In coastal municipalities facing persistent droughts, regional water authorities historically funded large-scale ocean desalination plants to secure municipal fresh water supplies. However, recent economic assessments reveal that high electricity costs and rapid membrane degradation make long-term desalination operations financially unsustainable without ongoing municipal subsidies. Because reclaimed water filtration systems consume sixty percent less energy and achieve comparable purity standards, city planners argue that municipal investments should immediately pivot entirely toward expanding local wastewater recycling infrastructure. Therefore, municipal councils ought to reject all upcoming budget proposals requesting capital allocations for new desalination facilities.
In the argument presented, the bolded statement plays which of the following roles?
- AIt is a premise offered directly to support the main conclusion that municipal councils should reject new desalination capital allocations.
- BIt expresses the main conclusion of the argument regarding how municipal councils should allocate future water infrastructure budgets.
- It provides background information regarding a historical practice that sets up the context for the situation the argument seeks to address.Cevap
- DIt introduces a counterargument that the author attempts to refute using evidence about energy consumption.
- EIt functions as an intermediate conclusion derived from the observation that desalination facilities are financially unsustainable.
