Restrict Response
This check box will provide the option to limit the Response Length and also perform Response Validation. You can control the length of the text being entered into the text field, such as a minimum length or the maximum length. As for the validation, you can control what type of input is allowed, such as numbers, strings, email addresses, etc.
Automatic Scoring
When checked, you can set a text field validation that will automatically score certain points when the response entered by a survey respondent matches the validation you have defined. This option will only appear if you have enabled response scoring for the survey in your survey options.
