When adding new field types (questions) to a survey, the field type is automatically set to the "Radio-Button-List", as the default. But, certainly this isn't the only way you want to ask questions, so you can modify the field type for each question that should be changed.
Field types are listed in SAM as follows:
How to change survey response suggestions (field types):
1. Open the survey
2. Click on the survey question you'd like to change
3. Under "field type" click the entered response (such as radio-button, text, etc.) (or click "Advanced Options from the side bar, then "Edit Field Type.")
4. Select the correct field type and click Save
5. After the changes save, click "Go Back" on the sidebar, then scroll down to the bottom and click the Survey title to get back to main survey form.
Also note: From the sidebar, you can reorder fields, change which fields are required, add sections, and add or remove fields
