Passage Summary: The chair thinks the current rulebook is too confusing and makes the team look incompetent, so they should switch to a different rulebook used by other groups.

Conclusion: The council must adopt the alternate code of parliamentary procedure to ensure their success.

Reasoning: The current code contains obscure rules that lead to petty arguments, which makes the council look bad to the public, and public confidence is necessary for the council's success.

Analysis: The chair assumes that switching to the alternate code will actually solve the problem of public confidence. To weaken this, we should look for evidence that the alternate code has its own set of problems or wouldn't actually fix the 'quibbling' issue. It is possible the public's lack of confidence stems from the council members' behavior itself rather than the specific rules they are following.
