Is the student's text plagiarized?

No, the student's text is not plagiarized. While it includes some similar language and ideas from the source, it does not directly copy any sentences or passages. The student has used their own words to paraphrase and summarize the information from the source. However, proper citation should still be provided to give credit to the original author.

To determine if the student's text is plagiarized, we need to compare it with the source text. Let's compare the two:

Student text: As Donahue writes, every year the demand for pennies varies because so many of them fall through the proverbial cracks.

Upon comparison, we can see that the student's text closely resembles the source text but includes quotation marks and credits the original author, Michelle Z. Donahue. This indicates that the student has used the source as a reference rather than attempting to pass it off as their original work. Therefore, the student's text is not considered plagiarized.
