The answers are (B) service jobs, (C) professional jobs, and (D) retail jobs.
Manufacturing jobs have generally been on the decline in the United States since the 1970s. This decline is due to several factors, including automation, outsourcing, and the shift of manufacturing to countries with lower labor costs.
Service jobs have been on the rise since the 1970s. The service sector includes a wide range of jobs such as healthcare, education, finance, and hospitality. The growth in this sector is attributed to the increasing demand for services and the shift from a manufacturing-based economy to a service-based economy.
Professional jobs, which often require higher education and specialized skills, have also been on the rise. This category includes jobs in fields such as information technology, engineering, law, and medicine. The rise in professional jobs is linked to technological advancements and the increasing complexity of the modern economy.
Retail jobs have seen growth as well, particularly with the expansion of consumer spending and the proliferation of retail outlets. However, it's worth noting that the retail sector has faced challenges in recent years due to the rise of e-commerce and changing consumer habits.
