What issue could be posed by allowing revisions after the first answers?

Allowing revisions after candidates submit their initial answers can lead to a potential loss of originality in grading because it may cause candidates to modify their responses based on subsequent reflections or influences. This could result in an answer that no longer reflects the candidate's original thought process or understanding of the material. As candidates revise, they might inadvertently or intentionally align their answers more closely with course materials or peer responses, thus diluting the originality of their work and making it difficult for evaluators to assess their true grasp of the subject matter.

In this context, maintaining authentic responses is crucial for accurate assessment of an individual's knowledge and skills. The grading process aims to evaluate each candidate’s unique perspective and analytical abilities; frequent revisions could compromise this goal.

Other possible outcomes of allowing revisions—such as increased clarity, encouragement of thoroughness, and enhanced confidence—could occur, but they do not directly address the issue of originality in grading, which is why the selected answer is particularly pertinent.
