The statements that correctly describe political, social, or cultural changes that took place in Rome during the early empire are:
- new buildings and temples, many made of marble
The other statements—about wars within the empire and foreign powers, duty to pay taxes and serve in the army for citizens, and decline in prosperity and political influence abroad—do not accurately reflect the primary characteristics of the early empire in Rome, particularly in the context of cultural and social changes. The early empire, especially under leaders like Augustus, is often characterized by stability, prosperity, and significant architectural achievements, rather than widespread warfare and decline.
