Answer: This is a "PARAPHRASING PLAGIARISM"
Explanation: Paraphrasing plagiarism is when we paraphrase words in someones literature work, to make it look like it our own words without acknowledging the original owners of that work.
The student has committed a paraphrasing plagiarism, by paraphrasing the main source literature work, to make it look like it's own. Without acknowledging the main source. The student has projected his point in the same way with the original source.
Because knowledge can never be the same in two different person, this is plagiarism, as the student has not acknowledged the main source, where the knowledge of it's work is gotten from.
