[Q]: Background: Ski cross is a type of skiing competition. Despite its being a timed racing event, it is often considered part of freestyle skiing because it incorporates terrain features traditionally found in freestyle. Ski cross courses have both naturally occurring terrain and artificial features including big-air jumps and high-banked turns. What sets ski cross apart from other alpine skiing disciplines is that there's more than one skier racing down the course.[1] Any intentional contact with other competitors leads to disqualification. Paragraph: Greg is an avid skier. He competes in many skiing competitions. He won several medals in those competitions. This November he will compete in two competitions - competition A, which is ski cross and competition B, which is an alpine skiing competition. Greg's fellow skier Bob is also competing in the same competitions. They both are exited about it. Given the paragraph above, please answer correctly the following question: In which competition they will see multiple skiers racing down the course, competition A or competition B?
****
[A]: competition A

[Q]: 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: Jimmy is currently shopping at his local grocery store during his weekly trip to get food and other necessities. He first picks up some frozen pizzas, his favorite meal when he is feeling lazy after work, and then stops off to pick up a loaf of bread. He then walks over to the dairy section to pick up some cheese for his lunches. Jimmy never buys milk, but today he has a sudden urge to get some. He walks over to the milk refrigerators and looks at all the options. He is currently debating between two brands, Luchene and Jean's. While trying to decide, he notices a sticker on the Luchene gallon that says "organic," but is unable to find any such indication on the gallon of Jean's milk. After asking an employee, it is confirmed that Jean's is not organic milk. Unable to make up his mind, Jimmy simply leaves without buying any milk. Given the paragraph above, please answer correctly the following question: Which brand requires less cows to produce the same amount of milk?
****
[A]: Jean's

[Q]: Background: The Keystone XL Pipeline would transport oil from the oil sands in Alberta, Canada. The oil would travel into the United States. In the U.S. it would be refined. The pipeline is controversial. A leak could cause damage to wildlife habitat. A leak could also release enough oil to contaminate the Ogallala Aquifer. The Aquifer is crucial to agriculture and urban development in the Midwestern U.S. When burned, the fuel from the oil sands would increase pollutants. Greenhouse gases into the atmosphere would increase. The future of the pipeline is currently on hold. Paragraph: Lawmakers were debating the pros and cons of Keystone XL Pipeline. One group of lawmakers proposed that the pipeline be constructed. They put their proposal in proposal A. The rival group of lawmakers proposed that the pipeline should not be build. They put their proposal in proposal B. Lawmakers would now have to choose one of the proposals. Given the paragraph above, please answer correctly the following question: Would proposal B hurt or benefit the wildlife habitat?
****
[A]: benefit

[Q]: Background: You generally can't see, smell, taste, hear, or feel radiation. Fortunately, there are devices such as Geiger counters that can detect radiation. A Geiger counter, like the one pictured in the Figure below , contains atoms of a gas that is ionized if it encounters radiation. When this happens, the gas atoms change to ions that can carry an electric current. The current causes the Geiger counter to click. The faster the clicks occur, the higher the level of radiation. You can see a video about the Geiger counter and how it was invented at the URL below. Paragraph: Keith landed a job with the EPA. As part of his training he needed to learn how the Geiger counter works. To learn more about the counter he tested it in three different locations, location A, location B, and location C. Location A had very high radiation; location B had low radiation; and location C didn't have any radiation. Keith learned how the counter works in locations with varying degrees of radiation. Given the paragraph above, please answer correctly the following question: In which location the counter would have electirc current, location B or location C?
****
[A]:
location B
