Clearer UI with correct answers

[alexeygrigorev]

Currently when no answer is submitted, it shows as green, which is confusing for students

We need to make it clearer why it's 4 not 5

More context. Imagine the following scenario

• A student submits the homework
• They forget to answer one of the questions
• We score the homework, so the form is closed

Now we show the correct results - and the question that wasn't submitted by the student shows a great line with the correct answer.

This behavior is confusing for the student because they think they actually selected this answer - and they wonder why they miss some of the points.

Right now we can see that no answer was selected because there is no dot in the selection. But it's hard to notice

What we should do instead is somehow indicate that no answer was given by the student. Perhaps by saying "no option was submitted" or something like that?

We should solve it

Text from screenshots: That's why it's green. Look at the green lines. There are no dots. You somehow didn't select any answer there

Potential solution: just say that "no answer was submitted"

Also another related issue: here we have score one because first question accepts any. Instead the semantics should be anything that's not empty. Let's add tests for that and fix it
