JQuery + .show()

JQuery + .show()

This is a simple example of radio buttons using JQuery
JSFiddle
So what I want is to be able to slowly display the radio buttons something
like this:
JSFiddle - show()
but instead of having .html here I want to slowly fade it in
$("#answer").html(answers);
something like
$("#answer").show('slow');
but i can't quite work it out. Can someone please advise?
