Final answer:
Many scholars argue that categorical grants-in-aid limit recipients' discretion in the use of funds and subject them to strict administrative criteria in order to advance national objectives.
Step-by-step explanation:
Many scholars argue that categorical grants-in-aid limit recipients' discretion in the use of funds and subject them to strict administrative criteria. These grants are formulated to advance national objectives and require recipients to meet specific requirements and guidelines in order to receive funding. Categorical grants also often require a commitment of matching funds from the recipients. While block grants provide more flexibility in how the funds can be used, many scholars argue that categorical grants are preferred by the national government because they allow for greater control over the use of funds and ensure that they are used to achieve specific policy objectives.
