Alienbot cubed_intent

hi I finished the project but got issues when trying to get cubed_intent

# importing regex and random libraries
import re
import random

class AlienBot:
  # potential negative responses
  negative_responses = ("no", "nope", "nah", "naw", "not a chance", "sorry")

        "What do you consume for sustenance? ",
        "Is there intelligent life on this planet? ",
        "Does Earth have a leader? ",

What’s the issue? What are the error messages? How are you interpreting the error messages?

Hi I was trying to trigger the cubed_intent by inputting “what’s cube 9”, but it went to no_match_intent. I saw someone remove else and make self.no_match_intent() unintented to solve the issue, just trying to get to know why.
