Answer 1

function find(title, poll, parent){
    
    parent = parent || poll;
    
    if (poll.title === title)
        return parent;
    
    var result;
    
    poll.reply && poll.reply.some(function(reply){
        return reply.poll && (result = find(title, reply.poll, poll)) || false;
    });
        
    return result;
}

find('Вопрос 2', mass.poll);
