Questionnaire - efficient way to build and Continue button issue

Hi. I have a set of Questionnaire consisting of a set of 30 questions with Likert scale (1 - 5)

What is the most efficient way to build such a questionnaire without having to retype the 5 Answer Text fields for each question?

Also, when I preview the Questionnaire, the Continue button on the right corner is hardly visible (even when moused over) unlike the Example you have for this Activity type. How do I go about setting the colors to be more visible?

Thanks
