How to answer if I don't know anything about the topic Example question: How will robots change restaurants in the future? Reason: To be honest, I don't know much about this topic at all, but I guess robots will make the service faster in restaurants. Example: For instance, I've seen online that some places are already using robots to deliver food to tables, and people seem to love it. Extra information: In the future, robots might even help with cleaning tables or taking orders. And, although this might feel strange at first, this is probably what is going to happen in my opinion.
