I do that 

foreach ($questions as $question) {

    $questionInstance = question_bank::load_question($question->id);
    $quba = question_engine::make_questions_usage_by_activity('qtype_multichoice', $contextId);
    $quba->set_preferred_behaviour('adaptive');
    $slot = $quba->add_question($questionInstance, $questionInstance->defaultmark);
    $quba->start_question($slot);

    $response = $questionInstance->get_correct_response();
    $response['-submit'] = 1;
    $quba->process_action($slot, $response);

    $options = new question_display_options();
    $options->readonly = true;
    $options->flags = question_display_options::HIDDEN;
    $options->suppressruntestslink = true;


    echo $quba->render_question($slot, $options);
    echo "<hr/>";
}
