Plagiarism is defined as "using information from sources in your writing without acknowledging those sources." This means taking someone else's ideas, words, or work and presenting them as your own without proper attribution.
The other options listed do not constitute plagiarism:
- Writing a summary of an article or story can be done without plagiarism if you rephrase the content and provide proper credit.
- Editing a peer's essay is not plagiarism; it is typically a collaborative process.
- Citing your sources correctly is the practice that prevents plagiarism by giving credit to the original authors.
