Question

source: carolyn williams, \a natural label on food means next to nothing. heres why.\ published on cookinglight.com, 2016:
heres the situation:
atural\ on food doesnt mean much. in fact,
atural\ really guarantees little to nothing about a foods quality, ingredients, or how it was grown or raised—meaning the food could (or could not) contain artificial ingredients, gmos, chemicals, hormones, and antibiotics.
student text:
williams asserts that just because a food is labeled
atural,\ that doesnt necessarily mean that it is free of antibiotics, chemicals, hormones, gmos, or artificial ingredients.
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:

Plagiarism involves using someone else's work without proper citation or mispresenting it. The student text paraphrases Williams' idea (stating the same concept about "natural" food labels not guaranteeing absence of certain ingredients) but does not use direct quotes (so no need for quotation marks here as it's a paraphrase) and also, importantly, fails to cite the source (Williams, 2016) to attribute the idea. The first option is wrong as attribution is missing. The second is wrong because quotation marks are for direct quotes, and this is a paraphrase— the main issue is lack of citation. The third option correctly identifies that the student failed to cite the source (and the quotation mark claim is a red herring here, but the key is no citation; however, among the options, this one includes the citation failure which is a core plagiarism - related issue when using others' ideas).

Answer:

Yes, because it fails to use quotation marks and fails to cite the source.
