when should an essay writer provide a source?\na. when the writer thinks up a unique idea\nb. when an idea…

Brief Explanations:

When an idea is being directly quoted, it means that the exact words of another source are being used. In academic writing, especially in essays, it is crucial to provide a source (such as an in - text citation and a reference in the bibliography) when using someone else's exact words. This is to give credit to the original author and to avoid plagiarism.

• Option A: A unique idea thought up by the writer is original work and does not require a source citation (unless it is building on very well - known prior research in a field, but generally, new ideas from the writer themselves are their own contribution).
• Option B: A conclusion drawn by the writer is part of their own analysis and synthesis of information (even if based on sources, the conclusion - drawing process is the writer's own work and not a direct borrowing that requires a source in the sense of a direct quote).
• Option C: A personal opinion is the writer's own view. While it may be influenced by reading, it is not a direct borrowing of someone else's words or ideas in the way that a direct quote is.

Answer:

D. When an idea is being directly quoted
