For Select and Multi Select fields, if the Select Values (i.e., answer choices) are too long, the text will end up getting cut off when displayed to the end user.
To address this, you can either try to shorten your Select Value text or you can change the field type to use a Radio or Checkbox field instead.
Radio and Checkbox fields will both display all answer choices in a list below the question, and all answers will display their full text. Radio fields are like Select fields where only one option can be selected, whereas Checkbox fields are like Multi Select fields where more than one option can be chosen.
Check out our Changing Field Types help article for instructions on how to change a Select or Multi Select field to a Radio or Checkbox field, respectively.
