Final answer:
The statement regarding the CLPNA quorum is false; a quorum typically requires a majority of members present. Furthermore, the Constitutional Convention did indeed meet in 1787 to revise the Articles of Confederation, and this is true.
Step-by-step explanation:
The condition that a quorum at all meetings of the CLPNA consists of 10% of regulated members present is false. To do business, each chamber typically needs a quorum, which is defined as a majority of members being present, not merely a percentage. The members need not vote but must be present and capable of voting. It is essential to check the specific organization's bylaws or governing documents for accurate quorum requirements as they can vary.
Moving on to the historical aspect, regarding Exercise 9.3.1, it is true that the Constitutional Convention met in 1787 for the purpose of revising the Articles of Confederation. The Articles of Confederation were found to be inadequate to govern the burgeoning nation, leading to the convention that resulted in the drafting of the United States Constitution.
