Final answer:
The Etruscans influenced the Romans through advanced city planning, including sewers, roads, and bridges, and by influencing the development of the Roman alphabet.
Step-by-step explanation:
The Etruscans significantly shaped the development of Roman culture and society. Two notable ways the Etruscans influenced the Romans were through their city planning methods and the development of the Roman alphabet. The Etruscans introduced advanced urban planning, including the use of public sewers, roads, and bridges, which were influential predecessors to Rome's later urban planning feats. Additionally, the Etruscans modified the alphabet the Greeks had acquired from the Phoenicians to write their own language, and this script heavily influenced the Latin alphabet that the Romans would eventually adopt. These contributions were vital in shaping the Romans' architectural prowess and linguistic development.
