Empty White Space in Knowledge Check questions

Why is there so much white space after the last choice in a Knowledge Check before the feedback? It makes the whole question quite long (in my case, it takes up the whole screen) and thus prevents the user from seeing the next block of content without having to scroll -- which is relevant here, because right now the only option after submitting even a correct answer is, Take Again. So the user may not have an obvious visual cue to proceed. (On a separate chain, I have added my voice to those requesting the feature to hide Take Again and prompt the user to move on if desired.)
