The name of this task connected to "Markov chain"

The main idea of that system is that the next state depends only on the current state, and there is a probability of transition.

First try shows, that one word phrases are shutting down the connection.

So we need to start with two word phrase. First hint is in the password:"talk_with_markov_about_positive_things".
