What was the cause of the mayans disappearing?

Cities began using electric lights.

Explanation: I know this is not what the question says but just if you need the answer for i ready here it is.

the navigation act prevented the colonies from exporting to countries other than britain and it prevented the importation of goods by other countries as well. so i believe the correct answer is d. other nations could not deliver goods to the colonies.

hope this .

it's no easy i swear it's hard
