Final answer:
Ornette acts as a conduit for homeless people by linking them with essential services and resources in the community.
Step-by-step explanation:
Ornette, the social worker described in the question, best fits the role of a conduit for homeless people in his community. As a social worker, his role involves connecting people who are homeless with the services designed to help them, such as housing, healthcare, food assistance, and other resources. He is not acting as a monitor, gatekeeper, or judge; rather, he is facilitating the flow of information and resources between the services and the individuals in need.
