You can have answers automatically randomized for any closed-ended question types (dropdown, radio buttons, checkboxes, etc). You can also let people who choose "other" get prompted to make a text field response. You can even create anchors or randomization groups. You get to all this from Screeners >> Questions and clicking on any closed-ended question. Please note these options will not appear for open-ended questions like paragraph.
If you want to create groups click "Use Groups Randomization".
