For example: How useful do you find SurveyMonkey's Help Center Topics
and the email support center?
Double-barreled questions ask two questions at once. In a survey
multiple ideas presented at the same time inhibits a useful response.
The respondent may find SurveyMonkey's Help Center very helpful and
the email support center not as helpful, but the question doesn’t
provide them any opportunity to distinguish their opinions on either.
