Synonyms/Homonyms in multiple choice problem

Hello,

I’m having the problem that when I ask for readings in my course, and 2 items have the same correct answer, only the expected one counts as correct, while the other, equally valid one, would be counted as correct.

I ask for example for ほう and have 報 and 放 as option. The system expects 報, so 放 is “incorrect”.
This is obviously not a problem when writing, but the course is made as quick on the go thing, so no text input.

How do I make the third row “always visible”? That would work, too. My course looks like this:

価,|か|value
価,|value|か
値,|ね|value
値,|value|ね
副,|ふく|vice
副,|vice|ふく

The first is being presented, the second the expected answer, the third pops up after I chose an answer. If it was always visible, this won’t be a problem.

Thanks in advance!
