Answer:
a. mobile phones
Explanation:
One day some engineers decided to change the course of history. Thinking of a way to make communication more efficient and easy, they had the brilliant idea of creating a system that would be capable of communicating between cordless phones. The idea was not bad, but the technology of the time did not help much.
The real history of the mobile phone began in 1973, when the first call was made from a mobile phone to a landline. It was from April 1973 that all theories proved that the cell worked perfectly, and that the cell phone network suggested in 1947 was designed correctly. This was a not very well known moment, but it certainly was a fact marked forever because it was the moment that facilitated communication for most people through the creation of the mobile phone.
The correct answer is A. It prohibited slavery in the Northwest Territory.
Explanation:
The Northwest Ordinance was approved in 1787 to establish the Northwest territory and laws that applied to it. This covered states such as Ohio, Wisconsin, Illinois, and Indiana. Additionally, the Ordinance established the borders of this territory or states that were part of it, ratified the sovereignty, and established a local government.
Also, the ordinance ratified natural rights for all those in the territory, and therefore prohibited slavery and any similar practices. Due to this, after the ordinance, many slaves from the South scaped to this territory to gain their freedom, which contributed to the issue of slavery and related conflicts. Thus, the statement that is true about this ordinance is "It prohibited slavery in the Northwest Territory."
