While slave codes were in effect,
enslaved people’s activities were not restricted.
enslaved people could enter in legal contracts.
enslaved people could not be legally punished.
enslaved people’s activities were restricted.

I believe the answer is: enslaved people’s activities were restricted.

Slave codes dictate a list of activities that the slaves are banned to do in order to give the slave owners with absolute power over their salves. The codes were designed in a way to destroy's the slaves' will to run away or conducting a rebellion toward the owners.

the first historical instance of china engaging in internationalism was during the han dynasty.[1] at the start of the han dynasty, the huns in the north were attacking the frontiers of han and trying to obtain riches. emperor wu of han wanted to gain an alliance with a country called dayuezhi so the two countries could join together and fight against the huns.[2] to obtain this alliance, emperor wu sent zhang qian to the west to establish economic and cultural connections.[2] history records that during the han dynasty there were four primary avenues of contact between china and europe. they included the northern land route, the central land route, the southern sea route, and the far southern sea route.[1] the most famous of these routes is the central land route, or the classical silk road, comprising a network of roads stretching from northwest china to the ports of syria and the black sea, which passed through the oasis of the turkestans and northern persia.[1] the silk road was significant for chinese emperors because it provided dominance over central asia by developing resources and provided new markets for the export of china's most valuable resources.[1]

i belive the continental association was created to boycott all contact with british goods.

i also belive it was in december 1, 1774
