The correct answer to this open question is the following.
In the past, archeologists used basic elements to dig the soil and start the excavations. Let's have in mind that the first Egyptian discoveries were made by the Napoleonic troops during their campaigns in North Africa, specifically, Egypt.
Then, archeologists from France and later Britain visited the zone to start their excavations projects based on the information, codes, and maps collected in those years.
It was until some French discovered the Rosetta Stone, close to Rosseta, Egypt, that archeologists could decipher the Egyptian hieroglyphs. This allowed a full interpretation of the Egyptian scripture and made archeologists locate sites such as the Valley of the Kings and the Valley of the Queens in Luxor, Egypt. Places, where most of the tombs, have been found.
Once there, archeologists hired many people to start excavations and that is basically how they found the tombs and the mommies.
The Egyptian mummy project used CAT scans, a forensic technique to collect information about the gender and time of the mummies.
Modern-day techniques and state of the art technology have increased the finding of new discoveries in Egypt. We are talking about Computer Tomography or CT. It is a non-invasive technique that allows scientists and archeologists to study mummies and get valuable information because it uses a scanner that provides three-dimensional information without affecting the mummy.
Answer:
by conquering neighboring territories
Explanation:
The Romans were initially a relatively small tribe based around Rome, and they were not even the biggest tribe in Italy. They started to reform their military though, and one by one started to attack and conquer the neighboring countries, giving the initial rise of the Roman Empire. In order to be able to control the conquered people, the Romans were quick to assimilate everyone that they have conquered, thus making them Romans, which instead of being a burden were contributing to the empire. As the empire grew stronger in wealth, military power, numbers, and ambitions, they started to attack the other tribes, like the numerous Celtic tribes, and Germanic tribes. Later the expansion continued with taking over the Iberian Peninsula, the Phoenician colonies, part of the Barber territory, the northern half of the Balkans, and after three wars with Macedonia they managed to conquer the southern part of the Balkans too. Everywhere they went, the Romans used the same method as they started, assimilation through imposing their culture and language, and of course rule.
