Invention is to piracy as writing is to what?

The analogy compares two pairs of concepts that represent a relationship where one is a form of original creation and the other represents unauthorized use or imitation of that creation. In the first pair, invention is an original act of creation, while piracy refers to the unauthorized use or reproduction of someone else's invention.

In the second pair, writing serves as the original act of creation, similar to invention. Plagiarism, in this context, accurately represents the unauthorized appropriation of someone else's written work. It involves taking someone else's ideas or phrasing and presenting them as one's own without appropriate acknowledgment. Thus, just as piracy is an illegitimate appropriation of invented ideas, plagiarism is the analogous illegitimate appropriation in the context of writing. This makes the relationship clear and logically consistent with the first pair, identifying plagiarism as the correct answer.
