Over the last decade, the transition towards a low-carbon economy has significantly reshaped the domestic energy labor market. While employment in traditional coal-mining and petroleum-extraction regions has fallen sharply, the offshore wind, solar development, and battery manufacturing sectors have experienced rapid expansion. Although government-funded 'green transition academies' have offered subsidized retraining programs to former fossil-fuel workers, geographic immobility and skill mismatches mean that several former coal and oil hubs continue to suffer from localized structural unemployment. Concurrently, overall national employment has reached record highs, driven primarily by growth in the technology and hospitality sectors.
Which one of the following can be inferred from the text?
The occupational and geographic mobility of displaced fossil-fuel workers is frictionless.
Overall national employment has fallen due to the contraction of the traditional energy sector.
The domestic energy sector has experienced a structural reallocation of labor.
Government-funded retraining programs have successfully eliminated structural unemployment in former energy-producing regions.
