1. A secondary source on urban food supply states that as land values rise near the central business district, agriculture persists only when it generates very high returns per hectare (such as specialty flowers and greenhouse herbs). Lower-return uses relocate outward or are replaced by housing and commercial development. Which of the following best explains the spatial pattern of agriculture described in the excerpt?
2. A secondary source on women in agriculture argues that women's productivity can be limited by unequal access to land titles, extension services, and inputs such as fertilizer or irrigation. The author notes that development programs often target "household heads," which can exclude women farmers even when they do much of the work. Which statement best reflects this explanation?
3. Secondary-source excerpt (Fertile Crescent hearth): Archaeobotanical and zooarchaeological evidence places early cultivation and herding within a broad arc from the Levant through northern Mesopotamia into the Zagros foothills. Rather than a single "center," researchers describe a mosaic of communities experimenting with emmer, einkorn, barley, sheep, and goats, with practices moving along river valleys and steppe margins. Diffusion was uneven: some neighboring groups adopted selected crops or animals, while others maintained mixed foraging strategies for long periods, constrained by rainfall variability and soil conditions. Which of the following best explains the spatial pattern of agricultural origins described in the excerpt?
4. A 2024 secondary-source excerpt on "ethnoburbs" explains that affluent Korean and Vietnamese migrants in suburban California establish churches, restaurants, and tutoring centers that attract customers beyond their own communities. The author argues that cultural diffusion here follows a hierarchical pattern within the metro area (from prosperous suburbs into regional media and retail), but the underlying cause is sustained migration and settlement. Which option best identifies the contemporary cause of diffusion?
5. A public health department creates a map showing rates of asthma hospitalization by neighborhood, using darker shading for higher rates to reveal spatial variation. A separate map of the same city shows street names, transit lines, and landmarks for general orientation. Which option correctly classifies the two maps?
6. Secondary source excerpt (global economy change—growth of service economies in developed countries, 75–125 words): In many developed economies, employment growth has shifted toward services such as health care, education, finance, software, and logistics. As manufacturing became more automated or moved abroad, metropolitan regions attracted corporate headquarters, research centers, and specialized business services. This transition increased demand for highly educated workers, while also expanding lower-wage service work in retail, caregiving, and food preparation. The changing mix of jobs has contributed to widening income polarization within cities and suburbs, even as overall GDP may continue to rise. Which change from the global economy is most clearly described?​
7. Secondary source excerpt (about 85–115 words): Analysts often distinguish between "open" and "closed" borders as policy choices rather than permanent geographic facts. Open borders may allow relatively easy legal entry, streamlined customs, and frequent cross-border commuting, usually supported by agreements that coordinate security and labor rules. Closed borders emphasize restriction through walls, expanded patrols, and tight visa controls, often justified by security concerns or domestic political pressures. However, even "open" borders still regulate movement through documentation, and "closed" borders often contain exceptions for trade corridors or diplomatic travel. Which option best captures the function being discussed?
8. A country has low CDR, quickly falling CBR, and positive natural increase. DTM stage?
9. A secondary source describing dependency theory emphasizes that development strategies can deepen underdevelopment when they rely on exporting a single commodity whose price is volatile, especially when foreign firms control processing and shipping. In a scenario, a country expands oil exports; GDP rises, but local manufacturing shrinks as the currency strengthens and profits flow to foreign contractors. Which dependency-theory concept is most consistent with this outcome?
10. Secondary source excerpt (resistance and preservation): A regional government funds bilingual signage, community radio, and curriculum in a minority language after surveys show rapid language shift toward the national language. Policy documents state the goal is to increase the language's prestige and daily utility so families will keep using it at home and in public. Critics argue the measures challenge long-standing centralization that favored a single national identity. Which effect of cultural diffusion is best represented?
11. A secondary source excerpt emphasizes multi-scalar analysis: local decisions can be constrained by broader-scale policies and markets. A student examines food insecurity by looking at (1) grocery store access by neighborhood, (2) state minimum-wage laws, and (3) global wheat prices. Which conclusion best reflects multi-scalar thinking?
