Enables your site to capture votes on different topics in the form of multiple choice questions.

Code

  // passes them by reference.  So when the objects are cached it can result in
  // the wrong output being displayed on subsequent calls.  The cloning and
  // unsetting of $node->content prevents the block output from being the same
  // as the node output.
  $node = clone $node;

  // No 'read more' link.
