2. Select the sentence from today's reading that you feel best summarizes the importance of node ordering for Bayesian network construction. Briefly (3-5 sentences) explain why you chose this sentence.
3. Two conditional independence relations are given for nodes in a Bayesian network (p. 517): non-descendents given parents, and others given the Markov blanket. Answer the following questions from the standpoint of incorporating evidence and making inference calculations.
   1. Which do you feel is more useful? Briefly (3-5 sentences) explain your rationale.
   2. Which do you feel is more practical (i.e., computationally)? Briefly (3-5 sentences) explain your rationale.
