Final answer:
Billie Holiday's most important musical partnership was not with Coleman Hawkins but with Lester Young, which is historically significant in jazz. Additionally, Benjamin Franklin did establish America's first abolitionist society, and William of Orange was indeed in line for the English throne through his marriage to Mary.
Step-by-step explanation:
Billie Holiday and Coleman Hawkins Partnership
The statement that Billie Holiday's most important musical partnership was with Coleman Hawkins is false. Billie Holiday, also known as 'Lady Day,' had a significant musical partnership with Lester Young, whom she nicknamed 'Prez.' They had a profound musical connection that produced memorable recordings. Hawkins was indeed a prominent tenor saxophonist during Holiday's era, but her collaboration with Young was more influential.
Benjamin Franklin's Abolitionist Society
It is true that Benjamin Franklin established the first abolitionist society in America. Franklin was a significant figure in the early movement to abolish slavery, and in 1787, he became the president of the Pennsylvania Society for Promoting the Abolition of Slavery.
William of Orange and the English Throne
The statement that Although William of Orange was married to James II's daughter, Mary, he also was in line for the throne of England is true. William and Mary ascended to the throne as co-rulers following the Glorious Revolution, which ousted James II.
The Conciliatory Proposition
The statement that In the Conciliatory Proposition, the mother country gave in to most of the demands of the American colonists is false. The proposal, introduced by British Prime Minister Lord North in 1775, sought to ease tensions but ultimately did not concede to most of American colonists' demands, leading to the continuance of the Revolutionary War.
