Answer:
I may be incorrect but I think it is B. Roman Religion.
There are four choices;
A. Daily life in Rome.
B. Roman religion.
C. The founding of Rome.
D. The Roman emperor Augustus.
And to me, B sounds the most reasonable from what I know about the story which is a story about a character who left Rome and traveled to Italy. Where he became the ancestor of Romans.
I know the answer isn´t C because the founding of Rome was a different story about two brothers. And there isn´t anything in the story about Augustus, I think, so it can´t be D. So it would be A or B, and B seems more reasonable.
