Questions: QUESTION 28 One way that Congress has used its spending authority over the years is to A. force witnesses to appear before congressional committees. B. allow the president to use the line-item veto in specific situations. C. eliminate the president's authority to impound funds. D. require local governments to follow specific regulations when receiving funding.

The answer is D. require local governments to follow specific regulations when receiving funding.

This option is incorrect because Congress uses its subpoena power, not its spending authority, to compel witnesses to appear before congressional committees.

This option is incorrect because the line-item veto is a power that would allow the president to veto specific parts of a bill without rejecting the entire bill. Congress does not have the authority to grant this power through its spending authority; it would require a constitutional amendment or specific legislation.

This option is incorrect because the elimination of the president's authority to impound funds was achieved through the Congressional Budget and Impoundment Control Act of 1974, not through Congress's spending authority.

This option is correct because Congress often uses its spending authority to attach conditions to the funds it provides to state and local governments. This is a common practice to ensure that federal funds are used in accordance with federal policies and regulations. For example, Congress may require local governments to comply with certain environmental standards or educational requirements as a condition for receiving federal grants.
