    Suppose you have a question like this in your dropdown menu.

    Q - How many colors does the US flag has?

    Now, from what I understand you want your choice from the drop down menu to appear instantly..

    Well, here is a simple select form. 

    <form method="post">
<select id="opt" name="opt">
    <option value="four">four</option>
    <option value="five">five</option>
     <option value="two">two</option>
     <option value="million">million</option>
</select>​

    And, the JS code: 

    $(document).ready(function() {
    $("#opt").change(function() {
        alert($(this).val());
    });
});​

    Now, click her a DEMO with jsFiddle to show you, how it works.
    You can copy/paste the codes and include them in your site, this is a simple code, but you if you small knowledge of Javascript you can manipulate the data the way you need it to appear. .
