They may want to know what you're growing. I give vague answers, because my crops change. I am a market gardener, if I understand how my level is defined, etc. (Just had to participate in the USDA Agricultural Census, I'm sure people like chickenman know what that means.) If cultivation is the issue, then peppers and solaneceous veggies would be my own response, but then I would launch into a little schpiel about my failure with cole crops and successes with carrots and some root veggies, and would ask that the test allow me the flexibility to figure out what crops I'll be growing, since I experiment with so many.
Gotta learn the gift of babble.
