The origin of agriculture is located in Asia, specifically in the Fertile Crescent region of the Near East. This area, which includes parts of modern-day Iraq, Syria, and Turkey, is where some of the earliest evidence of crop cultivation and animal domestication has been found. This development marks the beginning of the Neolithic Revolution, which transformed human societies from hunter-gatherers to settled agriculturalists.
2.
What does "cultivate" mean?
Correct Answer
A. To grow
Explanation
The term "cultivate" in agriculture refers to the process of preparing land, planting seeds, and nurturing plants to encourage healthy growth. Cultivation includes tasks such as tilling soil, adding nutrients, managing water, and removing weeds, all aimed at creating the best conditions for crops to flourish. While "cultivate" primarily means to grow plants, it also encompasses the care and attention needed to produce healthy, abundant crops.
3.
How were humans surviving before the agricultural revolution? (Check all that apply)
Correct Answer(s)
B. Hunting animals
E. Gathering crops
Explanation
Before the agricultural revolution, humans primarily survived through hunting animals for food and gathering wild plants, fruits, and nuts. This hunter-gatherer lifestyle meant that people relied on the natural availability of resources rather than cultivating or raising food themselves. The shift to agriculture allowed for the controlled growing of crops and raising of animals, fundamentally changing human societies.
4.
Hunters and gatherers lived in small groups.
Correct Answer
A. True
Explanation
Hunter-gatherer societies typically lived in small, nomadic groups. This allowed them to move easily in search of food and resources, as they relied on hunting animals and gathering plants in the wild. The smaller group sizes made it easier to manage resources and move efficiently to new locations when necessary.
5.
The __________ hunted game or fished and the ______________ collected berries, nuts, and roots.
Correct Answer
A. Men; women
Explanation
In most traditional hunter-gatherer societies, roles were generally divided based on gender. Men typically hunted game or fished to provide animal-based food sources, while women often gathered edible plants, such as berries, nuts, and roots. This division allowed groups to efficiently use resources and skills for survival. However, these roles could vary by culture and environment, with some societies showing more flexibility in food-gathering roles.
6.
There are still hunters and gatherers in the world today.
Correct Answer
A. True
Explanation
While modern agriculture and urbanization have changed the lifestyle for most of the global population, there are still hunter-gatherer societies existing today. Examples include certain Indigenous groups in the Amazon rainforest, the Hadza people in Tanzania, and some groups in Papua New Guinea and the Arctic. These communities continue to rely on traditional methods of hunting, fishing, and gathering for survival, although many are also adapting due to external influences and pressures on their environments.
7.
What are the two types of cultivation (NOT types of agriculture)?
Correct Answer
A. Shifting cultivation and intensive cultivation
Explanation
The correct answer is "Shifting cultivation and intensive cultivation." Shifting cultivation involves moving to new land once soil fertility declines, commonly in traditional agricultural societies. Intensive cultivation, on the other hand, involves maximizing output from a given area, often through the use of fertilizers and efficient crop management. These approaches focus on how land is cultivated rather than the agricultural methods or economic types involved.
8.
Which of the following best describes intensive cultivation?
Correct Answer
B. A method of agriculture that uses small plots of land and high levels of labor and input to maximize yield.
Explanation
The correct answer is A method of agriculture that uses small plots of land and high levels of labor and input to maximize yield. Intensive cultivation involves maximizing productivity from a small area of land, often through practices like the use of fertilizers, irrigation, and labor-intensive planting techniques. This approach contrasts with extensive cultivation, which typically involves larger land areas with lower input levels.
9.
Agriculture probably had one hearth.
Correct Answer
B. False
Explanation
Agriculture did not originate from a single hearth; rather, it developed independently in multiple regions around the world. Archaeological evidence suggests that the domestication of plants and animals occurred in various places, including the Fertile Crescent, East Asia, Sub-Saharan Africa, and the Americas. Each of these regions developed its own agricultural practices based on local resources and environmental conditions.
10.
Which of the following is/are the primary hearths of vegetative planting? (Check all that apply)

These regions played pivotal roles in the origins of agriculture and the domestication of significant crops.
14.
Seed agriculture diffused in all compass directions- northward, eastward, southward, and westward- from the hearth in China.
Correct Answer
A. True
Explanation
Seed agriculture diffused in all compass directions—northward, eastward, southward, and westward—from its hearths, including the one in China. As agricultural practices developed, the knowledge of cultivating crops and the seeds themselves spread to neighboring regions and eventually to more distant areas, contributing to the global agricultural landscape we see today. This diffusion was influenced by trade, migration, and cultural exchange, allowing diverse regions to adopt seed agriculture practices over time.
