E. Roman trade expanded to include exchanges with civilizations far east.
Step-by-step explanation:
Pax Romana was a period of peace within the Roman empire that lasted for about 200 years from the establishment of the empire by Augustus Caesar to the end of the reign of Marcus Aurelius.
The Roman empire was at its most successful during this time. At some point they were led by the five good emperors who were: Nerva, Trajan, Hadrian, Antoninus Pius, and Marcus Aurelius.
During this period, Roman traders went as far as civilizations like China and traded with them. This increased Roman trade as well as the level of incomes in the empire.
