Final answer:
The increase in federal power over state governments necessitated accurate financial management information at the highest levels. The Unfunded Mandates Reform Act was implemented to address the challenges posed by federal mandates.
Step-by-step explanation:
The increase in federal power over subnational governments led to the need for accurate and timely financial management information at the highest levels of government. This need was further escalated by growing financial resources, which allowed the federal government to dictate the terms and conditions for state governments to qualify for financial assistance. To address these challenges, the Unfunded Mandates Reform Act was passed in 1995 to provide transparency and reduce the federal government's use of mandates.
