> how to display the answer of "unanswerable"?

Dear Organizers:
When I cann't answer a question of a recipe, what should I put in the 'value' of the submission json file?
I try to put a empty string :"" in the answer value. But it seems that it's not explained as "unanswerable"?
So, what should I submit to mean a "unanswerable" answer?
Thanks!

In the response json please post null instead of "" or "N/A".
```
"18-3": null,
```

Please note that "null" (quoted) will be incorrect.
