Question 1 of 16
All Questions (16)
A) Free-range pastures
B) Feedlots
C) Organic farms
D) Grazing lands
Correct Answer: B
The content explicitly states that Concentrated Animal Feeding Operations (CAFOs) are also called feedlots.
A) The requirement for large areas of land for grazing.
B) The contamination of ground and surface water from organic waste.
C) The degradation of arid regions into deserts.
D) The loss of vegetation leading to soil erosion.
Correct Answer: B
The text states that CAFOs generate large amounts of organic waste which can contaminate ground and surface water. The other options are associated with free-range grazing and overgrazing.
A) It generates large amounts of concentrated waste.
B) The meat is typically less healthy due to antibiotic use.
C) It is more expensive for consumers and requires large land areas.
D) It readies livestock for slaughter more quickly.
Correct Answer: C
The content identifies two main drawbacks for free-range grazing: it requires large land areas and is more expensive for consumers. The other options describe CAFOs or are incorrect.
A) CAFOs are crowded and animals are fed grains.
B) Free-range grazing requires large land areas.
C) It takes approximately 20 times more land to produce the same amount of calories from meat as from plants.
D) Overgrazing can lead to soil erosion and desertification.
Correct Answer: C
The text directly quantifies the inefficiency of meat production by stating it takes 'approximately 20 times more land to produce the same amount of calories from meat as from plants.'
A) Soil erosion
B) Water contamination
C) Desertification
D) Deforestation
Correct Answer: C
The content defines desertification as 'the degradation of low precipitation regions toward being increasingly arid,' and links it to overgrazing.
A) It is less expensive for consumers.
B) It quickly readies livestock for slaughter.
C) Organic waste acts as a natural fertilizer.
D) It requires a small amount of land.
Correct Answer: C
The text explicitly states that in free-range grazing, 'organic waste acts as fertilizer.' The other options are either benefits of CAFOs or drawbacks of free-range grazing.
A) Increased use of antibiotics in livestock.
B) Contamination of surface water by organic waste.
C) Loss of vegetation and subsequent soil erosion.
D) Lower prices for meat products for consumers.
Correct Answer: C
The text states that overgrazing 'causes loss of vegetation, leading to soil erosion.' The other options are related to CAFOs.
A) Conservation of water
B) Reduction in methane and N2O emissions
C) Lower cost of meat for consumers
D) Improvement of topsoil
Correct Answer: C
The text lists reduced emissions, water conservation, reduced antibiotic use, and improved topsoil as benefits of less meat consumption. It does not suggest that reduced consumption would lower the cost of meat; in fact, less-intensive methods like free-range are more expensive.
A) Grass
B) Organic waste
C) Grains
D) Antibiotic-free feed
Correct Answer: C
The provided content specifies that in CAFOs, 'animals are fed grains.'
A) CAFOs produce healthier meat, while free-range grazing is better for the environment.
B) CAFOs are economically efficient but pose significant waste management challenges, whereas free-range is less polluting but more land-intensive and expensive.
C) Both methods have a similar impact on land use, but CAFOs are more expensive for the consumer.
D) Free-range grazing leads to desertification, while CAFOs improve topsoil quality.
Correct Answer: B
This option correctly summarizes the key points: CAFOs are less expensive (economically efficient) but create waste contamination issues. Free-range grazing is more expensive and requires more land, but waste is managed naturally as fertilizer.
A) Free-range grazing
B) Concentrated Animal Feeding Operations (CAFOs)
C) A method that prevents soil erosion
D) A method that uses organic waste as fertilizer
Correct Answer: B
The text explicitly states that meat from CAFOs is 'less expensive for consumers,' while meat from free-range grazing is 'more expensive for consumers.'
A) The implementation of CAFOs to reduce land use.
B) The feeding of grains to livestock in feedlots.
C) Overgrazing by too many animals in the region.
D) The use of animal waste as a natural fertilizer.
Correct Answer: C
The text directly links overgrazing to the loss of vegetation, which leads to soil erosion and can cause desertification (the expansion of arid conditions). The other options are not associated with these specific environmental impacts.
A) Animals are crowded together in small spaces.
B) The resulting meat is less expensive for consumers.
C) Animals are allowed to graze on grass.
D) Large amounts of waste are generated in a concentrated area.
Correct Answer: C
The text specifies that free-range grazing 'allows animals to graze on grass,' while CAFOs use grain feed. The other options are all characteristics of CAFOs.
A) Ozone and sulfur dioxide
B) Carbon monoxide and volatile organic compounds
C) CO2, methane, and N2O
D) Chlorofluorocarbons (CFCs)
Correct Answer: C
The text specifically states that less meat consumption could reduce 'CO2, methane, and N2O emissions.'
A) Free-range grazing
B) Overgrazing
C) Desertification
D) Concentrated Animal Feeding Operations (CAFOs)
Correct Answer: D
This question synthesizes the key descriptors of CAFOs provided in the text: they are crowded, animals are fed grains, they are quickly readied for slaughter, and their waste can contaminate water.
A) It contains more calories per serving.
B) It is typically free from antibiotics.
C) It is less expensive to purchase.
D) The animals are fed a high-calorie grain diet.
Correct Answer: B
The text explicitly mentions that meat from free-range grazing is 'typically free from antibiotics,' which is a factor many consumers consider when making health-conscious choices.
