Further modifications for Section 508 compatibility. The presentation method for array type questions does not easily lend itself to the requirement of <label> statements - I have put labels in, however this does not really meet the spirit of Section 508 - so I've also added "title" elements in the radio buttons where needed to clarify what the radio button represents.
