If the answer is "yes", it means that the paper has quoted previous works, which is in line with academic norms. However, if the answer is "no", it means that the paper has not quoted the works of predecessors, which violates academic norms. So it is not allowed.

The meaning of whether the paper is cited refers to whether the paper has cited the references of previous works in the test, and usually all the references to be cited will be listed at the end of the article.
