What does the GPSC primarily monitor in the telecommunications and natural gas markets?

The correct answer highlights the role of the Georgia Public Service Commission (GPSC) in overseeing the telecommunications and natural gas markets, specifically focusing on consumer rates and service quality. The GPSC is tasked with ensuring that utility companies provide reliable services at reasonable rates, which is crucial for protecting consumers and ensuring fair access to essential services.

Monitoring consumer rates allows the GPSC to ensure that the charges levied on customers are not excessively high and align with the cost of service delivery. Additionally, service quality oversight ensures that companies maintain adequate standards in their operations, directly impacting the consumer experience. Ensuring a balance between acceptable rates and high service quality reflects the GPSC's mission of regulating utilities in the interest of the public.

The other options do play roles in the industry but are not the primary focus of the GPSC. Worker wages, technological advancements, and market share of competitors are important aspects of the broader economic landscape, but they do not fall within the direct purview of GPSC's regulatory framework concerning telecommunications and natural gas markets.
