Explanation:
Plagiarism, in general, is a term for using other people's ideas as your own, without citing the source. The rule is that, if we want to include quotes from other works in our own work, we need to both include the quotation marks and acknowledge the source.
Depending on the citation style that we opt for, we can acknowledge the source either in the text itself, in a footnote or in a list of references. However, regardless of the style, we must always include the quotation marks when we repeat the exact words of an author (if we paraphrase them, we do not put the quotation marks).
<u> In the case above, the quotation marks are not used, which is why we consider it a plagiarism.</u>
