Challenge question explanations

Question

I think it would be helpful if challenge questions either had a link internally on Sololearn to references for the tested concept or alternatively, to teaching about a tested concept. Is this something that's already there and I just don't see or is it something that could be implemented for better learning when you review the results of a challenge? I'm not saying that force challenge authors to do this, but maybe give them the option?
