44 Two cities have equal populations. City X has high-density housing and mass transit, while City Y has dispersed housing, private vehicles, and fragmented infrastructure. Which conclusion is most defensible?

45 An intervention reduces deaths from indoor air pollution but leaves many survivors with chronic respiratory disability. Which metric is best suited to evaluating both effects together?

46 After flooding, a settlement experiences diarrhoeal disease, mosquito proliferation, and loss of access to health services. Which response most directly reflects an integrated environmental-health strategy?

47 A forest project is rejected because an endemic species is considered valuable even if it provides no known benefit to humans. Which ethical position most directly supports the decision?

48 A government permits depletion of a unique wetland because the revenue will finance roads and schools of equivalent monetary value. Which principle most strongly challenges the assumption that this substitution is ethically sufficient?

49 An awareness campaign raises knowledge about household waste segregation, but observed segregation rates remain unchanged. Which redesign is most likely to close this knowledge-action gap?

50 A sacred grove protects old-growth vegetation but excludes customary collection by some marginalized residents. Which assessment best integrates conservation and equity?

51 A tribal community manages a forest through seasonal harvest restrictions, habitat taboos, and collective monitoring. A conservation plan instead removes the community and centralizes enforcement. What key risk does the plan create?

52 A company begins constructing an industrial unit without a required prior environmental clearance and argues that compensatory measures can be imposed after construction. Which legal principle most directly undermines this argument?
