It’s better to show the corrected answer as a whole first, and then provide the breakdown of the corrections as a subsection — for example, under a “Corrections in Detail” button. Essentially, it separates the content so readers can first read through a clean, corrected paragraph. Then, if they want to see how it differs from their original answer, they can click “Show More” or something similar. Alternatively, it could be displayed in two columns. I feel the current format looks a bit visually overwhelming.