15.
When was seed agriculture starting to become widely practiced in the Western Hemisphere?
Correct Answer
C. When the Europeans brought agriculture with them from Europe
Explanation
Seed agriculture began to become widely practiced in the Western Hemisphere after European colonization in the late 15th and early 16th centuries. Europeans introduced various agricultural practices and crops from their homelands, which led to the establishment of seed agriculture in the Americas. Prior to this, indigenous peoples had their own forms of agriculture, but the introduction of European farming techniques and crops significantly transformed agricultural practices in the region.
16.
What are the primary differences between agriculture practices in the world and those of what two types of regions/countries?
Correct Answer
E. MDCs and LDCs
Explanation
The primary differences between agricultural practices in the world are often characterized by the distinction between More Developed Countries (MDCs) and Less Developed Countries (LDCs). MDCs typically engage in advanced agricultural techniques, industrialized farming, and high yields due to better access to technology, resources, and infrastructure. In contrast, LDCs often rely on traditional farming practices, subsistence agriculture, and may face challenges such as limited access to technology, capital, and markets, leading to lower productivity levels. This divide influences the types of crops grown, farming methods used, and the overall agricultural economy of each region.
17.
What type of agriculture is practiced to produce food for sale off the farm?
Correct Answer
A. Commercial
Explanation
Commercial agriculture is practiced to produce food and other agricultural products primarily for sale off the farm. This type of agriculture involves large-scale production and typically employs modern farming techniques, technology, and practices to maximize yield and efficiency. Unlike subsistence agriculture, where farmers grow food primarily for their own consumption, commercial agriculture focuses on generating profit and meeting market demands, often resulting in specialized crops and livestock production aimed at local or global markets.
18.
What type of agriculture is practiced to feed the farmer and the farmer's family?
Correct Answer
B. Subsistence
Explanation
Subsistence agriculture is practiced to feed the farmer and the farmer's family. In this type of agriculture, farmers grow a variety of crops and raise livestock primarily for their own consumption rather than for sale in the market. The focus is on producing enough food to meet the household's needs, often leading to a diverse range of crops being cultivated to ensure food security. Subsistence agriculture can involve traditional farming methods, and it is common in many rural and developing areas where farmers rely on their own production to sustain their families.
19.
In LDCs, the production of food to sell to the government or private firms is the main priority.
Correct Answer
B. False
Explanation
In Less Developed Countries (LDCs), the primary focus is often on subsistence agriculture, where farmers produce food mainly for their own consumption and that of their families. While there may be some production for sale to the government or private firms, this is generally not the main priority for most small-scale farmers in LDCs. Many LDCs face challenges such as limited access to markets, resources, and technology, which can hinder large-scale production for sale. Instead, the emphasis is usually on meeting local food needs and ensuring food security for their households.
20.

21.
Which of the following options accurately completes the statement regarding the level of involvement in farming among populations in More Developed Countries (MDCs) compared to Less Developed Countries (LDCs)?
Correct Answer
B. Low in MDCs; High in LDCs
Explanation
In More Developed Countries (MDCs), the level of involvement in farming is generally low, as these economies are more industrialized and rely less on agriculture. Conversely, in Less Developed Countries (LDCs), the level of involvement in farming is high, as agriculture remains a critical part of the economy and livelihood for a large portion of the population.
22.
The low percentage of farmers in MDCs explains why MDCs are not able to provide LDCs with food.
Correct Answer
B. False
Explanation
The low percentage of farmers in More Developed Countries (MDCs) does not prevent MDCs from providing food to Less Developed Countries (LDCs). Although a smaller proportion of the population in MDCs is directly involved in farming due to advancements in agricultural technology and efficiency, these countries typically produce a surplus of food. This surplus, combined with efficient transportation and distribution systems, enables MDCs to export food to LDCs when needed. Therefore, the ability to provide food is not solely dependent on the percentage of the population involved in agriculture.
23.
The number of farmers have decreased during the twentieth century.
Correct Answer
A. True
Explanation
The number of farmers has generally decreased during the twentieth century due to several factors, including industrialization, urbanization, and advancements in agricultural technology. As farming techniques became more efficient and mechanized, fewer farmers were needed to produce the same amount of food. This led to a consolidation of farms and a shift in labor from rural agricultural work to urban industries and services. Consequently, while agricultural production has increased, the number of people employed directly in farming has declined significantly.
