Hello how may I help you? How many planets are there in the solar system I'm sorry, I can't find any information on that at the moment. Can you tell me how many days there are in a week? There are seven days in a week. Then how many days are in a year? I'm sorry, I can't get any information from the internet. well how many weeks are in a year? I'm sorry I can't answer that either. Ok. Thanks for your help. You're welcome.
