input: Write a function to create an AI-based chatbot in Python that can answer simple queries about a product or service. The function should take a question as input and return an appropriate response from a predefined set of answers. If the question is not in the predefined set, the function should return a randomly selected fallback response.
  assert generate_response('What is XYZ?')=='XYZ is a company that provides XYZ services.'
  assert generate_response('What does XYZ do?')=='XYZ helps customers find solutions to their problems.'
  assert generate_response('Where is XYZ located?')=='XYZ is located in ABC city.'
  assert generate_response('What are the benefits of using XYZ?')=='XYZ provides a quick and easy way to find solutions to your problems.'
  assert generate_response('How does XYZ work?') in ['I am not sure I understand.', 'Can you give me more information?', 'Can I help you with something else?']
output: def generate_response(question):
      responses = {
          '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.',