24.
Farmers in MDC primarily use what for power? (Check all that apply)

B. Derwent Whittlesey
Explanation
Derwent Whittlesey was a geographer known for his work on agricultural regions. He developed a widely referenced map that categorized various agricultural practices around the world based on their distribution and characteristics. His research helped to understand the differences between subsistence agriculture (which primarily supports the farmer's family) and commercial agriculture (which produces goods for sale), illustrating how geography influences farming practices.
30.
Excluding regions where agriculture is nonexistent, how many agricultural regions did Whittlesey identify on his map?
Correct Answer
C. 11
Explanation
Whittlesey identified 11 distinct agricultural regions across the globe in his studies, excluding areas where agriculture does not occur. These regions include both those predominantly in Less Developed Countries (LDCs) and More Developed Countries (MDCs). His classifications helped to highlight the diversity of agricultural practices and their geographical distribution.
31.
Derwent Whittlesey classified agricultural practices primarily based on:
Correct Answer
B. Climate
Explanation
Climate plays a critical role in agriculture as it affects the types of crops that can be successfully cultivated and whether livestock can be raised in a particular region. Factors such as temperature, precipitation, and seasonal variations determine the growing conditions for crops and the feasibility of animal husbandry. Whittlesey's classification of agricultural practices reflects the importance of climate in shaping agricultural systems around the world.
32.
In what kind of a region is shifting cultivation practiced?
Correct Answer
A. Humid Low-Latitude
Explanation
Shifting cultivation, also known as slash-and-burn agriculture, is primarily practiced in humid low-latitude regions characterized by high rainfall and warm temperatures, which support dense tropical vegetation. These conditions enable farmers to clear plots of land for cultivation, grow crops for several years, and then allow the land to regenerate during a fallow period. This agricultural method thrives in environments where soil fertility can be temporarily restored, making humid low-latitude areas ideal for such practices. Other regions, such as dry, cold mid-latitude, or polar areas, lack the necessary climate and ecological conditions for effective shifting cultivation.
33.
A region with a humid low-latitude climate would have:
Correct Answer
A. High temperatures with abundant rainfall
Explanation
A humid low-latitude climate is characterized by high temperatures, typically exceeding 25°C (77°F), and abundant rainfall, often surpassing 1,500 mm (59 inches) annually. This climate, commonly found near the equator, allows for consistent warmth and high humidity levels, leading to lush vegetation and diverse ecosystems, such as rainforests. The combination of warm temperatures and plentiful precipitation creates ideal conditions for rich biodiversity, distinguishing these regions from cooler or drier climates that do not exist in low-latitude areas.
34.
Why is shifting cultivation called shifting cultivation instead of shifting agriculture? What is the primary difference between the two?
Correct Answer
E. Both scale and intensity
Explanation
Shifting cultivation is called "shifting cultivation" rather than "shifting agriculture" primarily due to the scale and intensity of the practices involved.
Scale: Shifting cultivation typically refers to small-scale subsistence farming practiced by individuals or families within specific communities. It involves the rotation of fields, allowing land to rest and recover after a period of cultivation. In contrast, the term "agriculture" often implies larger-scale operations that may include commercial farming with more extensive land use.
Intensity: Shifting cultivation is characterized by its low intensity, where farmers cultivate a plot of land for a few years before shifting to another plot, allowing the previously used land to regenerate naturally. This method contrasts with conventional agriculture, which usually involves continuous cultivation of the same land with more intensive practices, such as the use of fertilizers and irrigation.
35.
Specifically, how do farmers clear the land for shifting cultivation?
Correct Answer
D. Slashing the vegetation and burning the debris
Explanation
Farmers clear land for shifting cultivation by slashing the vegetation and burning the debris. Initially, they cut down trees, shrubs, and grasses using tools like machetes or hoes, which prepares the area for planting. After the vegetation dries, they burn it, resulting in ash that enriches the soil with nutrients beneficial for crops. This burning also helps control pests and weeds, facilitating easier land preparation. This method supports the sustainability of shifting cultivation, as farmers typically rotate to new plots after a few years, allowing previously cultivated areas to naturally regenerate.
36.
In shifting cultivation, exhausted soil is left fallow for a time period until it is ready for use again.
