Answer:
You must give credit to the author or primary source because the passage and the original thinking or idea were not created by you but rather by someone else. You must do this whether you directly quoted from it, paraphrased it, or summarized it. According to our constitution, you will be sued for plagiarism if you don't. Keep in mind that plagiarism is a serious offense that might result in you spending time in jail or paying a hefty fine.
