Name the modern day country that these crops have first been found in. Because of the lack of consensus among several of these, some of the answers might not be 100% accurate.
Considering how impossible this quiz is, it might be a good idea to reduce the time limit and do away with the yellow box. That would make it more fun for everyone aside from agricultural history majors.
I dunno I found it interesting, it's just very difficult for most of these. Without the box then you could at least get some from guessing without having to type in the same countries over and over again.
