input: Write a function that creates an AI-based chatbot in Python that can answer simple queries about a product or service. The function should include a dictionary of predefined answers and a mechanism to generate a response based on user input. The chatbot should continue to respond to the user until they say 'Goodbye'. The function should be called generate_response and should take a single argument, question, which is the user's query. If the query is found in the predefined answers, the chatbot should return the corresponding answer. If the query is not recognized, the chatbot should return a randomly chosen response indicating uncertainty or a request for more information. The function should be tested with the following assertions:
  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('I am not sure I understand.') in ['I am not sure I understand.', 'Can you give me more information?', 'Can I help you with something else?']
  assert generate_response('Hello') 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.',
          'What are the benefits of using XYZ?': 'XYZ provides a quick and easy way to find solutions to your problems.'
      }
      uncertain_responses = ['I am not sure I understand.', 'Can you give me more information?', 'Can I help you with something else?']
      
      return responses.get(question, uncertain_responses[0])