Correct Answer
A. True
Explanation
True. In shifting cultivation, once the soil becomes exhausted from continuous cropping, it is left fallow for a specific period. During this fallow period, the land is not cultivated, allowing it to recover its fertility naturally. This practice enables the soil to regain nutrients and support the growth of vegetation, which can help restore its productivity for future farming. The length of the fallow period can vary depending on environmental conditions and the specific practices of the farmers.
37.
What is the land cleared by slash-and-burn agriculture called?
Correct Answer
B. Swidden
Explanation
In slash-and-burn agriculture, a piece of land is cleared of vegetation through cutting and burning, creating a temporary agricultural plot known as "swidden." This practice allows farmers to utilize the nutrients released from the burnt vegetation to cultivate crops for a limited time before moving to another area, allowing the cleared land to recover.
38.
In shifting cultivation, hoes, plows, and animals are used to prepare the fields for planting.
Correct Answer
B. False
Explanation
In shifting cultivation, the primary method of land preparation involves slash-and-burn techniques rather than the use of hoes, plows, and animals. Farmers typically clear the land by cutting down vegetation and burning it to enrich the soil. They may use simple hand tools, such as machetes or hoes, for planting but do not generally employ plows or draft animals in the traditional sense. The focus is on utilizing the nutrients from the ash of the burned vegetation for a short period before moving on to another area.
39.
Which of the following is NOT a reason why fields are abandoned in shifting cultivation?
Correct Answer
C. Water scarcity
Explanation
In shifting cultivation, fields are typically abandoned due to nutrient depletion, infertile soil, and rapid weed growth. The soil becomes less fertile after continuous cropping, leading to nutrient depletion, which can prompt farmers to move to a new area. Additionally, rapid weed growth can make it difficult to cultivate the land effectively. However, water scarcity is not a primary reason for abandoning fields in this agricultural system. Instead, shifting cultivators often choose new locations based on soil fertility rather than water availability, as they typically rely on the natural moisture present in the humid low-latitude regions where shifting cultivation is practiced.
40.
In shifting cultivation, if a village abandons a patch of land, the people will not closely take care of the land until it is time for them to reuse the land after the soil is replenished.
Correct Answer
B. False
Explanation
In shifting cultivation, when a village abandons a patch of land, the farmers leave it fallow for a certain period to allow the soil to replenish its nutrients naturally. During this time, the land is typically not actively cared for or cultivated. Instead, the farmers focus on other areas for cultivation until the abandoned land can be reused. This practice relies on the natural regeneration of the vegetation, which helps restore soil fertility and prepares it for future agricultural use. The fallow period is essential for maintaining the sustainability of the shifting cultivation system.
41.
The Kayapo people of the Amazon plant their crops in what shape?
Correct Answer
C. Circle
Explanation
The Kayapo people of the Amazon practice a form of shifting cultivation, and they typically plant their crops in circular shapes. This method, known as the "circle planting" technique, allows them to optimize the use of space and manage the surrounding vegetation effectively. The circular arrangement helps in creating a microenvironment that can support a diverse array of crops while also facilitating easier access for tending and harvesting. This traditional agricultural practice reflects their deep understanding of the local ecology and enhances biodiversity in their farming systems.
42.
Farmers in MDCs grow (one/many) crop(s) over a wide area. Farmers in LDCs grow (one/many) crop(s) over a wide area.
Correct Answer
C. Farmers in MDCs grow many crops over a wide area. Farmers in LDCs grow one crop over a wide area.
Explanation
In More Developed Countries (MDCs), farmers often engage in commercial agriculture, where they grow multiple crops over large areas to maximize profit and meet market demands. In contrast, in Less Developed Countries (LDCs), farming practices are typically subsistence-oriented, focusing on growing a single crop over a wide area to meet the basic food needs of the family or community. This difference reflects varying agricultural practices influenced by economic conditions, technological advancements, and available resources.
43.
Shifting cultivation occupies about _________% of the world's land area and about __________% of the world's population.
Correct Answer
C. 20% of the world's land area and 5% of the world's population.
Explanation
Shifting cultivation, also known as slash-and-burn agriculture, is a form of subsistence farming practiced in tropical regions, and it covers approximately 20% of the world's land area. However, it is practiced by about 5% of the world's population, as it is primarily utilized by indigenous communities and rural populations in specific regions. This highlights the extensive land use for shifting cultivation compared to the relatively small percentage of people who rely on this agricultural method for their livelihood.
44.
