input: Write a function that implements an AI-based chatbot in Python to answer simple queries about a product or service. The chatbot should store predefined answers to common questions and generate random responses for unknown queries. The chatbot should continue the conversation until the user says "Goodbye".
  
  ### Function:
  
  import random
  
  # The answers to the queries
  answers = {
      'What is XYZ?': 'XYZ is a company that provides XYZ services.',
      'What does XYZ do?': 'XYZ helps customers find solutions to their problems.',
      'Where is XYZ located?': 'XYZ is located in ABC city.',
      'What are the benefits of using XYZ?': 'XYZ provides a quick and easy way to find solutions to your problems.'
  }
  
  # Generate a response
  def generate_response(question):
      if question in answers:
          return answers[question]
      else:
          return random.choice(['I am not sure I understand.', 'Can you give me more information?', 'Can I help you with something else?'])
  
  # Start the conversation
  question = input('Welcome to XYZ. How can I help you? ')
  response = generate_response(question)
  
  while response != 'Goodbye':
      print(response)
      question = input('Is there anything else I can help you with? ')
      response = generate_response(question)
  
  print('Goodbye!')
  
  
  ### Assertions:
  
  assert generate_response('What is XYZ?') == 'XYZ is a company that provides XYZ services.'
  assert generate_response('Where is XYZ located?') == 'XYZ is located in ABC city.'
  assert generate_response('What is your name?') in ['I am not sure I understand.', 'Can you give me more information?', 'Can I help you with something else?']
  assert generate_response('Goodbye') == 'Goodbye'
  
output: def generate_response(question):
      if question in answers:
          return answers[question]
      elif question == 'Goodbye':
          return 'Goodbye'
      else:
          return random.choice(['I am not sure I understand.', 'Can you give me more information?', 'Can I help you with something else?'])
