The correct answer is: "Greek civilization".
Greek influence started to operate after the first contacts with the Roman tribes, which were possible due to the Greek expansion throughout the Mediterranean Sea, who had established small settlements (generally cities) in many territories, called colonies.
In fact, early Romans were influenced by the Greek alphabet, adopted their gods and cults, their traditions of building temples for their deities, the coinage system, the system of weights and measures. They were also influenced by the trade activities conducted by the Greeks, by their art, literature, philosophy and science, by their administration mechanisms and their banking system.
