Answer: C. by recording laws and legal decisions
Step-by-step explanation:
The Romans left a lasting legacy by inventing and modifying technology and ways of life that were and are still used in the present era especially in the area of Law. Concepts such as civil rights, contract, legal wills and even trial by jury have Roman foundations to them.
The world was able to hear about this because the Romans recorded some of their laws and legal decisions such as in the Twelve Tables and the Corpus Iuris Civilis.
Of particular relevance is the Corpus Iuris Civilis which was compiled under Emperor Justinian. It was a collection of Roman law that was then codified and passed around the Byzantine empire.
