Final answer:
The disadvantage of checks and balances is that it can lead to gridlock, but the benefit is it prevents any one branch from becoming too powerful.
Step-by-step explanation:
The potential disadvantage of checks and balances in a democratic system is that it can sometimes lead to gridlock and slow down the decision-making process. This can be especially problematic when urgent action is needed. However, one major benefit of checks and balances is that it prevents any one branch of government from becoming too powerful and helps maintain a system of accountability. It ensures that decisions are carefully considered and prevents any branch from abusing its power.
