2. In order to keep citizens from being denied

certain rights, Congress took this action:

(a) repealed an amendment (b) passed voter

protection laws (c) changed election day

(d) overrode the president's veto.

Passed voter protection laws.

Explanation:

We can eliminate three answers here.

Answer A) Only one amendment in the United States history has ever been repealed. It was the 18th amendment which enacted prohibition. This amendment was repealed by the 21st amendment. So that answer can be eliminated because it was not repealed to protect citizens rights as outlined in the Constitution.

Answer C) Election day has never been changed and also, if you think about it, how in any way shape or form would that prevent citizens from being denied rights?

Answer D) Congress does have the power to override a presidential veto if both the House and Senate vote to override with a two thirds majority. This is a way to protect citizens rights, in a sense, but we can eliminate this answer because the power to override a presidential veto is purely just a power given to Congress as outlined in the Constitution.

Therefore, we're left with option B. And yes, this is the correct answer. Congress has passed many laws that protect voting rights. A huge example of this is the Voting Rights act of 1965 which all but eliminated discrimination in the voting process. That's how we know this is the correct answer. The right to vote is a right outlined in the U. S. Constitution. Therefore, passing voter protection laws is a way in which citizens are kept from being denied certain rights.
