// $objects is the array with all those objects
foreach($objects as $object)
{
  echo $object->cue->language; // language

  foreach($object->responses as $response)
  {
    // if there are no quizzes, we skip the part below
    // we skip it because $object->quizzes will produce a warning or a notice
    // if "quizzes" is not a present in the $object
    if(!isset($object->quizzes))
    {
      continue;
    }

    // quizess
    foreach($response->quizzes as $quiz)
    {
      echo $quiz->question; // question
      echo $quiz->answer; // answer
    }
  }
