Why does the Constitution and the Declaration of Independence are called Living documents?

I need an answer why to write my government report.

The Constitution is a living document because we can amend and change it. Also, the Supreme Court continuously interprets the Constitution in light of modern problems.

Certainly! You can try using popular online newspaper websites such as The New York Times (www.nytimes.com), The Washington Post (www.washingtonpost.com), or The Guardian (www.theguardian.com). These websites often provide a wide range of articles on various topics. Additionally, you can also use search engines like Google News (news.google.com) to find specific newspaper articles by entering relevant keywords.
