Question

compare the student text with the source.
source: carolyn cinami decristofano, a black hole is not a hole, page 5. published by charlesbridge, 2012:
nothing can out-tug a black hole. no army of tow trucks, no convoy of supersized earth haulers, no fleet of giant rocket engines.
student text:
the pull of a black hole is so strong that nothing can pull stronger, not even a fleet of giant rocket engines (decristofano 5).
is the student text plagiarized?
no, it is not plagiarized.
yes, because it fails to use quotation marks.
yes, because it fails to use quotation marks and fails to cite the source.

Explanation:

The student rephrased the core claim of the source text in their own words, only used a short, common-phrase detail from the source ("fleet of giant rocket engines") which is integrated into their original sentence, and properly cited the source author and page number. No direct, unquoted full phrases from the source are used beyond a minor illustrative detail, so this is not plagiarism.

Answer:

No, it is not plagiarized.
