Code

function _captcha_get_description($lang_code = NULL) {
  $default = t('This question is for testing whether you are a human visitor and to prevent automated spam submissions.');
  if (module_exists('locale')) {
    if ($lang_code == NULL) {
      global $locale;
      $lang_code = $locale;
    }
    $description = variable_get("captcha_description_{$lang_code}", $default);
  }
  else {
    $description = variable_get('captcha_description', $default);
  }
  return filter_xss_admin($description);
