Final answer:
Broad grants with few strings attached designed for specific activities like education and health services are known as block grants.
Step-by-step explanation:
Broad grants to states for specified activities such as education and health services, with few strings attached, are called block grants. Block grants offer more flexibility compared to categorical grants, allowing state and local governments more latitude in how to use these funds. They are less prescriptive than categorical grants, which have strict administrative criteria and often require matching funds. For instance, block grants support wide-ranging projects such as improving workforce skills or enhancing transportation infrastructure, while adapting to local priorities and needs.
