Final answer:
People employed by transportation agencies usually work in administration or engineering, overseeing operations and designing infrastructure, whereas sales and education are less connected to these agencies.
Step-by-step explanation:
Individuals primarily employed by federal, state, and local transportation agencies typically follow career pathways aligned with administration, engineering, and various roles concerning transportation infrastructure. Those in administration may oversee operations and manage public resources, while engineers could design and maintain infrastructure such as roads, bridges, and transit systems. Neither of these pathways typically build bridges and water systems on their own but may have responsibilities relating to such projects, particularly in civil and transportation engineering roles.
In contrast, jobs in sales might not be primarily associated with these agencies, as they relate more to the private sector and commercial activities. Similarly, education as a primary employment pathway is more commonly found in schools and academic institutions, although transportation agencies might employ educators for outreach programs and training purposes.
