Question

Quizplus · Accepted Answer

Sometimes an article may have influenced what was written but specific ideas from it were not directly used or cited. In such cases, it may still be included in the bibliography as a source of inspiration or background material. Options A and B describe situations where the article is directly used, even if only in a limited way, so they are not correct. Option D suggests that the article is indirectly cited through other sources, which does not fit the description of an article that is not directly cited.
