Which of the following scenarios best explains the Columbian Exchange?

Domesticated animals such as cattle, horses, pigs, and chickens were introduced to the Americas by European colonizers. Prior to this, very few animals had been domesticated in the Americas.

Which of the following best compares a technological consequence of the Green Revolution in more developed and less developed countries?

Farmers in less developed countries were able to increase their profits from growing and exporting high-yield grain to levels similar to those in more developed countries.

Which of the following explains a reason why education and employment rates for women are lower in less developed compared to more developed countries?

Females take primary responsibility for harvesting and cooking food in less developed countries.

More developed countries tend to have greater access to agricultural technology and government-supported loans used to purchase computerized farm equipment. Which of the following best explains the significance of access to these resources?

Government financing and improved technology lead to larger economies of scale and improved efficiency.

Which of the following best explains how a wheat farmer in the Northern Plains region of the United States is able to maximize profits?

Grain farming is an extensive farming practice that can maximize profits in part by lower land costs, lower transportation costs, and imperishability of the product.

A typical grocery store in the United States may sell oranges grown primarily in California during part of the year and oranges grown primarily in South Africa during a different part of the year. Which of the following explains why oranges are available year-round in the United States?

Grocery stores sell oranges that are grown in locations with similar climates but different growing seasons.

Which of the following best explains the significance of a similarity among locations where olives, figs, grapes and lemons are grown?

Intensive agriculture is practiced in a Mediterranean climate.

Which of the following best explains how irrigated commercial agriculture in arid environments creates both environmental opportunities and challenges?

Irrigation increases production but potentially depletes water resources.

Which of the following best explains the spatial patterns illustrated in von Thünen's model?

Labor-intensive farming of vegetables is done in small-scale plots in market gardens, while extensive grain crops are grown in large-scale fields far from the market town.

Which of the following best explains the farming practice related to plantation agriculture?

Plantation farming is considered to be an intensive farming practice because it requires large inputs of labor and capital to produce the crop.

The Green Revolution led to an increase in food production in many places around the world, but there have been some negative consequences. Which of the following explains one of the negative consequences of the Green Revolution that would be of greater concern for people in developing countries than for people in more-developed countries?

Runoff of agricultural chemicals into the local groundwater that pollutes water resources

Agriculture is practiced at the local scale, and agricultural yields are measured at the national scale. Which of the following best explains why the concept of the global system of agriculture is helpful to geographers?

The concept helps geographers simplify and visualize a vast and complicated global supply chain.

Commercial agriculture in dry climates relies heavily on irrigation. Which of the following best explains an environmental concern that results from irrigation in arid regions?

The soil will have increased salinity, leading to soil erosion and reduced nutrients in the soil for plant health.

In 2017, the United States exported approximately $500 million of beef to Mexico, and Mexico exported approximately $500 million of beef to the United States. Which of the following best explains this international supply chain?

United States and Mexican producers rely on each other's market to sell certain beef products.

Which of the following correctly explains the relationship between wheat and its early hearth of domestication?

Wheat was first domesticated in Mesopotamia because of a favorable climate and a great diversity of wild grains that led to crossbreeding of seeds.

Which of the following best explains patterns of subsistence and commercial agriculture in West African countries such as Ghana and Côte d'Ivoire?

While some farmers are engaged in subsistence agriculture practices, there is significant commercial farming focused on luxury goods for export, such as coffee and cocoa.

Which of the following best explains the differences between countries with higher and lower percentages of women working in agriculture?

Countries with large percentages of female employment in agriculture tend to be mostly rural and are reliant on subsistence agriculture.

Which of the following explains an economic benefit of cattle production using feedlots rather than grass pastures?

Agricultural technology has increased the economy of scale and the carrying capacity of feedlots, increasing profits for the farmer.

Slash-and-burn cultivation is an agricultural practice used by subsistence farmers in tropical forest areas. Which of the following best explains an environmental effect of this practice?

Air pollution and long-term land-cover change are side effects of slash-and-burn agriculture that have a long-ranging effect on a broader region.

Which of the following explains the prevalence of banana plantations in Central America?

Banana plants were brought to Central America from Southeast Asia to be grown closer to markets in the United States and Canada.

Which of the following best explains a negative economic consequence of the Green Revolution in less developed countries as compared to more developed countries?

Because of the increased capital investment required to produce new crop varieties using technology that was pioneered in more developed countries, there was an increase in wealth disparity in many farming communities in less developed countries.

Which of the following best explains why in the model the amount of land used for dairying is much smaller than the pasture used for beef cattle?

Dairy cows must be kept close to farmhouses, as they require daily milking, and milk must be produced close to consumers, as it is highly perishable.

Since the mid-twentieth century, wheat production has risen dramatically in some regions of the world but not others, which may increase the uneven development among countries. Which statement best explains the increase in wheat production in Europe and the United States compared to sub-Saharan Africa?

Farmers in Europe and the United States use high-yield seeds and other technology but farmers in sub-Saharan Africa depend on low levels of mechanization and non-genetically modified seeds.
