I've gone ahead and updated the Captcha recipe to make this
slightly simpler.  The new local customization is:

  $CaptchasList = array(
    'What day comes after Monday?' => 'Tuesday',
    'What color is a green apple?' => 'green',
    'What is larger, an elephant or an ant?' => 'elephant',
    'What shape is a circle?  It is ro...' => 'round',

  $CaptchaChallenge = array_rand($CaptchasList);
  $CaptchaValue = $CaptchasList[$CaptchaChallenge];


Now all one has to do is set $CaptchaChallenge to whatever
should be displayed as part of the {$Captcha} page variable 
(in the form), and $CaptchaValue to the matching response.  

The default is still to create an image from $CaptchaValue
if possible, and $CaptchaValue still defaults to a random 
number between 1000 and 9999.

Hope this helps!
