Answer:
The given statement represents the weakness of a federal system.
Explanation:
A federal system divides power between a central government and regional or state governments. In this case, the issue arises because the bridge maintenance projects are stalled due to the uncertainty of receiving federal funds from Congress. This uncertainty highlights the challenge of coordinating and obtaining support from the central government in a federal system. If the government had a stronger or more centralized decision-making process, such as in a unitary system, there might be a greater guarantee of assistance for such projects. Therefore, the correct answer is E. Weakness of a federal system.
