Why Are There Three Branches of Government? Civics Question 15

The answer is so one part does not become too powerful.

Question 15 asks why there are three branches of government. Three answers are accepted: “so one part does not become too powerful,” “checks and balances,” and “separation of powers.” Any one of them counts. The first is the plain-English version and the other two are the textbook names for it.

Why the Founders Split Power Up

The people who wrote the Constitution had just fought a war against a king. They did not want to build a new government that could turn into the thing they escaped from.

Their fix was to cut the power into three pieces and hand each piece to a different group. Congress writes the laws. The president carries them out. The courts decide what they mean. No single office holds all three jobs.

Then they wired the three together so each one can slow the others down. Congress passes a bill and the president can veto it. Congress can override that veto. The courts can strike down a law that breaks the Constitution. That wiring is what “checks and balances” names.

Why the Officer Asks This

Questions 15 through 20 travel together. This one asks why the branches exist, the next asks you to name them, and the ones after that go through what each branch does.

This one states the reason behind the rest of the group. Power is divided on purpose, and the branches are the shape that division takes.

How to Remember the Three Accepted Answers

All three answers describe the same design, so choose by how they sound in your mouth.

“Separation of powers” describes the split itself: three branches, three jobs. “Checks and balances” describes what happens after the split: each branch can check the others. “So one part does not become too powerful” is why anyone bothered.

If the two names slip away from you, use the long plain answer. You can rebuild it from the idea itself: three branches exist so no single branch holds all the power.

What to Say on Test Day

Say “so one part does not become too powerful.” Or say “checks and balances,” or “separation of powers.” One of the three, then stop.

Do not deliver all three in a row to be safe. The officer marks the first correct answer, and the extra words only give you more chances to slip.
