English and French Kingdoms had both similarities and differences, during the late 1600's.
Both had a monarchical system, with a king ruling the country.
However, France had been under the rule of Louis XIV for over 60 years by the end of the 17th century, thus, he had consolidated his power, and the crown's power above everything. He eliminated the remnants of feudalism still left across France and imposed a rule of absolute monarchy.
In contrast to the English kingdom, where the parliament was powerful enough to denounce King James II for abuse of power through the use of the Bill of Rights, and was a solid institution with the authority to depose the king if needed. The English kingdom had clear limits on the Crown's power and authority, and several tax and civil right laws could not be emitted without the Parliaments permission.
The correct answer is A. The invention of the cotton gin.
Explanation
A cotton gin is a machine created during the late 18th century that has the utility of separating cotton fibers from their seeds and other objects attached to it quickly and easily. The invention of this machine contributed to the strengthening of slavery because it allowed the landowners of the south to start the domestic production of cotton cheaply and easily. However, once the export demand for cotton grew in the north and other countries, the landowners of the south acquired more slaves to supply that demand for cotton. This deepened slavery because none of the southern landowners wanted to set free the African-Americans who were bringing them huge profits from their work. So the correct answer is A.
