input: Write a function to create an AI-based chatbot that can answer simple queries about a product or service. The bot should use a predefined dictionary of answers for common questions and generate random responses for unknown questions. If the user says 'Goodbye', the chatbot should end the conversation.
  
  
  def generate_response(question, answers):
      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?'])
  
  def start_conversation(answers):
      question = input('Welcome to XYZ. How can I help you? ')
      response = generate_response(question, answers)
      
      while response != 'Goodbye':
          print(response)
          question = input('Is there anything else I can help you with? ')
          response = generate_response(question, answers)
      
      print('Goodbye!')
  
  # Example dictionary of answers
  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.'
  }
  
  # Example usage
  start_conversation(answers)
  
  
  **Test Case 1:**
  assert generate_response('What is XYZ?', answers) == 'XYZ is a company that provides XYZ services.'
  
  **Test Case 2:**
  assert generate_response('What does XYZ do?', answers) == 'XYZ helps customers find solutions to their problems.'
  
  **Test Case 3:**
  assert generate_response('Where is XYZ located?', answers) == 'XYZ is located in ABC city.'
  
  **Test Case 4:**
  assert generate_response('What are the benefits of using XYZ?', answers) == 'XYZ provides a quick and easy way to find solutions to your problems.'
  
  **Test Case 5:**
  unknown_question = 'What is the sky color?'
  possible_responses = ['I am not sure I understand.', 'Can you give me more information?', 'Can I help you with something else?']
  assert generate_response(unknown_question, answers) in possible_responses
