2025 civics test · Question 15 · Principles of American Government

There are three branches of government. Why?

Any one of these answers is accepted

  • So one part does not become too powerful
  • Checks and balances
  • Separation of powers

What this means

Power is split among three branches so that no one part of government becomes too powerful. Each branch can limit the other two. This system is called checks and balances, or separation of powers.

Some examples of how it works in practice:

  • Congress passes a bill, but the president can veto it.
  • Congress can override that veto with a two-thirds vote.
  • The courts can rule that a law violates the Constitution.
  • The president appoints judges, but the Senate must approve them.

Any of “checks and balances,” “separation of powers,” or “so one part does not become too powerful” is an accepted answer.

Why this is on the test

Checks and balances explain why the president cannot simply pass a law and why Congress cannot decide a court case, a pattern that appears in many other test questions.
