This paragarpah is where you explain the purpose of the questions in this particular section.On this page we see questions of type "text", "checkbox" and "radio". You'll see a "Next" button at the bottom of this section which has an auto-generated javascript action to hide this section and display the next. label-for attributes are used so you can click an answer's text to select its element.
In this section we have types "select" and "textarea", as this is the last section of two we have a "Previous" button to return to the first page and a "Finish" button which is the final submit action for the form. Unique values are generated for id's of each radio and checkbox type so that the label-for actions don't collide where two questions may share an answer. Clicking a "Next" or "Previous" button simply hides and show's div's so the values you enter on a section arent lost as you navigate about.
