The character of Chairman Reed in this passage has the role of an effective moderator on the grounds that before formaly starting with the discussion, he reminds the members of it of participanting only until the end when everything is said and done from Mrs. Louis and Mr. Hollembeak; also, at the same time, Chairman Reed wants to hear the opinion of Mr. Hollembeak about the case as he was willing to discuss, which the chairman asked him later to show support. Another thing to said is that it was not the Chairman Reed who challenged Mr. Hollembeak but Mrs. Louis, who seemed to interrogate him along the dicussion. Thus, the correct option for this is A <em>"Effective. Chairman Reed is reminding participants of the rules for discussion, acknowledging Mr. Hollembeak’s point of view, and asking him to support his point of view with facts."</em>
