Final answer:
The number of men selected as charter members varies according to the specific historic event; however, specific numbers are not provided in the references for the Massachusetts Bay Charter, the Constitutional Convention, or other historical formations.
Step-by-step explanation:
The question of how many men were selected as charter members varies according to historical context. In the case of the Massachusetts Bay Charter of 1629, the 'freemen' who could govern totaled over a hundred, including a governor, an assistant governor, and the General Court, which means there could have been quite a number of charter members. However, there is no exact figure provided in the reference material. During the Virginia House of Burgesses in 1619, there were twenty-two burgesses, which were men elected as representatives.
Moreover, when analyzing the founding of the U.S. Constitution, it was during the Constitutional Convention that twenty-nine delegates from nine states, who were predominantly men, met to lay out a new plan of government. While the exact number of 'charter members' in this sense isn't specified, it highlights the involvement of men in foundational moments of governance in early American history.
