Got stuck in that one too because I mistranslated vegetables.
In my mind, they were all vegetables, since they are no animals or minerals. As it would be in Portuguese.
Edit: thinking about it, he wanted to make a joke about Mr Potato, but ended up creating a captcha for non-English native speakers. He could try selling that idea to ICE lol
Corn was the trick for me. I classify it as a grain, but it listed it as a vegetable according to the captcha.
When I looked it up, I found this.
> Botanically speaking, corn is a fruit, and the kernel itself is classified as a grain. However, in culinary terms, whole corn, such as corn on the cob, is typically treated as a vegetable.
