Question 1

Which of the following best describes a major consequence of the Green Revolution on global agriculture?

Accepted Answer

It increased food production through new technologies and crop varieties, but also greatly increased energy and chemical inputs.

Question 2

According to the Laws of Thermodynamics and the diagram showing feed input versus edible output, which dietary change would most efficiently support a larger human population?

Accepted Answer

Feeding lower on the food chain, such as consuming more grains and vegetables.

Question 3

Which of the following is NOT a direct environmental consequence of large-scale feedlot operations?

Accepted Answer

Decreased pollution from animal waste.

Question 4

What is a major risk associated with the use of biological control agents for pest management?

Accepted Answer

They may become invasive species themselves, disrupting local ecosystems.

Question 5

Which of the following statements about GMOs is supported by the study materials?

Accepted Answer

GMOs have led to increased yields and decreased pesticide use in some cases.

Question 6

A farmer wants to reduce pesticide use while maintaining crop yields. Which strategy best aligns with integrated pest management (IPM)?

Accepted Answer

Using a combination of crop rotation, biological control, and close monitoring of pest populations.

Question 7

Which of the following is a potential ecological drawback of widespread GMO crop cultivation?

Accepted Answer

Transfer of transgenic genes to wild relatives, potentially contaminating local plant genomes.

Question 8

Based on the pie charts of GM crops by type and by nation, which crop and country combination represents the largest share of global GM crop production?

Accepted Answer

Soybeans in the United States.

Question 9

Why is crop diversity important for sustainable agriculture?

Accepted Answer

It preserves genetic resources that may be crucial for future food security and adaptation.

Question 10

Which of the following best explains why organic agriculture is unlikely to feed the entire world population at present?

Accepted Answer

Yields from organic agriculture are generally lower than those from conventional agriculture.

Question 11

A farmer is considering switching from beef to chicken production. Based on the diagrams provided, which of the following is a likely environmental benefit?

Accepted Answer

Chicken production results in lower greenhouse gas emissions per kilogram of protein compared to beef.

Question 12

Which of the following is a key requirement for agriculture to be considered sustainable?

Accepted Answer

It must conserve resources for future generations while providing food security and profitability.

Question 13

Which of the following best describes the process of creating a transgenic GMO crop, as shown in the diagram?

Accepted Answer

Inserting a gene of interest from one organism into the DNA of another organism using recombinant DNA technology.

Question 14

If a region experiences a rapid increase in herbicide-resistant weeds, what is the most likely cause based on the provided materials?

Accepted Answer

Overuse of a single type of herbicide, especially with herbicide-tolerant GM crops.

Question 15

Which of the following is a benefit of aquaculture compared to traditional wild-capture fisheries?

Accepted Answer

It reduces harvest pressure on wild fish populations and provides a reliable protein source.

Question 16

A country wants to reduce the environmental impact of its food system. According to the materials, which action would have the greatest effect?

Accepted Answer

Reducing national meat consumption.

Question 17

Which of the following is a plausible reason why farmers in developing countries may not benefit as much from GM crops?

Accepted Answer

Most GM crops are patented, preventing farmers from saving seeds for the next season.

Question 18

Which of the following best describes the trend in grain production per person from 1960 to 2010, as shown in the graph?

Accepted Answer

Grain production per person increased initially but then leveled off or declined slightly in recent decades.
