input: Write a function to implement an AI-based chatbot that can answer simple queries about a product or service. The function should return a predefined response if the question is in the answers dictionary, otherwise it should return a randomly chosen default response. If the question received is "Goodbye", the function should terminate the conversation.
  
  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.'
  }
  
  default_responses = ['I am not sure I understand.', 'Can you give me more information?', 'Can I help you with something else?']
  
  def generate_response(question):
      if question in answers:
          return answers[question]
      elif question == 'Goodbye':
          return 'Goodbye'
      else:
          return random.choice(default_responses)
  
  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 the weather today?') == 'I am not sure I understand.'
  assert generate_response('Goodbye') == 'Goodbye'
  assert generate_response('Can I get a discount?') == 'Can I help you with something else?'
output: def generate_response(question):
      if question in answers:
          return answers[question]
      elif question == 'Goodbye':
          return 'Goodbye'
      else:
