19 Which set correctly lists the three main pillars of sustainability?

20 How many Sustainable Development Goals were adopted by the United Nations?

21 A new highway reduces travel time but fragments a wildlife habitat and increases nearby noise levels. Which interpretation best reflects the environmental perspective?

22 Residents report that a lake has become unsuitable for recreation after untreated sewage caused algal growth and foul odors. Which relationship is most directly illustrated?

23 A city replaces a wetland with buildings, after which flooding increases and bird populations decline. Which environmental components are most directly involved?

24 Which observation best demonstrates an interaction between biotic and abiotic components of the environment?

25 Sulfur dioxide released into the air forms acid rain that lowers the pH of a lake and harms fish. Which sequence of Earth-sphere interactions is most accurate?

26 During heavy rain, exposed soil from a construction site enters a river and reduces aquatic plant growth. Which three spheres interact most directly?

27 A town wants to control air pollution without unfairly burdening low-income workers. Which team would provide the most appropriate multidisciplinary assessment?

28 Before approving a dam, planners study fish habitats, displaced communities, electricity demand, and legal requirements. Why is this approach appropriate?

29 A forest produces about tonnes of new timber each year. Which annual harvesting plan is most consistent with ecological sustainability, assuming other conditions remain stable?

30 A university wants to make its cafeteria more sustainable. Which action best applies a life-cycle perspective?

31 Which urban policy best reflects sustainable development?

32 A coastal community must choose a development proposal. Which proposal best meets present needs without undermining future generations?

33 An island has liters of renewable freshwater available annually. If each resident requires liters per year, what is the water-based carrying capacity?

34 A deer population remains above the carrying capacity of a grassland for several years. What outcome is most likely if no limiting factor changes?

35 A farming region adopts drip irrigation and soil-moisture monitoring, allowing the same water supply to support more crops. How does this affect carrying capacity?

36 A solar project lowers emissions and earns a profit but displaces residents without consultation or compensation. Which sustainability pillar is most clearly neglected?

37 Which business decision provides the most balanced support for the environmental, social, and economic pillars of sustainability?

38 A program installs solar-powered pumps that provide safe drinking water in villages. Which pair of Sustainable Development Goals is most directly advanced?

39 A city introduces separate waste collection, repairs reusable goods, and converts organic waste into compost. Which goal is addressed most directly?

40 A government measures progress only by counting newly planted trees, without checking species diversity, survival rates, or restored habitat area. What is the main weakness of this SDG assessment?

41 A coastal city constructs a seawall to reduce storm-surge exposure. The wall protects urban property but accelerates erosion downstream, alters sediment transport, and encourages further construction in the protected zone. Which interpretation best reflects the environmental perspective?

42 Two valleys receive the same annual rainfall and contain similar soils. One experiences severe flooding after forest conversion and settlement expansion, while the other does not. Which conclusion is most defensible?

43 A pesticide applied to cropland binds to soil particles, enters a river during erosion, accumulates in fish, and affects fishing-community income. Which sequence of environmental components is most accurate?

44 An assessment records falling groundwater levels, reduced wetland vegetation, migration of farming households, and a new irrigation-pricing rule. How should these indicators be classified, respectively?

45 Permafrost thaw releases methane, which strengthens atmospheric warming and causes additional thaw. Which Earth-sphere coupling directly initiates and then amplifies this feedback?

46 A volcanic eruption injects sulfur dioxide into the atmosphere, forms sulfate aerosols, reduces incoming solar radiation, and temporarily lowers ocean-surface temperature. Which ordering best represents the dominant cross-sphere pathway?

47 A proposed dam has positive net monetary benefits but would displace an Indigenous community and fragment a migratory-fish habitat. Which study design best reflects the multidisciplinary nature of environmental studies?

48 Researchers must recommend a groundwater policy under uncertain recharge estimates and unequal access to wells. Which combination of disciplines addresses both the physical limit and the allocation problem most directly?

49 A region maintains constant total wealth by replacing a destroyed wetland with financial assets of equal estimated monetary value. The wetland had an irreplaceable flood-regulation threshold. Which sustainability interpretation rejects the substitution?

50 A fishery keeps annual harvest below estimated population growth, yet fish size and genetic diversity decline because only the largest fish are captured. What does this demonstrate?

51 A government subsidizes efficient air conditioners. Electricity used per unit falls by 30%, but lower operating costs increase ownership and usage enough that total electricity demand rises. Which policy conclusion best follows?

52 Project X raises average income substantially but increases irreversible ecosystem loss and leaves the poorest households worse off. Project Y raises income moderately, preserves ecosystem functions, and improves the position of the poorest. Under an equity-sensitive sustainable development framework, which judgment is strongest?

53 An island aquifer receives million of renewable recharge annually. To prevent saltwater intrusion, withdrawals cannot exceed of recharge. Domestic demand is per resident per year, while agriculture requires a fixed million annually. Ignoring other uses, what is the maximum sustainable population?

54 A population follows with . Habitat loss suddenly reduces to while and . What does the model predict immediately after the change?

55 A city imports most of its food and exports its waste, allowing its population to exceed the productive and assimilative capacity of its local land. Which statement best characterizes the city's carrying capacity?

56 A recycling plant is profitable and reduces landfill use, but exposes low-income workers to unsafe pollutant levels. Which sustainability diagnosis is most accurate?

57 A city compares four transport plans. Which plan most clearly represents integration rather than a trade-off among the environmental, social, and economic pillars?

58 A country expands irrigated agriculture to advance SDG 2, but the program depletes aquifers, increases fertilizer runoff, and excludes small farmers. Which SDG principle is most directly violated?

59 National access to safely managed drinking water rises from to , but access remains in remote minority communities. Which interpretation best reflects the 2030 Agenda's commitment to leave no one behind?

60 A climate project reports avoided emissions but does not count emissions embodied in imported equipment, and it displaces land users without consultation. Which evaluation approach is most consistent with the SDG framework?
