Answer:
False.
Step-by-step explanation:
Using someone else's ideas without making the proper citation is considered plagiarism. Every time a person uses an idea from another author, a citation is needed to avoid plagiarism given that you are "borrowing" that person's ideas and credit must be given to the original creator of that idea. This does not mean that we can't use another author's ideas. One can signal that a particular idea does not belong to them but still use them in a text.
