input: Write a function that generates responses to simple queries about a product or service using a predefined set of answers. If the query is not found in the predefined set, the function should return a random fallback response. The function should continuously ask for new queries until the user inputs 'Goodbye'.
  
  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.'
      }
      if question in answers:
          return answers[question]
      else:
          fallback_responses = ['I am not sure I understand.', 'Can you give me more information?', 'Can I help you with something else?']
          return random.choice(fallback_responses)

  assert generate_response('Where is XYZ located?')=='XYZ is located in ABC city.'
  assert 'help you with something else' in generate_response('Random query')