12. Secondary source excerpt (18th–19th centuries): In Britain, Parliament-backed enclosure consolidated scattered strips and common lands into fenced, privately owned farms. Landlords and wealthier tenant farmers gained clearer title and could more easily invest in drainage, selective breeding, and new crop rotations. Yet enclosure also reduced customary rights to graze animals or gather fuel, pushing many smallholders and cottagers off the land and into wage labor or migration. Which statement best explains how enclosure reshaped rural settlement and land use patterns during the Second Agricultural Revolution?
13. A recent synthesis in agricultural geography notes that fertilizer-dependent yield gains have been accompanied by rising nitrogen and phosphorus losses from farms into waterways. The excerpt emphasizes that nutrient runoff varies by soil type, rainfall intensity, drainage infrastructure, and farm capitalization, and that downstream costs often fall on municipalities and fisheries rather than producers. It also highlights tradeoffs: tighter nutrient limits can raise production costs and shift cropping patterns, while lax regulation can intensify eutrophication and drinking-water treatment burdens. The excerpt best illustrates which of the following challenges to contemporary agriculture?
14. Secondary-source excerpt (about 80–110 words): Human trafficking involves the recruitment and movement of people through force, fraud, or coercion for the purpose of exploitation, such as forced labor or sexual exploitation. Trafficked persons may cross borders or remain within a country, and their movement can be hidden within broader migration streams. Unlike many voluntary migrants who plan and consent to relocation for work or family reasons, trafficking centers on the absence of meaningful consent and the presence of coercion. Because trafficking is a crime, responses involve law enforcement as well as victim protection and social services. Which option best distinguishes trafficking from voluntary labor migration?
15. A textbook excerpt argues that economic measures alone (like GDP per capita) can misrepresent development: a country may have high average income while many people lack access to clean water, schooling, or healthcare. The excerpt recommends using multiple indicators to understand quality of life. Which conclusion aligns best with this argument?
16. A secondary source describes Green Revolution adoption as tied to market integration: farmers who could sell surplus grain and access input suppliers were more likely to invest in HYVs, fertilizer, and machinery. In contrast, remote areas with poor roads and limited storage faced higher transaction costs and slower adoption. Which of the following best explains the Green Revolution pattern described in the excerpt?
17. A comparative politics textbook explains that in a federal system, sovereignty is constitutionally divided between a national government and subnational units (such as states or provinces), each with some independent lawmaking authority. In a unitary system, the central government is the primary source of authority and may delegate powers to local governments, but those powers can typically be altered or revoked by the center. Based on this description, which scenario best illustrates a federal system?
18. A secondary-source excerpt on air pollution in Eastport explains: "Despite tighter vehicle standards, nitrogen oxides remain high near port terminals where ships, trucks, and warehouses cluster. The report highlights 'hot spots' created by zoning that concentrates logistics in specific corridors, and it notes that residents in adjacent neighborhoods have limited political leverage to demand mitigation. It argues that cleaner technology must be paired with land-use reform, freight management, and community participation to reduce unequal exposure." Which choice best reflects this argument?
19. A secondary source on terracing in mountainous farming regions describes the construction of stepped fields that slow runoff and retain soil on slopes. The author links terraces to reduced erosion and improved water infiltration in many settings, but notes that building and maintaining stone walls and channels requires substantial labor and coordination. The analysis adds that terrace performance depends on rainfall intensity, maintenance frequency, and land tenure; neglected terraces may fail and concentrate erosion. The consequences therefore vary across communities and time. Which of the following is the most significant environmental consequence of the agricultural practice described?
20. A river-basin assessment describes long-established irrigation districts that divert water during dry seasons to stabilize vegetable production. In upstream reaches, increased withdrawals reduce in-stream flows and can warm river temperatures, affecting aquatic habitat; downstream, farmers report less reliable deliveries during drought years. The assessment also notes that improved drip systems and lined canals can reduce losses and partly mitigate impacts, though adoption varies by cost and governance. The overall effect depends on climate variability, allocation rules, and efficiency investments. The excerpt best illustrates which of the following consequences of the practice described?
