Why was the selection of George Washington as presiding officer of the convention crucial to its success?

i disagree that there is little difference between adult female development and adult male development. sociological studies comparing female and male pathways to adulthood, revelead that there are sustancial differences between them. particularly, female and male differ from timing of marriage, when they began to live with children and the likelihood of combining wife/husband and parent roles.

i am confused, what is the question? i can you out if you put it into more depth.
