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 use a predefined dictionary of questions and answers, and if the question is not recognized, it should provide a random response. If the user's query persists, the chatbot should continue to prompt the user for more questions until the user says "Goodbye". If the given dictionary is empty, the chatbot should provide a random response for any query.
  
  def generate_response(question, answers):
      if not answers:
          return random.choice(['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(['I am not sure I understand.', 'Can you give me more information?', 'Can I help you with something else?'])
  
  assert generate_response('What is XYZ?', {'What is XYZ?': 'XYZ is a company that provides XYZ services.'})=='XYZ is a company that provides XYZ services.'
  assert generate_response('Where is ABC located?', {'What is XYZ?': 'XYZ is a company that provides XYZ services.'}) in ['I am not sure I understand.', 'Can you give me more information?', 'Can I help you with something else?']
  assert generate_response('Where is ABC located?', {}) in ['I am not sure I understand.', 'Can you give me more information?', 'Can I help you with something else?']
output: import random
