input: Write a function to create an AI-based chatbot in Python that can answer simple queries about a product or service. The chatbot should have a predefined set of answers for specific questions. If the question is not in the predefined answers, it should generate a random response indicating uncertainty. The function should take a question as input and return a response as output.
  
  def generate_response(question, 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.'}, unknown_responses=['I am not sure I understand.', 'Can you give me more information?', 'Can I help you with something else?']):
      if question in answers:
          return answers[question]
      else:
          return random.choice(unknown_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('Who owns XYZ?') in ['I am not sure I understand.', 'Can you give me more information?', 'Can I help you with something else?']
output: import random
