Which example is considered plagiarism?

Plagiarism occurs when someone presents another person's ideas, words, or creative expressions as their own without proper attribution. The scenario involving the literary analysis exemplifies this perfectly. By paraphrasing an author's work while failing to give credit, the individual is essentially claiming those ideas and expressions as original, which misrepresents the source's contribution to the discourse.

This act disregards the foundational academic principle of honesty and integrity in scholarship. Proper citation is crucial because it acknowledges the original creator's intellectual property and allows readers to trace back the ideas, further enhancing academic dialogue. In contrast, the other options—note-taking from a lecture, summarizing a book in one's own words, or sharing thoughts on readings—do not involve misrepresentation of someone else's work since they either consist of personal reflections or properly attributed information.