What do critics say about shifting cultivation? (Check all that apply)
Correct Answer(s)
A. Shifting cultivation is an inefficient way to feed people in LDCs
C. Shifting cultivation is not an effective use of land
Explanation
Critics of shifting cultivation argue that it is an inefficient method for feeding populations in less developed countries (LDCs) due to its reliance on small plots of land and extended fallow periods, which may not yield sufficient food for larger communities. They also claim that this practice is not an effective use of land, as it involves relocating from one plot to another, leading to underutilization of fertile areas. While shifting cultivation is culturally significant and can maintain biodiversity, critics tend to emphasize its potential negative impacts on land degradation when not managed sustainably, making the notion that it is environmentally friendly a contested perspective.
45.
What is/are the difference(s) between pastoral nomadism and ranching? (Check all that apply)
Correct Answer(s)
A. Pastoral nomadism is a form of subsistence agriculture whereas ranching is a form of commercial agriculture.
C. Nomads migrate a longer distance with their livestock than ranchers.
D. Ranchers raise livestock but nomads grow crops as well as livestock.
Explanation
Pastoral nomadism, a form of subsistence agriculture practiced in less developed countries (LDCs), involves nomads who frequently migrate with their livestock, following water sources and seasonal patterns through transhumance. They typically do not kill their animals, as herd size signifies power and prestige, but will consume them if they die. In contrast, ranching is a commercial agriculture practiced in more developed countries (MDCs), where ranchers raise livestock in designated areas without migrating. While nomads may also grow crops—often with the help of women, children, or hired labor—they may temporarily settle in one area until the soil is depleted or conditions worsen, prompting migration in search of food and water.
46.
Intensive subsistence agriculture means that farmers must use a larger piece of land to produce food.
Correct Answer
B. False
Explanation
False. Intensive subsistence agriculture refers to farming practices that use smaller plots of land but require a significant amount of labor and inputs to maximize yield. Farmers focus on high levels of productivity per acre, often employing techniques such as crop rotation, intercropping, and intensive irrigation to produce sufficient food for their families or local markets. Thus, it is characterized by its focus on maximizing output from limited land rather than requiring larger land areas.
47.
Wet rice is first planted on __________ and then transferred to __________ to promote growth.
Correct Answer
A. Dry land; Wet land
Explanation
Wet rice cultivation typically begins with planting seeds in dry land, often in seedbeds, where they can germinate. Once the seedlings have grown to a certain height, they are then transferred to wet land, or flooded fields, to promote optimal growth and yield.
48.
The flooded field in which wet rice is grown is called a paddy.
Correct Answer
B. False
Explanation
True. The flooded field in which wet rice is grown is called a paddy. The term "paddy" originates from the Malay word "padi," which refers to unhusked rice. In wet rice cultivation, paddies are created by flooding the fields with water, which helps to create a suitable environment for rice plants to grow. This method not only supports the rice plants during their critical growth stages but also helps to suppress weed growth and provides essential nutrients from decomposed organic matter. Paddies can vary in size and are often surrounded by bunds (earth embankments) to retain water. The management of water levels in these paddies is crucial, as it affects the health of the rice plants and the overall yield.
49.
Which of the following are the steps of harvesting rice seeds from the chaff, or the husks? (Select all that apply)
Correct Answer(s)
A. Cutting the rice stalks
B. Threshing the rice to separate the grains from the chaff
C. Drying the grains in the sun
D. Winnowing to remove the husks from the grains
E. Storing the harvested seeds in airtight containers
Explanation
The process of harvesting rice seeds from the chaff involves several key steps. First, farmers cut the mature rice stalks at the base to gather the plants. Next, they thresh the rice, which separates the edible grains from the inedible husks. After threshing, the grains are dried in the sun to reduce moisture content, which is crucial for storage. The next step is winnowing, where wind or air is used to blow away the lighter chaff, leaving the heavier rice grains behind. Finally, the cleaned and dried rice seeds are stored in airtight containers to protect them from pests and moisture until needed for planting or consumption.
50.
The process of obtaining two harvests per year from the same field is called:
Correct Answer
A. Single cropping
Explanation
Double cropping refers to the agricultural practice of growing two different crops on the same piece of land within a single growing season. This method maximizes land use and increases food production, which is particularly important in regions where land is scarce. Single cropping (option A) involves planting only one crop per year, while crop rotation (option C) is the practice of alternating the types of crops grown in a particular area across seasons to maintain soil fertility. Intercropping (option D) refers to growing two or more crops in proximity to each other, which can enhance yield and biodiversity but does not necessarily involve harvesting two crops from the same field in one year.
