of the increased use of roughage and the, on-average, lower milk production level per cow, some research has connected organic milk production with increases in the emission of methane.Animal welfare issues vary among dairy farms and are not necessarily related to the way of producing milk (organically or conventionally).  Paragraph: Two neighboring dairy farms produced milk for half the state.  Berry farm produced conventional milk, while Rose farm produced organic milk.  Given the paragraph above, please answer correctly the following question: Which farm had milk production which reduced leaching of nitrates?

A:
Rose
