When archaeologists excavate our American cities 5000 years from now, what man-made material do you think will provide them with the most precise information for identifying the date of an archaeological context ?

There would be man-made materials that will provide archaeologists with the most precise information for identifying the date of an archaeological context.

Explanation:

Archaeological context is the place or site where the artifact is found.

This site is monitored and constant surveillance happens. There are records of artifacts, bio-facts or even cultural information which should be recorded in case artifact needs to be referred to in future. This information will also help in future assessment.

There are different dating methods employed by the archaeologists to identify the age or date of the artifact. The soil of the artifact, the layer and what type of site it is all contribute to the factors to determine the age of the artifact.

first, the romans stayed isolated because they had to defend their own territories from neighboring cities that were harassing them, like the etruscans. second, once the romans managed to defeat their neighbors, and started to expand their territory, they started to build roads and bridges. finally, now that the romans have covered their territory with roads functioning as highways, they could mobilize their legions faster to assemble larger military units in a specific place.
