Answer:
Plagiarism
Explanation:
In research, the term plagiarism refers to taking some other person's work (or ideas) and writing them as if they were one's own ideas. In other words, it's taking the ideas of someone else and making them look as if they were one's own.
In this example, Jose quotes a well-known anthropologist's opinion but doesn't mention the source of his idea. We can see that he is taking the ideas from someone else and he is making them look as if they were his own (since he's not quoting the original author). Therefore, Jose is involved in the act of plagiarism.
