For one particular question, most of the freeform answers will be one of a few possibilities, but there will be some outliers. Can I suggest these possibilities without limiting it?
For CROWD Users
Yes! Add a Special Instructions with all common answers. Workers will see your suggestions that should help them in their data entry.
Alternatively, if you are only interested in the few possibilities and not the outliers, you can define the field as a Multiple Choice, Select-One. The options can be the primary possibilities, with a final option for "Other."
